backup_addvolset - Creates a new (empty) volume set
<volume set name
<volume set name
> [ -t
The backup addvolset
command creates a new volume set, by default adding
it to the Backup Database. It is best that the volume set's name indicate the
volume set's contents; for example, define the volume entries in the
"user" volume set to match all user volumes. The volume set name
must be unique within the Backup Database of the local cell.
After issuing this command, issue the backup addvolentry
define the volume entries in the volume set.
Sometimes it is convenient to create volume sets without recording them
permanently in the Backup Database, for example when using the backup
command to restore a group of volumes that were not
necessarily backed up together. To create a temporary
include the -temporary
flag. A temporary volume set exists only during
the lifetime of the current interactive session, so the flag is effective only
when used during an interactive session (opened by issuing the backup
command). If it is included when the command is issued at the
regular command shell prompt, the command appears to succeed, but the volume
set is not created. As noted, a temporary volume set ceases to exist when the
current interactive session ends, or use the backup delvolset
to delete it before that.
One advantage of temporary volume sets is that the backup addvolset
command, and any backup addvolentry
commands subsequently used to add
volume entries to it, complete more quickly than for regular volume sets,
because no records are created in the Backup Database.
- -name <volume set name>
- Names the new volume set. The name can include up to 31 of
any character other than the period. Avoid other metacharacters as
- Creates a volume set that exists only within the context of
the current interactive session. It is not added to the Backup
- Constructs a server ticket using a key from the local
/etc/openafs/server/KeyFile file. The backup command
interpreter presents it to the Backup Server, Volume Server and VL Server
during mutual authentication. Do not combine this flag with the
-cell argument. For more details, see backup(8).
- -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
- Prints the online help for this command. All other valid
options are ignored.
The following command creates a volume set called "sys":
% backup addvolset sys
The issuer must be listed in the /etc/openafs/server/UserList
every machine where the Backup Server is running, or must be logged onto a
server machine as the local superuser "root" if the
flag is included.
