VOS_BACKUP(1) AFS Command Reference VOS_BACKUP(1)NAMEvos_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] [-help]
vos backup -i <volume name or ID> [-c <cell name>]
[-noa] [-l] [-v] [-e] [-nor] [-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
/usr/afs/etc/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.
-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 /usr/afs/etc/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".
