Figure 62 Correspondence of backup catalog and copy group

When you back up database A only (as in step 2), the backup ID

0000000002

is created, and

the old backup information (backup ID:

0000000001

) about the copy group

VG01,obj01

on

database A is deleted from the backup catalog. In other words, since the backup information
about database B, which is included in the backup ID

0000000001

, is also deleted from the

backup catalog, database B cannot be restored even though the backup data exists in the secondary
volume. When you restore database B, restore the backup data obtained by using step 1 (backing
up database A and database B concurrently) from tape to the secondary volume, and then restore
the backup data from the secondary volume to the primary volume.
If Application Agent commands are executed on volumes that comprise a disk group managed
by Veritas Storage Foundation, the error logs listed below might be output to the Windows event
log. However, this does not indicate a problem. When Application Agent commands terminate
normally, then when the disk group deport processing is executed again, you can verify that it
was successful.
• Event ID in the Windows application event log:

10242

• Event ID in the Veritas Enterprise Administrator event log:

V-76-58645-10243

Precautions on backup

The system cache of the secondary volume must be cleared before executing this command. Execute
the

EX_DRM_CACHE_PURGE

command on the backup server to clear the system cache.

When you execute a backup command for a copy group in the

PAIR

status, the status of the copy

group is changed to

PSUS

. To put the copy group in the

PAIR

status, use the

drmresync

com-

mand.

If you execute a backup command when information about the operation target object is not created
in the dictionary map files, the dictionary map files are created by the command. In this case, the
processing time required to create the dictionary map files is added to the total backup processing
time.

Make sure no other volume is mounted on the directory of the volume to be backed up when
performing an online backup. For details, see

Volume configuration requirements

” on page 91.
