Backing Up MPE Volume Sets

Backing Up MPE Volume Sets
Only system administrators should back up volume sets. A backup of an MPE volume
set takes a snapshot of the volume sets, including the directory information. Having
this information backed-up prepares you for a disaster recovery.
The system administrator should have configured your HP 3000 NetWorker MPE
client to do server-initiated backups of volume sets. Refer to “Configuring the MPE
Client on the NetWorker Server” in the Legato NetWorker ClientPak for MPE/iX
Installation Guide for information on configuring your HP 3000 on a NetWorker server.
In addition to server-initiated backups of MPE volume sets from the NetWorker server,
you can perform manual backups of MPE volume sets from the HP 3000 NetWorker
MPE client.
Naming Conventions for Backing Up MPE Volume Sets
MPE supports two types of volume sets: system volume sets and non-system volume
sets. MPE systems are shipped with a single preconfigured system volume set called
MPEXL_SYSTEM_VOLUME_SET. You can add as many non-system volume sets as
you need.
The naming conventions for each type of volume set are different:
• For both system and non-system volume sets, add a slash (/) before the volume
set name, for example: /MPEXL_SYSTEM_VOLUME_SET.
• For an MPE non-system volume set, append the tag _VOLUME_SET to the end of
the volume set name. For example, if you were backing up or recovering all
project files that reside exclusively on an MPE volume set, PROJECTS, you would
name the volume set /PROJECTS_VOLUME_SET.
Do not append _VOLUME_SET to the end of an MPE system volume set. When an
HP system is installed, it automatically creates the MPE system volume,
MPEXL_SYSTEM_VOLUME_SET.
To perform sever-initiated backups of MPE volume sets, add the correct save set names
for the MPE volume sets to the Client resource on the NetWorker server.
When NetWorker saves an MPE volume set, it saves the directory accounting
information file in the pseudo file, /PROJECTS_VOLUME_SET_DAF.
To recover all the files and directories on an MPE volume set, you use the save set
identification (ssid) for the volume set. See “Recovering Volume Sets” on page 41 for
more information on recovering MPE volume sets.
If the default keyword “All” appears in the Save Set attribute in the Clients resource on
the NetWorker server, all currently mounted MPE volume sets for the MPE client are
backed up according to the group and schedule listed in the Clients resource.
