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] [-help]
vos backup -i <volume name or ID> [-c<cell name>]
[-n] [-l] [-v] [-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.
-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".
