HP StorageWorks P9000 Replication Manager Software 7.1 CLI User Guide (TB584-96026, May 2011)

The objects subject to backup are as follows:
When the backup is of a file system: mount point.
When the backup is of an SQL Server database: database.
When the backup is of an Exchange database: storage group or Information Store.
Figure 61 CorrespondenceCorrespondence 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.
• When using Snapshot, make sure to only back up a single generation. Backups for multiple gen-
erations might fail.
• If Application Agent commands are executed on volumes that comprise a disk group managed
by Veritas Volume Manager, the error logs listed below will be output to the event log, but 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.
