HP Data Protector A.06.00 additional writers and HP StorageWorks Disk Array XP support for Microsoft Volume Shadow Copy Service integration

To avoid the session failing, select the option Revert to active node on failure in the
same dialog box. The backup will be restarted on the original server (active cluster
node) and the original storage group will be backed up. This option is ignored during
backup of an Information Store instance.
Limitations
• In CCR environments, if a replicated storage group (Replication Service instance)
is selected for backup, no other VSS writer (for example, filesystem writer) can
be selected to be backed up in the same backup session. Because in this case,
two writers would be located on different systems, but Data Protector limits VSS
backup sessions to involve only one system.
• In LCR and CCR environments, each storage group can have only one store.
• CCR clusters can have only two nodes.
Considerations
• Transaction log files are truncated after each full or incremental Microsoft Exchange
Server backup. The LCR and CCR clustering technologies, however, guarantee
that logs that have not been replicated are not deleted. Thus, running backups
in a mode that truncates logs may not actually free space. This may happen if
replication of logs has not completed yet.
Microsoft Data Protection Manager 2006 writer specifics
Microsoft Data Protection Manager 2006 (DPM) is a server application that creates
replicas of the clients, synchronizes them through LAN, and stores these replicas as
snapshots.
The Data Protection Manager writer is used to back up:
• the Data Protection Manager database and the Data Protection Manager Report
database
• the latest version of the DPM replicas.
IMPORTANT:
To ensure data consistency, schedule a DPM replica synchronization before starting a
backup.
The DPM uses DPM snapshots for restore. These snapshots are not backed up. To be
able to recreate DPM snapshots you must manually schedule a backup of the replica
each time after the DPM creates a new replica.
