The system directory keeps track of the accounts,
groups, users, and files in your system. Nonsystem volume set
directories keep track of the contents of nonsystem volumes.
When you back up either type of volume, you should store its
directory information so that you can rebuild your system from backup
tapes in the event of an unexpected data loss.

The DIRECTORY parameter of the STORE
command allows you to back up the account structure and all HFS
directories on system and/or nonsystem volume sets.
You may then reload the account structure and HFS directories
in the event of a system disaster by restoring them onto the
system from the backup media. You have the added flexibility of
backing up the directories of nonsystem volumes as a part of or as a
separate entity from the system. This allows a nonsystem volume to
become a separate reliable entity. System supervisor (OP) or
system manager (SM) capability is required to use the DIRECTORY parameter.
To store directory information on system volumes, use the DIRECTORY
parameter of the STORE command. For example:
FILE T;DEV=TAPE
STORE /;*T;DIRECTORY
|
To store nonsystem volume set directory information, use DIRECTORY
and ONVS in the same command. For example:
FILE T;DEV=TAPE
STORE /;*T;ONVS=VOL_SET_A;DIRECTORY
|
The example below shows how to back up the system directory and all
other files and a nonsystem volume set directory (NV1) and its files:
FILE T;DEV=TAPE
STORE /;*T;DIRECTORY;ONVS=MPEXL_SYSTEM_VOLUME_SET,NV1
