NAME

       vos_backup - Creates a backup volume for a single read/write volume

SYNOPSIS

       vos backup -id <volume name or ID>
           [-cell <cell name>]
           [-noauth] [-localauth] [-verbose]
           [-encrypt] [-noresolve]
           [-config <config directory>]
           [-help]

       vos backup -i <volume name or ID> [-c <cell name>]
           [-noa] [-l] [-v] [-e] [-nor]
           [-co <config directory>]
           [-h]

DESCRIPTION

       The vos backup command clones the indicated read/write volume to create a backup version,
       placing it at the same site as the read/write version. The backup volume's name is the
       same as the read/write source's with the addition of the ".backup" extension. Its volume
       ID number is the one allocated for it in the Volume Location Database (VLDB) when the
       read/write source was created with the vos create command. If a backup version already
       exists, the new clone replaces it.

       To create a backup version of multiple volumes, use the vos backupsys command.

OPTIONS

       -id <volume name or ID>
           Specifies either the complete name or volume ID number of the read/write source
           volume.

       -cell <cell name>
           Names the cell in which to run the command. Do not combine this argument with the
           -localauth flag. For more details, see vos(1).

       -noauth
           Assigns the unprivileged identity "anonymous" to the issuer. Do not combine this flag
           with the -localauth flag. For more details, see vos(1).

       -localauth
           Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile
           file. The vos command interpreter presents it to the Volume Server and Volume Location
           Server during mutual authentication. Do not combine this flag with the -cell argument
           or -noauth flag. For more details, see vos(1).

       -verbose
           Produces on the standard output stream a detailed trace of the command's execution. If
           this argument is omitted, only warnings and error messages appear.

       -encrypt
           Encrypts the command so that the operation's results are not transmitted across the
           network in clear text. This option is available in OpenAFS versions 1.4.11 or later
           and 1.5.60 or later.

       -noresolve
           Shows all servers as IP addresses instead of the DNS name. This is very useful when
           the server address is registered as 127.0.0.1 or when dealing with multi-homed
           servers. This option is available in OpenAFS versions 1.4.8 or later and 1.5.35 or
           later.

       -config <configuration directory>
           Set the location of the configuration directory to be used. This defaults to
           /etc/openafs, except if -localauth is specified, in which case the default is
           /etc/openafs/server. This option allows the use of alternative configuration locations
           for testing purposes.

       -help
           Prints the online help for this command. All other valid options are ignored.

OUTPUT

       The following message confirms that the command succeeded:

          Created backup volume for I<volume name>

EXAMPLES

       The following example creates a backup version of the volume "user.smith".

          % vos backup user.smith
          Created backup volume for user.smith

PRIVILEGE REQUIRED

       The issuer must be listed in the /etc/openafs/server/UserList file on the machine
       specified with the -server argument and on each database server machine. If the -localauth
       flag is included, the issuer must instead be logged on to a server machine as the local
       superuser "root".
