System Directory Backup (DIRECTORY)
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. Directory information can be stored when
you back up system or nonsystem volumes. Storing directory information
helps you rebuild your system from backups should it unexpectedly lose
information. To store system directory information, use the DIRECTORY
parameter. All HFS directories on the system are also stored.
The following example will store all files on the system, plus the system
volume set accounting information.
: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
In the above example, the ONVS parameter will also limit @.@.@ to include
only files on the specified volume sets. See "Storing Files From Volume
Sets" in this chapter.
As illustrated above, the DIRECTORY parameter of the STORE command allows
you to back up the system and/or nonsystem volume set directories
(account structure). You may then reload the account structure in the
event of a system disaster by restoring the directory onto the system
from the backup media. You have the added flexibility of backing up the
directories of nonsystem volumes attached to the system as a part of or
as a separate entity from the system. This allows a nonsystem volume
(volume set) to become a separate reliable entity. System supervisor
(OP) or system manager (SM) capability is required to use the DIRECTORY
parameter.
NOTE When using the DIRECTORY parameter, the default file set list is
empty. This allows a backup to be created that contains only
directory accounting information for the system volume set, or for
the specified volume sets.
Here is an example of how to back up the system directory and all other
files along with a nonsystem volume set directory and its files:
:FILE T;DEV=TAPE
:STORE @.@.@;*T;DIRECTORY;ONVS=MPEXL_SYSTEM_VOLUME_SET,NV1
where NV1 is the name of a nonsystem volume set.
