NAME

       amanda.conf - Main configuration file for Amanda, the Advanced Maryland Automatic Network
       Disk Archiver

DESCRIPTION

       amanda.conf(5) is the main configuration file for Amanda. This manpage lists the relevant
       sections and parameters of this file for quick reference.

       The file <CONFIG_DIR>/<config>/amanda.conf is loaded.

SYNTAX

       There are a number of configuration parameters that control the behavior of the Amanda
       programs. All have default values, so you need not specify the parameter in amanda.conf if
       the default is suitable.

   COMMENTS
       Lines starting with # are ignored, as are blank lines. Comments may be placed on a line
       with a directive by starting the comment with a #. The remainder of the line is ignored.

   KEYWORDS AND IDENTIFIERS
       Keywords are case insensitive, i.e.  mailto and MailTo are treated the same. Also, the
       characters '-' and '_' are interchangeable in all predefined Amanda keywords:
       device_property and device-property have the same meaning. This manpage uses the dashed
       versions, but the underscored versions will be accepted for backward compatibility

       Identifiers are names which are defined in the configuration itself, such as dumptypes or
       interfaces. Identifiers are are case-insensitive, but sensitive to '-' vs. '_'.
       Identifiers should be quoted in the configuration file, although For historical reasons,
       the quotes are optional.

       Strings are always quoted with double quotes ("), and any double quotes or backslashes
       within the string are escaped with a backslash:

       tapelist "/path/to/tapelist"
       property "escaped-string" "escaping: \\ (backslash) and \" (double-quote)"

       To summarize, then:

                                 # QUOTES        CASE            -/_
       logdir "logs"             # required      sensitive       sensitive
       send-amreport-on strange  # prohibited    insensitive     insensitive
       tapetype "EXABYTE"        # optional      insensitive     sensitive

       define dumptype "dt" {    # optional      insensitive     sensitive
         "dumptype-common"       # optional      insensitive     sensitive
         strategy noinc          # prohibited    insensitive     insensitive
       }

   VALUE SUFFIXES
       Integer arguments may have one of the following (case insensitive) suffixes, some of which
       have a multiplier effect:

       b byte bytes
           Some number of bytes.

       bps
           Some number of bytes per second.

       k kb kbyte kbytes kilobyte kilobytes
           Some number of kilobytes (bytes*1024).

       kps kbps
           Some number of kilobytes per second (bytes*1024).

           It is the default multiplier for all size options.

       m mb meg mbyte mbytes megabyte megabytes
           Some number of megabytes (bytes*1024*1024).

       mps mbps
           Some number of megabytes per second (bytes*1024*1024).

       g gb gbyte gbytes gigabyte gigabytes
           Some number of gigabytes (bytes*1024*1024*1024).

       t tb tbyte tbytes terabyte terabytes
           Some number of terabytes (bytes*1024*1024*1024*1024).

       tape tapes
           Some number of tapes.

       day days
           Some number of days.

       week weeks
           Some number of weeks (days*7).

               Note
               The value inf may be used in most places where an integer is expected to mean an
               infinite amount.

               Boolean arguments may have any of the values 1, y, yes, t, true or on to indicate
               a true state, or 0, n, no, f, false or off to indicate a false state. If no
               argument is given, true is assumed.

   PARAMETER ORDER
       In general, the order in which parameters occur in the configuration file does not matter,
       with the exception of subsection inheritance. For example, if dumptype "normal-encrypt"
       which inherits from dumptype "normal", then "normal" must appear first in the
       configuration file.

   STRINGS
       Quoted strings in Amanda follow a common, C-like syntax. Printable characters and
       whitespace are kept as-is, except that the backslash character (\) is used as an escape
       character, and a double-quote ends the string. The allowed escape sequences are

           ESCAPE SEQUENCE     BECOMES
           \\                  \
           \"                  "
           \n                  (newline)
           \t                  (tab)
           \r                  (carriage return)
           \f                  (form-feed)
           \1 - \7
           \01 - \77
           \001 - \377         (character specified in octal)
       Illegally quoted strings are handled on a "best-effort" basis, which may lead to
       unexpected results.

       Examples:

       finserver "/data/finance/XYZ Corp's \"real\" finances" finance-high eth0 -1
       property "syspath" "C:\\WINDOWS\\SYSTEM"

   SUBSECTIONS AND INHERITANCE
       Amanda configuration files may include various subsections, each defining a set of
       configuration directives. Each type of subsection is described below. Note that all types
       of subsections can inherit from other subsections of the same type by naming the "parent"
       section in the "child" subsection. For example:

       define dumptype global {
           record yes
           index yes
       }

       define dumptype nocomp {
           global      # inherit the parameters in dumptype 'global'
           compress none
       }

       Note that multiple inheritance is also supported by simply naming multiple parent sections
       in a child. Parents are implicitly expanded in place in a child, and the last occurrence
       of each parameter takes precedence. For example,

       define tapetype par1 {
           comment "Parent 1"
           filemark 8k
           speed 300bps
           length 200M
       }
       define tapetype par2 {
           comment "Parent 2"
           filemark 16k
           speed 400bps
       }
       define tapetype child {
           par1
           par2
           filemark 32k
       }
       In this example, 'child' will have a filemark of 32k, a speed of 400bps, and a length of
       200M.

GLOBAL PARAMETERS

       org string
           Default: "daily". A descriptive name for the configuration. This string appears in the
           Subject line of mail reports. Each Amanda configuration should have a different string
           to keep mail reports distinct.

       mailer string
           Default found by configure. A mail program that can send mail with 'MAILER -s
           "subject" user < message_file'.

       mailto string
           Default: none. A space separated list of recipients for mail reports. If not
           specified, amdump will not send any mail.

       send-amreport-on [ all | strange | error | never ]
           Default: all. Specify which types of messages will trigger an email from amreport.
           amreport is used by amdump and amflush.

           all
               Send an email on any message.

           strange
               Send an email on strange or error message. A strange message occurs when the dump
               succeeded, but returned one or more errors unknown to Amanda.

           error
               Send an email only on error messages.

           never
               Never send an email.

       report-use-media boolean
           Default: True if max-dle-by-volume is not set, False if it is set. If the reporter
           must print the list of media used in the run.

       report-next-media boolean
           Default: True if max-dle-by-volume is not set, False if it is set. If the reporter
           must print the list of media expected for the next run.

       max-dle-by-volume int
           Default: 1000000000. The maximum number of dle written to a single volume.

       dumpcycle int
           Default: 10 days. The number of days in the backup cycle. Each disk will get a full
           backup at least this often. Setting this to zero tries to do a full backup each run.

               Note
               This parameter may also be set in a specific dumptype (see below). This value sets
               the default for all dumptypes so must appear in amanda.conf before any dumptypes
               are defined.

       runspercycle int
           Default: same as dumpcycle. The number of amdump runs in dumpcycle days. A value of 0
           means the same value as dumpcycle. A value of -1 means guess the number of runs from
           the tapelist(5) file, which is the number of tapes used in the last dumpcycle days /
           runtapes.

       tapecycle int
           Default: 15 tapes. Specifies the number of "active" volumes - volumes that Amanda will
           not overwrite. While Amanda is always willing to write to a new volume, it refuses to
           overwrite a volume unless at least 'tapecycle -1' volumes have been written since.

           It is considered good administrative practice to set the tapecycle parameter slightly
           lower than the actual number of tapes in use. This allows the administrator to more
           easily cope with damaged or misplaced tapes or schedule adjustments that call for
           slight adjustments in the rotation order.

           Note: Amanda is commonly misconfigured with tapecycle equal to the number of tapes per
           dumpcycle. In this misconfiguration, amanda may erase a full dump before a new one is
           completed. Recovery is then impossible. The tapecycle must be at least one tape larger
           than the number of tapes per dumpcycle.

           The number of tapes per dumpcycle is calculated by multiplying the number of amdump
           runs per dump cycle runspercycle (the number of amdump runs per dump cycle) and
           runtapes (the number of tapes used per run). Typically tapecycle is set to two or four
           times the tapes per dumpcycle.

       usetimestamps bool
           Default: Yes. This option allows Amanda to track multiple runs per calendar day. The
           only reason one might disable it is that Amanda versions before 2.5.1 can't read
           logfiles written when this option was enabled.

       label-new-tapes string
           Deprecated, use autolabel option with options volume-error empty to get equivalent
           behavior.

           Default: not set. When set, this directive will cause Amanda to automatically write an
           Amanda tape label to any blank tape she encounters.

       autolabel string [any] [other-config] [non-amanda] [volume-error] [empty]
           Default: not set. When set, this directive will cause Amanda to automatically write an
           Amanda tape label to most volume she encounters. This option is DANGEROUS because when
           set, Amanda may erase near-failing tapes or tapes accidentally loaded in the wrong
           slot.

           When using this directive, specify the template for new tape labels. The template can
           contains many variables that are substituted by their values:

               $c : config name
               $o : org configuration
               $b : barcode of the volume
               $s : slot number, can specify a minimun number of digit:
                    $3s to get '001'
               $m : meta label

           The template can contain some number of contiguous '%' characters, which will be
           replaced with a generated number. Be sure to specify enough '%' characters that you do
           not run out of tape labels. Example: "DailySet1-%%%", "$c-%%%", "$m-%%%", "$m-$b"

           The generared label can be used only if it match the labelstr setting. The volume will
           not be used if the generated label doesn't match the labelstr setting.

           Note that many devices cannot distinguish an empty tape from an error condition, so it
           may is often necessary to include volume-error as an autolabel condition.

           any
               equivalent to 'other-config non-amanda volume-error empty'

           other-config
               Label volumes with a valid Amanda label that do not match our labelstr. Danger:
               this may erase volumes from other Amanda configurations without warning!

           non-amanda
               Label volumes which do not start with data that resembles an Amanda header.
               Danger: this may erase volumes from other backup applications without warning!

           volume-error
               Label volumes where an error occurs while trying to read the label.  Danger: this
               may erase arbitrary volumes due to transient errors.

           empty
               Label volumes where a read returns 0 bytes.

       meta-autolabel string
           Default: not set. When set and if the changer support meta-label, this directive will
           cause Amanda to automatically add a meta-label to a meta-volume.

           A meta-volume is a containers that contains many volumes, eg. a removable hard-disk
           for use with chg-disk, each hard disk have many slots (volume). The meta-label is the
           label to put on the meta-volume.

           When using this directive, specify the template for new meta labels. The template can
           contains many variables that are substituted by their values:

               $c : config name
               $o : org configuration

           The template should contain some number of contiguous '%' characters, which will be
           replaced with a generated number. Be sure to specify enough '%' characters that you do
           not run out of meta labels. Example: "DailySet1-%%%", "$o-%%%",

       dumpuser string
           Default: "amanda". The login name Amanda uses to run the backups. The backup client
           hosts must allow access from the tape server host as this user via .rhosts or
           .amandahosts, depending on how the Amanda software was built.

       printer string
           Printer to use when doing tape labels. See the lbl-templ tapetype option.

       tapedev string
           Default: "null:". This parameter can either specify a device (explicitly or by
           referencing a device definition - see amanda-devices(7)) or a tape changer (explicitly
           or by referencing a device definition - see amanda-changers(7)).

       device-property string string
           These options can set various device properties. See amanda-devices(7) for more
           information on device properties and their syntax. Both strings are always quoted; the
           first string contains the name of the property to set, and the second contains its
           value. For example, to set a fixed block size of 128k, write:
           device-property "BLOCK_SIZE" "128k"

       property [append] string string+
           These options can set various properties, they can be used by third party software to
           store information in the configuration file. Both strings are quoted; the first string
           contains the name of the property to set, and the others contains its values.  append
           keyword append the values to the list of values for that property.

       tpchanger string
           Default: not set. The tape changer to use. In most cases, only one of tpchanger or
           tapedev is specified, although for backward compatibility both may be specified if
           tpchanger gives the name of an old changer script. See amanda-changers(7) for more
           information on configuring changers.

       interactivity string
           Default: not set. The interactivity module Amanda should use to interact with the
           user. See amanda-interactivity(7) for a list of modules.

       taperscan string
           Default: traditional. The taperscan module amanda should use to find a tape to write
           to. See amanda-taperscan(7) for a list of modules.

       changerdev string
           Default: "dev/null". A tape changer configuration parameter. Usage depends on the
           particular changer defined with the tpchanger option.

       changerfile string
           Default: "/usr/adm/amanda/log/changer-status". A tape changer configuration parameter.
           Usage depends on the particular changer defined with the tpchanger option.

       runtapes int
           Default: 1. The maximum number of tapes used in a single run. If a tape changer is not
           configured, this option is not used and should be commented out of the configuration
           file.

           If a tape changer is configured, this may be set larger than one to let Amanda write
           to more than one tape.

           Note that this is an upper bound on the number of tapes, and Amanda may use less.

       maxdumpsize int
           Default: runtapes*tape-length. Maximum number of bytes the planner will schedule for a
           run.

           The default unit is Kbytes if it is not specified.

       taperalgo [ first | firstfit | largest | largestfit | smallest | last ]
           Default: first. The algorithm used to choose which dump image to send to the taper.

           first
               First in, first out.

           firstfit
               The first dump image that will fit on the current tape.

           largest
               The largest dump image.

           largestfit
               The largest dump image that will fit on the current tape.

           smallest
               The smallest dump image.

           last
               Last in, first out.

       taper-parallel-write int
           Default: 1. Amanda can write simultaneously up to that number of volume at any given
           time. The changer must have as many drives.

       eject-volume int
           Default: no. Set to yes if you want the volume to be ejected after Amanda wrote data
           to it. It works only with some changer and device.

       labelstr string
           Default: ".*". The tape label constraint regular expression. All tape labels generated
           (see amlabel(8)) and used by this configuration must match the regular expression. If
           multiple configurations are run from the same tape server host, it is helpful to set
           their labels to different strings (for example, "DAILY[0-9][0-9]*" vs.
           "ARCHIVE[0-9][0-9]*") to avoid overwriting each other's tapes.

       tapetype string
           Default: no default. The type of tape drive associated with tapedev or tpchanger. This
           refers to one of the defined tapetypes in the config file (see below), which specify
           various tape parameters, like the length, filemark size, and speed of the tape media
           and device.

       ctimeout int
           Default: 30 seconds. Maximum amount of time that amcheck will wait for each client
           host.

       dtimeout int
           Default: 1800 seconds. Amount of idle time per disk on a given client that a dumper
           running from within amdump will wait before it fails with a data timeout error.

       etimeout int
           Default: 300 seconds. Amount of time per estimate on a given client that the planner
           step of amdump will wait to get the dump size estimates (note: Amanda runs up to 3
           estimates for each DLE). For instance, with the default of 300 seconds and four DLE's,
           each estimating level 0 and level 1 on client A, planner will wait up to 40 minutes
           for that machine. A negative value will be interpreted as a total amount of time to
           wait per client instead of per disk.

       connect-tries int
           Default: 3. How many times the server will try a connection.

       req-tries int
           Default: 3. How many times the server will resend a REQ packet if it doesn't get the
           ACK packet.

       netusage int
           Default: 80000 Kbps. The maximum network bandwidth allocated to Amanda, in Kbytes per
           second. See also the interface section.

       inparallel int
           Default: 10. The maximum number of backups that Amanda will attempt to run in
           parallel. Amanda will stay within the constraints of network bandwidth and holding
           disk space available, so it doesn't hurt to set this number a bit high. Some
           contention can occur with larger numbers of backups, but this effect is relatively
           small on most systems.

       displayunit "k|m|g|t"
           Default: "k". The unit used to print many numbers, k=kilo, m=mega, g=giga, t=tera.

       dumporder string
           Default: "tttTTTTTTT". The priority order of each dumper:

           s: smallest size
           S: largest size
           t: smallest time
           T: largest time
           b: smallest bandwidth
           B: largest bandwidth

       maxdumps int
           Default: 1. The maximum number of backups from a single host that Amanda will attempt
           to run in parallel. See also the inparallel option.

           Note that this parameter may also be set in a specific dumptype (see below). This
           value sets the default for all dumptypes so must appear in amanda.conf before any
           dumptypes are defined.

       bumpsize int
           Default: 10 Mbytes. The minimum savings required to trigger an automatic bump from one
           incremental level to the next, expressed as size. If Amanda determines that the next
           higher backup level will be this much smaller than the current level, it will do the
           next level. The value of this parameter is used only if the parameter bumppercent is
           set to 0.

           The default unit is Kbytes if it is not specified.

           The global setting of this parameter can be overwritten inside of a
           dumptype-definition.

           See also the options bumppercent, bumpmult and bumpdays.

       bumppercent int
           Default: 0. The minimum savings required to trigger an automatic bump from one
           incremental level to the next, expressed as percentage of the current size of the DLE
           (size of current level 0). If Amanda determines that the next higher backup level will
           be this much smaller than the current level, it will do the next level.

           If this parameter is set to 0, the value of the parameter bumpsize is used to trigger
           bumping.

           The global setting of this parameter can be overwritten inside of a
           dumptype-definition.

           See also the options bumpsize, bumpmult and bumpdays.

       bumpmult float
           Default: 1.5. The bump size multiplier. Amanda multiplies bumpsize by this factor for
           each level. This prevents active filesystems from bumping too much by making it harder
           to bump to the next level. For example, with the default bumpsize and bumpmult set to
           2.0, the bump threshold will be 10 Mbytes for level one, 20 Mbytes for level two, 40
           Mbytes for level three, and so on.

           The global setting of this parameter can be overwritten inside of a
           dumptype-definition.

       bumpdays int
           Default: 2 days. To insure redundancy in the dumps, Amanda keeps filesystems at the
           same incremental level for at least bumpdays days, even if the other bump threshold
           criteria are met.

           The global setting of this parameter can be overwritten inside of a
           dumptype-definition.

       diskfile string
           Default: "disklist". The file name for the disklist file holding client hosts, disks
           and other client dumping information.

       infofile string
           Default: "/usr/adm/amanda/curinfo". The file or directory name for the historical
           information database. If Amanda was configured to use DBM databases, this is the base
           file name for them. If it was configured to use text formated databases (the default),
           this is the base directory and within here will be a directory per client, then a
           directory per disk, then a text file of data.

       logdir string
           Default: "/usr/adm/amanda". The directory for the amdump and log files.

       indexdir string
           Default "/usr/adm/amanda/index". The directory where index files (backup image
           catalogues) are stored. Index files are only generated for filesystems whose dumptype
           has the index option enabled.

       tapelist string
           Default: "tapelist". The file name for the active tapelist(5). Amanda maintains this
           file with information about the active set of tapes.

       device-output-buffer-size int
           Default: 1280k. Controls the amount of memory used by Amanda to hold data as it is
           read from the network or disk before it is written to the output device. Higher values
           may be useful on fast tape drives and optical media.

           The default unit is bytes if it is not specified.

       tapebufs int
           Default: 20. This option is deprecated; use the device-output-buffer-size directive
           instead.  tapebufs works the same way, but the number specified is multiplied by the
           device blocksize prior to use.

       reserve int
           Default: 100. The part of holding-disk space that should be reserved for incremental
           backups if no tape is available, expressed as a percentage of the available
           holding-disk space (0-100). By default, when there is no tape to write to, degraded
           mode (incremental) backups will be performed to the holding disk. If full backups
           should also be allowed in this case, the amount of holding disk space reserved for
           incrementals should be lowered.

       autoflush no|yes|all
           Default: no. Whether an amdump run will flush the dumps from holding disk to tape.
           With yes, only dump matching the command line argument are flushed. With all, all dump
           are flushed.

       amrecover-do-fsf bool
           Deprecated; amrecover always uses fsf, and does not invoke amrestore.

           Default: on. Amrecover will call amrestore with the -f flag for faster positioning of
           the tape.

       amrecover-check-label bool
           Deprecated; amrecover always checks the label, and does not invoke amrestore.

           Default: on. Amrecover will call amrestore with the -l flag to check the label.

       amrecover-changer string
           Default: not set. Amrecover will use the changer if you use 'settape <string>' and
           that string is the same as the amrecover-changer setting.

       columnspec string
           default:
           "HostName=0:-12:12,Disk=1:-11:11,Level=1:-1:1,OrigKB=1:-7:0,OutKB=1:-7:0,Compress=1:-6:1,DumpTime=1:-7:7,Dumprate=1:-6:1,TapeTime=1:-6:6,TapeRate=1:-6:1"

           Defines the width of columns amreport should use.  String is a comma (',') separated
           list of triples. Each triple consists of three parts which are separated by a equal
           sign ('=') and a colon (':') (see the example). These four parts specify:

            1. the name of the column, which may be:

                    Compress (compression ratio)
                    Disk (client disk name)
                    DumpRate (dump rate in KBytes/sec)
                    DumpTime (total dump time in hours:minutes)
                    HostName (client host name)
                    Level (dump level)
                    OrigKB (original image size in KBytes)
                    OutKB (output image size in KBytes)
                    TapeRate (tape writing rate in KBytes/sec)
                    TapeTime (total tape time in hours:minutes)

            2. the amount of space to display before the column (used to get whitespace between
               columns).

            3. the width of the column itself. If set to a negative value, the width will be
               calculated on demand to fit the largest entry in this column.

            4. the precision of the column, number of digit after the decimal point for number.

           Here is an example:

           columnspec "Disk=1:18,HostName=0:10,OrigKB=::2,OutKB=1:7"

           The above will display the disk information in 18 characters and put one space before
           it. The hostname column will be 10 characters wide with no space to the left. The
           Original KBytes print 2 decimal digit. The output KBytes column is seven characters
           wide with one space before it.

       includefile string
           Default: no default. The name of an Amanda configuration file to include within the
           current file. Useful for sharing dumptypes, tapetypes and interface definitions among
           several configurations. Relative pathnames are relative to the configuration
           directory.

       debug-days int
           Default: 3. The number of days the debug files are kept.

       debug-auth int
           Default: 0. Debug level of the auth module

       debug-event int
           Default: 0. Debug level of the event module

       debug-holding int
           Default: 0. Debug level of the holdingdisk module

       debug-protocol int
           Default: 0. Debug level of the protocol module

       debug-planner int
           Default: 0. Debug level of the planner process

       debug-driver int
           Default: 0. Debug level of the driver process

       debug-dumper int
           Default: 0. Debug level of the dumper process

       debug-chunker int
           Default: 0. Debug level of the chunker process

       debug-taper int
           Default: 0. Debug level of the taper process

       debug-recovery int
           Default: 1. Debug level of all recovery process

       flush-threshold-dumped int
           Default: 0. Amanda will not begin writing data to a new volume until the amount of
           data on the holding disk is at least this percentage of the volume size. In other
           words, Amanda will not begin until the amount of data on the holding disk is greater
           than the tape length times this parameter. This parameter may be larger than 100%, for
           example to keep more recent dumps on the holding disk for faster recovery.

           Needless to say, your holding disk must be big enough that this criterion could be
           satisfied. If the holding disk cannot be used for a particular dump (because, for
           example, there is no remaining holding space) then Amanda will disregard the
           constraint specified by this setting and start a new volume anyway. Once writing to a
           volume has begun, this constraint is not applied unless and until a new volume is
           needed.

           The value of this parameter may not exceed than that of the flush-threshold-scheduled
           parameter.

       flush-threshold-scheduled int
           Default: 0. Amanda will not begin writing data to a new volume until the sum of the
           amount of data on the holding disk and the estimated amount of data remaining to be
           dumped during this run is at least this percentage of the volume size. In other words,
           Amanda will not begin until the inequality h + s > t × d is satisfied, where h is the
           amount of data on the holding disk, s is the total amount of data scheduled for this
           run but not dumped yet, t is the capacity of a volume, and d is this parameter,
           expressed as a percentage. This parameter may be larger than 100%.

           Needless to say, your holding disk must be big enough that this criterion could be
           satisfied. If the holding disk cannot be used for a particular dump (because, for
           example, there is no remaining holding space) then Amanda will disregard the
           constraint specified by this setting and start a new volume anyway. Once writing to a
           volume has begun, this constraint is not applied unless and until a new volume is
           needed.

           The value of this parameter may not be less than that of the flush-threshold-dumped or
           taperflush parameters.

       taperflush int
           Default: 0. At the end of a run, Amanda will start a new tape to flush remaining data
           if there is more data on the holding disk at the end of a run than this setting
           allows; the amount is specified as a percentage of the capacity of a single volume. In
           other words, at the end of a run, Amanda will begin a new tape if the inequality h > t
           × f is satisfied, where h is the amount of data remaining on the holding disk from
           this or previous runs, t is the capacity of a volume, and f is this parameter,
           expressed as a percentage. This parameter may be greater than 100%.

           The value of this parameter may not exceed that of the flush-threshold-scheduled
           parameter.; autoflush must be set to 'yes' if taperflush is greater than 0.

       reserved-udp-port int,int
           Default: --with-udpportrange or 512,1023. Reserved udp port that will be used (bsd,
           bsdudp). Range is inclusive.

       reserved-tcp-port int,int
           Default: --with-low-tcpportrange or 512,1023. Reserved tcp port that will be used
           (bsdtcp). Range is inclusive.

       unreserved-tcp-port int,int
           Default: --with-tcpportrange or 1024,65535. Unreserved tcp port that will be used
           (bsd, bsdudp). Range is inclusive.

       recovery-limit [ string | same-host | server]
           Default: none (no limitations). This parameter limits the hosts that may do
           recoveries. Hosts are identified by their authenticated peer name, as described in
           amanda-auth(7); if this is not available and the recovery-limit parameter is present,
           recovery will be denied. The arguments to the parameter are strings giving host match
           expressions (see amanda-match(7)) or the special keywords same-host or server. The
           same-host keyword requires an exact match to the hostname of the DLE being recovered.
           The server keyword require the connection come from the fqdn of the server. Specifying
           no arguments at all will disable all recoveries from any host.

           Note that match expressions can be constructed to be forgiving of e.g.,
           fully-qualified vs. unqualified hostnames, but same-host requires an exact match.

           The error messages that appear in amrecover are intentionally vague to avoid
           information leakage. Consult the amindexd debug log for more details on the reasons a
           recovery was rejected.

           Recovery limits can be refined on a per-DLE basis using the dumptype parameter of the
           same name. Note that the default value will apply to any dumpfiles for disks which no
           longer appear in the disklist; thus leaving the global parameter at its default value
           but setting it for all DLEs is not sufficient to maintain secure backups.

       tmpdir string
           Default: none (system default). Set it to a directory with lots of free space if sort
           in amindexd fail with 'No space left on device'.

HOLDINGDISK SECTION

       The amanda.conf file may define one or more holding disks used as buffers to hold backup
       images before they are written to tape. The syntax is:
       define holdingdisk name {
           holdingdisk-option holdingdisk-value
           ...
       }

       The { must appear at the end of a line, and the } on its own line.

       Name is a logical name for this holding disk.

       The options and values are:

       comment string
           Default: not set. A comment string describing this holding disk.

       directory string
           Default: "/dumps/amanda". The path to this holding area.

       use int
           Default: 0 Gb. Amount of space that can be used in this holding disk area. If the
           value is zero, all available space on the file system is used. If the value is
           negative, Amanda will use all available space minus that value.

       chunksize int
           Default: 1 Gb. Holding disk chunk size. Dumps larger than the specified size will be
           stored in multiple holding disk files. The size of each chunk will not exceed the
           specified value. However, even though dump images are split in the holding disk, they
           are concatenated as they are written to tape, so each dump image still corresponds to
           a single continuous tape section.

           The default unit is Kbytes if it is not specified.

           If 0 is specified, Amanda will create holding disk chunks as large as
           ((INT_MAX/1024)-64) Kbytes.

           Each holding disk chunk includes a 32 Kbyte header, so the minimum chunk size is 64
           Kbytes (but that would be really silly).

           Operating systems that are limited to a maximum file size of 2 Gbytes actually cannot
           handle files that large. They must be at least one byte less than 2 Gbytes. Since
           Amanda works with 32 Kbyte blocks, and to handle the final read at the end of the
           chunk, the chunk size should be at least 64 Kbytes (2 * 32 Kbytes) smaller than the
           maximum file size, e.g. 2047 Mbytes.

DUMPTYPE SECTION

       The amanda.conf(5) file may define multiple sets of backup options and refer to them by
       name from the disklist(5) file. For instance, one set of options might be defined for file
       systems that can benefit from high compression, another set that does not compress well,
       another set for file systems that should always get a full backup and so on.

       A set of backup options are entered in a dumptype section, which looks like this:
       define dumptype "name" {
           dumptype-option dumptype-value
           ...
       }

       The { must appear at the end of a line, and the } on its own line.

       Name is the name of this set of backup options. It is referenced from the disklist(5)
       file.

       Some of the options in a dumptype section are the same as those in the main part of
       amanda.conf(5). The main option value is used to set the default for all dumptype
       sections. For instance, setting dumpcycle to 50 in the main part of the config file causes
       all following dumptype sections to start with that value, but the value may be changed on
       a section by section basis. Changes to variables in the main part of the config file must
       be done before (earlier in the file) any dumptypes are defined.

       The dumptype options and values are:

       auth string
           Default: "bsdtcp". Type of authorization to perform between tape server and backup
           client hosts. See amanda-auth(7) for more detail.

       amandad-path string
           Default: "$libexec/amandad". Specify the amandad path of the client, only use with
           rsh/ssh authentification.

       client-username string
           Default: CLIENT_LOGIN. Specify the username to connect on the client, only use with
           rsh/ssh authentification.

       client-port [ int | string ]
           Default: "amanda". Specifies the port to connect to on the client. It can be a service
           name or a numeric port number.

       bumpsize int
           Default: 10 Mbytes. The minimum savings required to trigger an automatic bump from one
           incremental level to the next, expressed as size. If Amanda determines that the next
           higher backup level will be this much smaller than the current level, it will do the
           next level. The value of this parameter is used only if the parameter bumppercent is
           set to 0.

           The default unit is Kbytes if it is not specified.

           See also the options bumppercent, bumpmult and bumpdays.

       bumppercent int
           Default: 0. The minimum savings required to trigger an automatic bump from one
           incremental level to the next, expressed as percentage of the current size of the DLE
           (size of current level 0). If Amanda determines that the next higher backup level will
           be this much smaller than the current level, it will do the next level.

           If this parameter is set to 0, the value of the parameter bumpsize is used to trigger
           bumping.

           See also the options bumpsize, bumpmult and bumpdays.

       bumpmult float
           Default: 1.5. The bump size multiplier. Amanda multiplies bumpsize by this factor for
           each level. This prevents active filesystems from bumping too much by making it harder
           to bump to the next level. For example, with the default bumpsize and bumpmult set to
           2.0, the bump threshold will be 10 Mbytes for level one, 20 Mbytes for level two, 40
           Mbytes for level three, and so on.

       bumpdays int
           Default: 2 days. To insure redundancy in the dumps, Amanda keeps filesystems at the
           same incremental level for at least bumpdays days, even if the other bump threshold
           criteria are met.

       comment string
           Default: not set. A comment string describing this set of backup options.

       comprate float [, float ]
           Default: 0.50, 0.50. The expected full and incremental compression factor for dumps.
           It is only used if Amanda does not have any history information on compression rates
           for a filesystem, so should not usually need to be set. However, it may be useful for
           the first time a very large filesystem that compresses very little is backed up.

       compress [ none | client | server ] [ best | fast | custom ]
           Default: client fast. If Amanda does compression of the backup images, it can do so
           either on the backup client host before it crosses the network or on the tape server
           host as it goes from the network into the holding disk or to tape. Which place to do
           compression (if at all) depends on how well the dump image usually compresses, the
           speed and load on the client or server, network capacity, holding disk capacity,
           availability of tape hardware compression, etc.

           For either type of compression, Amanda also allows the selection of three styles of
           compression.  best is the best compression available, often at the expense of CPU
           overhead.  fast is often not as good a compression as best, but usually less CPU
           overhead. Or to specify custom to use your own compression method. (See dumptype
           custom-compress in example/amanda.conf for reference)

           So the compress options line may be one of:

           compress none

           compress client fast

           compress client best

           compress client custom
               Specify client-custom-compress "PROG"

               PROG must not contain white space and it must accept -d for uncompress.

           compress server fast

           compress server best

           compress server custom
               Specify server-custom-compress "PROG"

               PROG must not contain white space and it must accept -d for uncompress.

           Note that some tape devices do compression and this option has nothing to do with
           whether that is used. If hardware compression is used (usually via a particular tape
           device name or mt option), Amanda (software) compression should be disabled.

       client-custom-compress string
           Default: none. The program to use to perform compression/decompression on the client;
           used with "compress client custom". Must not contain whitespace. Must accept -d to
           uncompress.

       server-custom-compress string
           Default: none. The program to use to perform compression/decompression on the server;
           used with "compress server custom". Must not contain whitespace. Must accept -d to
           uncompress.

       dumpcycle int
           Default: 10 days. The number of days in the backup cycle. Each disk using this set of
           options will get a full backup at least this of ten. Setting this to zero tries to do
           a full backup each run.

       encrypt [ none | client | server ]
           Default: not set. To encrypt backup images, it can do so either on the backup client
           host before it crosses the network or on the tape server host as it goes from the
           network into the holding disk or to tape.

           So the encrypt options line may be one of:

           encrypt none

           encrypt client
               Specify client-encrypt "PROG"

               PROG must not contain white space.

               Specify client-decrypt-option "decryption-parameter" Default: "-d"

               decryption-parameter must not contain white space.

               (See dumptype client-encrypt-nocomp in example/amanda.conf for reference)

           encrypt server
               Specify server-encrypt "PROG"

               PROG must not contain white space.

               Specify server-decrypt-option "decryption-parameter" Default: "-d"

               decryption-parameter must not contain white space.

               (See dumptype server-encrypt-fast in example/amanda.conf for reference)

           Note that current logic assumes compression then encryption during backup(thus decrypt
           then uncompress during restore). So specifying client-encryption AND
           server-compression is not supported.  amcrypt which is a wrapper of aespipe is
           provided as a reference symmetric encryption program.

       client-encrypt string
           Default: none. The program to use to perform encryption/decryption on the client; used
           with "encrypt client". Must not contain whitespace.

       client-decrypt-option string
           Default: -d. The option that can be passed to client-encrypt to make it decrypt
           instead. Must not contain whitespace.

       server-encrypt string
           Default: none. The program to use to perform encryption/decryption on the server; used
           with "encrypt server". Must not contain whitespace.

       server-decrypt-option string
           Default: -d. The option that can be passed to server-encrypt to make it decrypt
           instead. Must not contain whitespace.

       estimate [ client | calcsize | server ]+
           Default: client. Determine the way Amanda estimates the size of each DLE before
           beginning a backup. This is a list of acceptable estimate methods, and Amanda applies
           the first method supported by the application. The methods are:

           client
               Use the same program as the dumping program. This is the most accurate method to
               do estimates, but it can take a long time.

           calcsize
               Use a faster program to do estimates, but the result is less accurate.

           server
               Use only statistics from the previous few runs to give an estimate. This very
               quick, but the result is not accurate if your disk usage changes from day to day.
               If this method is specified, but the server does not have enough data to make an
               estimate, then the option is internally moved to the end of the list, thereby
               preferring 'client' or 'calcsize' in this case.

       exclude [ list | file ][[optional][append][ string ]+]
           Default: file. Exclude is the opposite of include and specifies files that will be
           excluded from the backup. The format of the exclude expressions depends on the
           application, and some applications do not support excluding files at all.

           There are two exclude parameters, exclude file and exclude list.  With exclude file,
           the string is an exclude expression. With exclude list , the string is a file name on
           the client containing GNU-tar exclude expressions. The path to the specified exclude
           list file, if present (see description of 'optional' below), must be readable by the
           Amanda user.

           All exclude expressions are concatenated in one file and passed to the application as
           an --exclude-from argument.

           For GNU-tar, exclude expressions must always be specified as relative to the top-level
           directory of the DLE, and must start with "./". See the manpages for individual
           applications for more information on supported exclude expressions.

           With the append keyword, the string is appended to the current list, without it, the
           string overwrites the list.

           If optional is specified for exclude list, then amcheck will not complain if the file
           doesn't exist or is not readable.

           For exclude list, if the file name is relative, the disk name being backed up is
           prepended. So if this is entered:
               exclude list ".amanda.excludes"
           the actual file used would be /var/.amanda.excludes for a backup of /var,
           /usr/local/.amanda.excludes for a backup of /usr/local, and so on.

       holdingdisk [ never | auto | required ]
           Default: auto. Whether a holding disk should be used for these backups or whether they
           should go directly to tape. If the holding disk is a portion of another file system
           that Amanda is backing up, that file system should refer to a dumptype with
           holdingdisk set to never to avoid backing up the holding disk into itself.

           never|no|false|off
               Never use a holdingdisk, the dump will always go directly to tape. There will be
               no dump if you have a tape error.

           auto|yes|true|on
               Use the holding disk, unless there is a problem with the holding disk, the dump
               won't fit there or the medium doesn't require spooling (e.g., VFS device)

           required
               Always dump to holdingdisk, never directly to tape. There will be no dump if it
               doesn't fit on holdingdisk

       ignore boolean
           Default: no. Whether disks associated with this backup type should be backed up or
           not. This option is useful when the disklist file is shared among several
           configurations, some of which should not back up all the listed file systems.

       include [ list | file ][[optional][append][ string ]+]
           Default: file ".". There are two include lists, include file and include list.  With
           include file , the string is a glob expression. With include list , the string is a
           file name on the client containing glob expressions.

           All include expressions are expanded by Amanda, concatenated in one file and passed to
           GNU-tar as a --files-from argument. They must start with "./" and contain no other
           "/".

           Include expressions must always be specified as relative to the head directory of the
           DLE.

               Note
               For globbing to work at all, even the limited single level, the top level
               directory of the DLE must be readable by the Amanda user.
           With the append keyword, the string is appended to the current list, without it, the
           string overwrites the list.

           If optional is specified for include list, then amcheck will not complain if the file
           doesn't exist or is not readable.

           For include list, If the file name is relative, the disk name being backed up is
           prepended.

       index boolean
           Default: no. Whether an index (catalogue) of the backup should be generated and saved
           in indexdir. These catalogues are used by the amrecover utility.

       kencrypt boolean
           Default: no. Whether the backup image should be encrypted by Kerberos as it is sent
           across the network from the backup client host to the tape server host.

       maxdumps int
           Default: 1. The maximum number of backups from a single host that Amanda will attempt
           to run in parallel. See also the main section parameter inparallel.

       maxpromoteday int
           Default: 10000. The maximum number of day for a promotion, set it 0 if you don't want
           promotion, set it to 1 or 2 if your disks get overpromoted.

       max-warnings int
           Default: 20. The maximum number of error lines in the report for a dle. A value of '0'
           means unlimited. This is useful to reduce the size of the log file and the size of the
           report. All errors are put in separate files if a dle have more errors.

       priority [ low | medium | high ]
           Default: medium. When there is no tape to write to, Amanda will do incremental backups
           in priority order to the holding disk. The priority may be high (2), medium (1), low
           (0) or a number of your choice.

       program [ "DUMP" | "GNUTAR" | "APPLICATION" ]
           Default: "DUMP". The type of backup to perform. Valid values are:

           "DUMP"
               The native operating system backup program.

           "GNUTAR"
               To use GNU-tar or to do PC backups using Samba.

           "APPLICATION"
               To use an application, see the application option.

       application string
           No default. Must be the name of an application if program is set to APPLICATION. See
           APPLICATION SECTION below.

       script string
           No default. Must be the name of a script. You can have many script. See SCRIPT SECTION
           below.

       property [append] string string+
           These options can set various properties, they can be used by third party software to
           store information in the configuration file. Both strings are quoted; the first string
           contains the name of the property to set, and the others contains its values.  append
           keyword append the values to the list of values for that property.

       record boolean
           Default: yes. Whether to ask the backup program to update its database (e.g.
           /var/lib/dumpdates for DUMP or /usr/local/var/amanda/gnutar-lists for GNUTAR) of time
           stamps. This is normally enabled for daily backups and turned off for periodic
           archival runs.

       skip-full boolean
           Default: no. If true and planner has scheduled a full backup, these disks will be
           skipped, and full backups should be run off-line on these days. It was reported that
           Amanda only schedules level 1 incrementals in this configuration; this is probably a
           bug.

       skip-incr boolean
           Default: no. If true and planner has scheduled an incremental backup, these disks will
           be skipped.

       ssh-keys string
           Default: not set. The key file the ssh auth will use, it must be the private key. If
           this parameter is not specified, then the default ssh key will be used.

       starttime int
           Default: not set. Backup of these disks will not start until after this time of day.
           The value should be hh*100+mm, e.g. 6:30PM (18:30) would be entered as 1830.

       strategy [ standard | nofull | noinc | skip | incronly ]
           Default: standard. Strategy to use when planning what level of backup to run next.
           Values are:

           standard
               The standard Amanda schedule.

           nofull
               Never do full backups, only level 1 incrementals.

           noinc
               Never do incremental backups, only full dumps.

           skip
               Treat this DLE as if it doesn't exist (useful to disable DLEs when sharing the
               disklist file between multiple configurations). Skipped DLEs will not be checked
               or dumped, and will not be matched by disklist expressions.

           incronly
               Only do incremental dumps.  amadmin force should be used to tell Amanda that a
               full dump has been performed off-line, so that it resets to level 1.

       allow-split bool
           Default: true. If true, then dumps with this dumptype can be split on the storage
           media. If false, then the dump will be written in a single file on the media. See
           "Dump Splitting Configuration" below.

       tape-splitsize int
           Deprecated. See "Dump Splitting Configuration" below.

           Default: not set. Split dump file on tape into pieces of a specified size. The default
           unit is Kbytes if it is not specified.

       split-diskbuffer string

           Deprecated. See "Dump Splitting Configuration" below.  Default: not set. When dumping
           a split dump in PORT-WRITE mode (usually meaning "no holding disk"), buffer the split
           chunks to a file in the directory specified by this option.

       fallback-splitsize int
           Deprecated. See "Dump Splitting Configuration" below.

           Default: 10M. This specifies the part size used when no split-diskbuffer is specified,
           or when it is too small or does not exist, and thus the maximum amount of memory
           consumed for in-memory splitting. The default unit is Kbytes if it is not specified.

       recovery-limit [ server | same-host | string ]*
           Default: global value. This parameter overrides the global recovery-limit parameter
           for DLEs of this dumptype.

       dump-limit [ server | same-host ]*
           Default: server. Specify which host can initiate a backup of the dle. With server, the
           server can initiate a backup with the amdump command. With same-host, the client can
           initiate a backup with the amdump_client command.

       The following dumptype entries are predefined by Amanda:
       define dumptype "no-compress" {
           compress none
       }
       define dumptype "compress-fast" {
           compress client fast
       }
       define dumptype "compress-best" {
           compress client best
       }
       define dumptype "srvcompress" {
           compress server fast
       }
       define dumptype "bsd-auth" {
           auth "bsd"
       }
       define dumptype "bsdtcp-auth" {
           auth "bsdtcp"
       }
       define dumptype "no-record" {
           record no
       }
       define dumptype "no-hold" {
           holdingdisk no
       }
       define dumptype "no-full" {
           skip-full yes
       }

       In addition to options in a dumptype section, one or more other dumptype names may be
       supplied as identifiers, which make this dumptype inherit options from other previously
       defined dumptypes. For instance, two sections might be the same except for the record
       option:
       define dumptype "normal" {
           comment "Normal backup, no compression, do indexing"
           no-compress
           index yes
           maxdumps 2
       }
       define dumptype "testing" {
           comment "Test backup, no compression, do indexing, no recording"
           "normal"
           record no
       }

       Amanda provides a dumptype named global in the sample amanda.conf file that all dumptypes
       should reference. This provides an easy place to make changes that will affect every
       dumptype, although you must be careful that every dumptype explicitly inherits from the
       global dumptype - Amanda does not do so automatically.

TAPETYPE SECTION

       The amanda.conf file may define multiple types of tape media and devices. The information
       is entered in a tapetype section, which looks like this in the config file:
       define tapetype "name" {
           tapetype-option tapetype-value
           ...
       }

       The { must appear at the end of a line, and the } on its own line.

       Name is the name of this type of tape medium/device. It is referenced from the tapetype
       option in the main part of the config file.

       The tapetype options and values are:

       comment string
           Default: not set. A comment string describing this set of tape information.

       filemark int
           Default: 1 kbytes. How large a file mark (tape mark) is, measured in kbytes. If the
           size is only known in some linear measurement (e.g. inches), convert it to kbytes
           using the device density.

       length int
           Default: 2000 kbytes. How much data will fit on a tape, expressed in kbytes.

           Note that this value is only used by Amanda to schedule which backups will be run.
           Once the backups start, Amanda will continue to write to a tape until it gets an
           error, regardless of what value is entered for length (but see amanda-devices(7) for
           exceptions).

       blocksize int
           Default: 32 kbytes. How much data will be written in each tape record, expressed in
           kbytes. This is similar to the BLOCK_SIZE device property, but if the blocksize is not
           a multiple of 1024 bytes, then this parameter cannot be used to specify it, and the
           property must be used instead.

       readblocksize int
           Default: 32 kytes How much data will be read in each tape record. This can be used to
           override a device's block size for reads only. This may be useful, for example, in
           reading a tape written with a 256k block size when Amanda is configured to use 128k
           blocks. This unusual feature is not supported by all operating systems and tape
           devices.

           The default unit is Kbytes if it is not specified.

       part-size int
           If this is set to zero (default), then no splitting will take place, and the entire
           dump will fail, if end-of-medium is encountered before the dump is complete, unless
           the device property LEOM is true, and the device can detect EOM. See "Dump Splitting
           Configuration" below.

       part-cache-type [ none | disk | memory ]
           Default: none. When part caching is required, this parameter specifies the type of
           caching that will be used. The options include no caching (none), in which case a
           failed part will cause the entire dump to fail; on-disk caching (disk), for which
           part-cache-dir must be set properly; and in-memory caching (memory), which on most
           systems severely restrains the size of the part that can be written. See "Dump
           Splitting Configuration" below.

       part-cache-dir string
           Default: none. The directory in which part-cache files can be written when caching on
           disk. See "Dump Splitting Configuration" below.

       part-cache-max-size int
           Default: none. The maximum part size to use when caching is in effect. This is used to
           limit the part size when disk or memory space for caching is constrained. This value
           must be greater than zero.

       speed int
           Default: 200 bps. How fast the drive will accept data, in bytes per second. This
           parameter is NOT currently used by Amanda.

       lbl-templ string
           Default: not set. A PostScript template file used by amreport to generate labels.
           Several sample files are provided with the Amanda sources in the example directory.
           See the amreport(8) man page for more information.

       In addition to options, another tapetype name may be supplied as an identifier, which
       makes this tapetype inherit options from another tapetype. For instance, the only
       difference between a DLT4000 tape drive using Compact-III tapes and one using Compact-IV
       tapes is the length of the tape. So they could be entered as:
       define tapetype "DLT4000-III" {
           comment "DLT4000 tape drives with Compact-III tapes"
           length 12500 mbytes         # 10 Gig tapes with some compression
           filemark 2000 kbytes
           speed 1536 kps
       }
       define tapetype "DLT4000-IV" {
           "DLT4000-III"
           comment "DLT4000 tape drives with Compact-IV tapes"
           length 25000 mbytes         # 20 Gig tapes with some compression
       }

INTERFACE SECTION

       The amanda.conf file may define multiple types of network interfaces. The information is
       entered in an interface section, which looks like this:
       define interface "name" {
           interface-option interface-value
           ...
       }

       The { must appear at the end of a line, and the } on its own line.

       name is the name of this type of network interface. It is referenced from the disklist
       file.

       Note that these sections define network interface characteristics, not the actual
       interface that will be used. Nor do they impose limits on the bandwidth that will actually
       be taken up by Amanda. Amanda computes the estimated bandwidth each file system backup
       will take based on the estimated size and time, then compares that plus any other running
       backups with the limit as another of the criteria when deciding whether to start the
       backup. Once a backup starts, Amanda will use as much of the network as it can leaving
       throttling up to the operating system and network hardware.

       The interface options and values are:

       comment string
           Default: not set. A comment string describing this set of network information.

       use int
           Default: 80000 Kbps. The speed of the interface in Kbytes per second.

       In addition to options, another interface name may be supplied as an identifier, which
       makes this interface inherit options from another interface. At the moment, this is of
       little use.

APPLICATION SECTION

       The amanda.conf file may define multiple types of application. The information is entered
       in a application section, which looks like this:
       define application "name" {
           application-option application-value
           ...
       }

       The { must appear at the end of a line, and the } on its own line.

       name is the name of this type of application. It is referenced from the dumptype

       The application options and values are:

       client-name string
           No default, specifies an application name that is in the amanda-client.conf on the
           client. The setting from that application will be merged with the current application.
           If client-name is set then it is an error if that application is not defined on the
           client.

           If client-name is not set then the merge is done with the application that have the
           name equal to the plugin. eg. if the plugin is 'amgtar', then the setting from the
           application 'amgtar' is used if it is defined.

       comment string
           Default: not set. A comment string describing this application.

       plugin string
           No default. Must be set to the name of the program. This program must be in the
           $libexecdir/amanda/application directory on the client.

       property [append] [priority] string string+
           No default. You can set property for the application, each application have a
           different set of property. Both strings are quoted; the first string contains the name
           of the property to set, and the others contains its values.  append keyword append the
           values to the list of values for that property.  priority keyword disallow the setting
           of that property on the client.

SCRIPT SECTION

       The amanda.conf file may define multiple types of script. The information is entered in a
       script section, which looks like this:
       define script "name" {
           script-option script-value
           ...
       }

       The { must appear at the end of a line, and the } on its own line.

       name is the name of this type of script. It is referenced from the dumptype

       The script options and values are:

       client-name string
           No default, specifies a script name that is in the amanda-client.conf on the client.
           The setting from that script will be merged with the currect script. If client-name is
           set then it is an error if that script is not defined on the client.

           If client-name is not set then the merge is done with the script that have the name
           equal to the plugin. eg. if the plugin is 'amlog-script', then the setting from the
           script 'amlog-script' is used.

       comment string
           Default: not set. A comment string describing this script.

       plugin string
           No default. Must be set to the name of the program. This program must be in the
           $libexecdir/amanda/application directory on the client and/or server.

       order int
           Default: 5000. Scripts are executed in that order, it is useful if you have many
           scripts and they must be executed in a spefific order.

       single-execution boolean
           Default: no. The script is executed for each dle. If yes, the script is executed one
           time only.

       execute-where [ client | server ]
           Default: client. Where the script must be executed, on the client or server.

       execute-on execute_on [,execute_on]*
           No default. When the script must be executed, you can specify many of them:

           script --post-recover

       property [append] [priority] string string+
           No default. You can set property for the script, each script have a different set of
           property. Both strings are quoted; the first string contains the name of the property
           to set, and the others contains its values.  append keyword append the values to the
           list of values for that property.  priority keyword disallow the setting of that
           property on the client.

DEVICE SECTION

       Backend storage devices are specified in amanda.conf in the form of "device" sections,
       which look like this:
       define device name {
           commend "comment (optional)"
           tapedev "device-specifier"
           device-property "prop-name" "prop-value"
           ...
       }

       The { must appear at the end of a line, and the } on its own line.

       name is the user-specified name of this device. It is referenced from the global tapedev
       parameter. The device-specifier specifies the device name to use; see amanda-devices(7).
       As with most sections, the comment parmeter is optional and only for the user's
       convenience.

       An arbitrary number of device-property parameters can be specified. Again, see amanda-
       devices(7) for information on device properties.

CHANGER SECTION

       Changers are described in amanda.conf in the form of "changer" sections, which look like
       this:
       define changer name {
           comment "comment (optional)"
           tpchanger "changer-spec"
           changerdev "device-name"
           changerfile "state-file"
           ...
       }

       The { must appear at the end of a line, and the } on its own line.

       name is the user-specified name of this device. The remaining parameters are specific to
       the changer type selected.

       See amanda-changers(7) for more information on configuring changers.

INTERACTIVITY SECTION

       The amanda.conf file may define multiple interactivyt methods, although only one will be
       used - that specified by the interactivity parameter. The information is entered in a
       interactivity section, which looks like this:
       define interactivity name {
           interactivity-option interactivity-value
           ...
       }

       The { must appear at the end of a line, and the } on its own line.

       name is the user-specified name of this interactivity. The remaining parameters are
       specific to the interactivity type selected.

       The interactivity options and values are:

       comment string
           Default: not set. A comment string describing this interactivity.

       plugin string
           No default. Must be set to the name of the interactivity module, as described in
           amanda-interactivity(7).

       property [append] string string+
           No default. You can set arbitrary properties for the interactivity. Each interactivity
           module has a different set of properties. The first string contains the name of the
           property to set, and the others contains its values. All strings should be quoted. The
           append keyword appends the given values to an existing list of values for that
           property.

       See amanda-interactivity(7) for more information on configuring interactivity methods.

TAPERSCAN SECTION

       The amanda.conf file may define multiple taperscan methods, although only one will be used
       - that specified by the taperscan parameter. The information is entered in a taperscan
       section, which looks like this:
       define taperscan name {
           taperscan-option taperscan-value
           ...
       }

       The { must appear at the end of a line, and the } on its own line.

       name is the user-specified name of this taperscan. The remaining parameters are specific
       to the taperscan type selected.

       The taperscan options and values are:

       comment string
           Default: not set. A comment string describing this taperscan.

       plugin string
           No default. Must be set to the name of the taperscan module. See amanda-taperscan(7)
           for a list of defined taperscan modules.

       property [append] string string+
           No default. Operates just like properties for interactivity methods, above.

       See amanda-taperscan(7) for more information on configuring taperscan.

DUMP SPLITTING CONFIGURATION

       Amanda can "split" dumps into parts while writing them to storage media. This allows
       Amanda to recover gracefully from a failure while writing a part to a volume, by simply
       selecting a new volume and re-writing the dump from the beginning of the failed part.
       Parts also allow Amanda to seek directly to the required data, although this functionality
       is not yet used.

       In order to support re-writing from the beginning of a failed part, Amanda must have
       access to the contents of the part after it has been partially written. If the dump is
       being read from holding disk, then the part contents are availble there. Otherwise, the
       part must be cached, and this can be done memory or on disk. In either of the latter
       cases, the cache must have enough space to hold an entire part.

       Because it is common for a single Amanda configuration to use both holding-disk
       (FILE-WRITE) and direct (known as PORT-WRITE) dumps, Amanda allows the configuration of
       different split sizes for the two cases. This allows, for example, for a part size
       appropriate to large tapes when performing FILE-WRITE dumps, with a part size limited by
       available disk or memory when performing PORT-WRITE dumps.

       Selecting a proper split size is a delicate matter. If the parts are too large,
       substantial storage space may be wasted in failed parts. If too small, large dumps will be
       split into innumerable tiny dumpfiles, adding to restoration complexity; furthermore, an
       excess of filemarks will cause slower tape drive operation and reduce the usable space on
       tape. A good rule of thumb is 1/10 of the size of a volume of storage media.

       In versions of Amanda through 3.1.*, splitting was controlled by the dumptype parameters
       tape-splitsize, split-diskbuffer, and fallback-splitsize. These keywords had confusing and
       non-intuitive interactions, and have since been deprecated.

       If the deprecated keywords are not present, subsequent versions of Amanda use the dumptype
       parameter allow-split to control whether a DLE can be split, and the tapetype parameters
       part-size, part-cache-type, part-cache-dir, and part-cache-max-size. The part-size
       specifies the "normal" part size, while the part-cache-* parameters describe how to behave
       when caching is required (on PORT-WRITE). Full details on these parameters are given
       above.
