Manual Reference Pages - VOS_BACKUP (1)
vos_backup - Creates a backup volume for a single read/write volume
vos backup -id <volume name or ID>
[-cell <cell name>]
[-noauth] [-localauth] [-verbose]
[-encrypt] [-noresolve] [-help]
vos backup -i <volume name or ID> [-c <cell name>]
[-noa] [-l] [-v] [-e] [-nor] [-h]
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 volumes name is the same as the read/write sources
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
-id <volume name or ID>
Specifies either the complete name or volume ID number of the read/write
-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).
Assigns the unprivileged identity anonymous to the issuer. Do not combine
this flag with the -localauth flag. For more details, see vos(1).
Constructs a server ticket using a key from the local
/usr/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).

execution. If this argument is omitted, only warnings and error messages

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.

The issuer must be listed in the /usr/local/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.
