NAME
amadmin - administrative interface to control Amanda backups
SYNOPSIS
amadmin [--version] [--no-default] [--print-source] [--exact-match] [-o configoption...]
config command [command_options...]
DESCRIPTION
Amadmin performs various administrative tasks on the config Amanda configuration.
See the amanda(8) man page for more details about Amanda.
OPTIONS
--version
Print the version and exit.
--no-default
Do not print default values for config and disklist commands.
--print-source
Print where a value is defined for config and disklist commands.
--exact-match
The host and disk are parsed as exact values
COMMANDS
Commands that take a hostname [ disks ] parameter pair operate on all disks in the
disklist(5) for that hostname if no disks are specified. Where hostname is also marked as
being optional, the command operates on all hosts and disks in the disklist(5) when no
hostname is given. Both hostname and disks are match expressions; see amanda-match(7) for
a description.
version
Show the current version and some compile time and runtime parameters. The config
parameter must be present but is ignored.
estimate [ hostname [ disks ]* ]*
Print the server estimate for the dles, each output lines have the following format:
hostname diskname level size
hostname
The quoted hostname
diskname
The quoted diskname
level
The level of the estimate
size
The estimate size in kbytes
force-bump [ hostname [ disks ]* ]+
Force the disks on hostname to bump to a new incremental level during the next Amanda
run.
force-no-bump [ hostname [ disks ]* ]+
Force the disks on hostname to not bump to a new incremental level during the next
Amanda run.
unforce-bump [ hostname [ disks ]* ]+
Undo a previous force-bump or force-no-bump command.
force [ hostname [ disks ]* ]+
Force the disks on hostname to do a full (level 0) backup during the next Amanda run.
force-level-1 [ hostname [ disks ]* ]+
Force the disks on hostname to do a level 1 backup during the next Amanda run.
unforce [ hostname [ disks ]* ]+
Undo a previous force or force-level-1 command.
retention [ tapelabel ... ]
Print the retention for each tapes.
reuse tapelabel [ ... ]
The tapes listed will be available for reuse at their point in the tape cycle.
no-reuse tapelabel [ ... ]
The tapes listed will not be reused when their turn comes up again in the tape cycle.
Note that if this causes the number of reusable tapes to drop below the
amanda.conftapecycle value, Amanda will request new tapes until the count is satisfied
again.
Tape marked no-reuse are available for recovery, marking them no-reuse is a security
to be sure amanda will not overwrite them.
due [ hostname [ disks ]* ]*
Show when the next full dump is due.
find [ --sort hkdlspbfw ] [ hostname [ disks ]* ]*
Display all backups currently on tape or in the holding disk. The storage name, tape
label or holding disk filename, file number, and status are displayed.
The --sort option changes the sort order using the following flags:
h: host name
k: disk name
d: dump timestamp
l: backup level
p: dump part
b: tape label
s: storage name
f: filenum on tape
w: write timestamp
An uppercase letter reverses the sort order for that key. The default sort order is
hkdlspbfw.
holding delete hostname [ disk [ datestamp [ .. ] ] ]
Delete holding files matching the given specification. At least a hostname must be
provided.
holding list [-l] [-d] [ hostname [ disk [ datestamp [ .. ] ] ] ]
List holding files matching the given dump specification, or all holding files if no
specification is provided. See amanda-match(7) for more information on dump
specifications. With '-l', additional information (size, level, and whether the dump
is outdated) is provided. With '-d', only outdated dumps are shown.
An outdated holding file is one which is not required for a restore of the most recent
dump. Note that outdated dumps may still be required for restores at earlier dates.
For example, assume that a DLE had a level 0 on Monday, level 1's Tuesday through
Thursday, and a level 2 on Friday. Then the files required for a restore of Fridays
(the most recent) dump are those from Monday (level 0), Thursday (level 1), and Friday
(level 2). Tuesday and Wednesday's files are outdated.
delete [ hostname [ disks ]* ]+
Delete the specified disks on hostname from the Amanda database.
Note
If you do not also remove the disk from the disklist(5) file, Amanda will treat it
as a new disk during the next run.
tape [ --days <num> ]
Display the tape(s) Amanda expects to write to during the next run. See also
amcheck(8).
bumpsize
Display the current bump threshold parameters, calculated for all backup levels.
balance [ --days <num> ]
Display the distribution of full backups throughout the dump schedule.
export [ hostname [ disks ]* ]*
Convert records from the Amanda database to a text format that may be transmitted to
another Amanda machine and imported.
import
Convert exported records read from standard input to a form Amanda uses and insert
them into the database on this machine.
config
Dump the full internal representation of this config, in text format.
disklist [ hostname [ disks ]* ]*
Display the disklist(5) information for each of the disks on hostname (or all hosts).
Mostly used for debugging.
hosts
Output a list of distinct hosts in the disklist(5), one per line, for easy use in
shell scripts.
dles
Output a list of distinct DLEs in the disklist(5), one per line with host and diskname
separated by a space, for easy use in shell scripts.
info [ hostname [ disks ]* ]*
Display the database record for each of the disks on hostname (or all hosts). Mostly
used for debugging.
-o configoption
See the "CONFIGURATION OVERRIDE" section in amanda(8).
EXAMPLES
Request three specific file systems on machine-a get a full level 0 backup during the next
Amanda run.
$ amadmin daily force machine-a / /var /usr
amadmin: machine-a:/ is set to a forced level 0 tonight.
amadmin: machine-a:/var is set to a forced level 0 tonight.
amadmin: machine-a:/usr is set to a forced level 0 tonight.
Request all file systems on machine-b get a full level 0 backup during the next Amanda
run.
$ amadmin daily force machine-b
amadmin: machine-b:/ is set to a forced level 0 tonight.
amadmin: machine-b:/var is set to a forced level 0 tonight.
amadmin: machine-b:/usr is set to a forced level 0 tonight.
amadmin: machine-b:/home is set to a forced level 0 tonight.
Undo the previous force request for /home on machine-b. The other file systems will still
get a full level 0 backup.
$ amadmin daily unforce machine-b /home
amadmin: force command for machine-b:/home cleared.
Locate backup images of /var from machine-c. The tape or file column displays either a
tape label or a filename depending on whether the image is on tape or is still in the
holding disk. If the image is on tape, the file column tells you which file on the tape
has the image (file number zero is a tape label). This column shows zero and is not
meaningful if the image is still in the holding disk. The status column tells you whether
the backup was successful or had some type of error.
$ amadmin daily find machine-c /var
date host disk lv tape or file file part status
2000-11-09 machine-c /var 0 000110 9 -- OK
2000-11-08 machine-c /var 2 000109 2 -- OK
2000-11-07 machine-c /var 2 /amanda/20001107/machine-c._var.2 0 OK
2000-11-06 machine-c /var 2 000107 2 -- OK
2000-11-05 machine-c /var 2 000106 3 -- OK
2000-11-04 machine-c /var 2 000105 2 -- OK
2000-11-03 machine-c /var 2 000104 2 -- OK
2000-11-02 machine-c /var 2 000103 2 -- OK
2000-11-01 machine-c /var 1 000102 5 -- OK
2000-10-31 machine-c /var 1 000101 3 -- OK
Forget about the /workspace disk on machine-d. If you do not also remove the disk from the
disklist(5) file, Amanda will treat it as a new disk during the next run.
$ amadmin daily delete machine-d /workspace
amadmin: machine-d:/workspace deleted from database.
amadmin: NOTE: you'll have to remove these from the disklist(5) yourself.
Find the next tape Amanda will use (in this case, 123456).
$ amadmin daily tape
The next Amanda run should go onto tape 123456 or a new tape.
Show how well full backups are balanced across the dump cycle. The due-date column is the
day the backups are due for a full backup. #fs shows the number of filesystems doing full
backups that night, and orig KB and out KB show the estimated total size of the backups
before and after any compression, respectively.
The balance column shows how far off that night's backups are from the average size (shown
at the bottom of the balance column). Amanda tries to keep the backups within +/- 5%, but
since the amount of data on each filesystem is always changing, and Amanda will never
delay backups just to rebalance the schedule, it is common for the schedule to fluctuate
by larger percentages. In particular, in the case of a tape or backup failure, a bump will
occur the following night, which will not be smoothed out until the next pass through the
schedule.
The last line also shows an estimate of how many Amanda runs will be made between full
backups for a file system. In the example, a file system will probably have a full backup
done every eight times Amanda is run (e.g. every eight days).
$ amadmin daily balance
