Naming Conventions for Backing Up MPE Volume Sets

MPE supports two types of volume sets: system volume sets and nonsystem volume

sets. MPE systems are shipped with a single preconfigured system volume set called

MPEXL_SYSTEM_VOLUME_SET. You can add as many nonsystem volume sets as

you need.

The naming conventions for each type of volume set differs:

• For both system and nonsystem volume sets, add a slash (/) before the volume set

name, for example: /MPEXL_SYSTEM_VOLUME_SET.

• For an MPE nonsystem volume set, append the tag _VOLUME_SET to the end of

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 server-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. Refer to “Recovering Volume Sets” in

“Chapter 4: Recovering Files” of the Legato NetWorker User’s Guide, MPE/iX Version,

Release 5.5 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.

Listing Groups in an MPE Volume Set

You can get a list of all accounts and groups in an MPE volume set that NetWorker will

back up in a server-initiated backup.

Enter the following MPE command at the CI prompt to display a list of groups in an

MPE volume set:
