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

• In a cluster environment, when restoring data in a physical node different from that used during
backup, an Exchange virtual server that uses the same shared disk as that used during backup
must be running. Application Agent cannot restore data for an Exchange virtual server, such as
one at a remote site, that uses a disk different from the one used during backup.
Using VSS
This section describes requirements and precautions used when VSS is used to back up an Exchange
database.
• The following database products are subject to backup:
• Exchange Server 2003 Enterprise Edition
• Exchange Server 2003 Standard Edition
• Exchange Server 2007 Enterprise Edition
• Exchange Server 2007 Standard Edition
• Exchange Server 2010 Enterprise Edition
• Exchange Server 2010 Standard Edition
• RM Shadow Copy Provider must be installed in advance, on both the database server and the
backup server. If RM Shadow Copy Provider has not been installed on those servers when Applic-
ation Agent is installed, RM Shadow Copy Provider will be installed together with Application
Agent.
• The backup server is required even if data is not backed up to tape. This is because the backup
server imports VS snapshots and verifies the Exchange database.
• If Veritas Snapshot Provider is installed on the database server or backup server where a VSS
backup will be performed, make sure you use version Veritas Snapshot Provider 1.04 or later.
If a VSS backup is executed using version Veritas Snapshot Provider 1.03 or earlier, the volume
to be backed up might be left with Read-Only and Hidden attributes. If this happens, the drive
will not be allocated at system startup and Exchange Server will not operate normally.
If this occurs, release these attributes as described in Microsoft Knowledge Base Article 840781.
Note that, to perform the operations described in Knowledge Base Article 840781, you need to
apply the hotfix described in Microsoft Knowledge Base Article 831112.
If the OS is Windows Server 2003 SP2 or later, you do not need to apply the hotfix described in
Microsoft Knowledge Base Article 840781 and 831112.
• If a system failure or other problem causes a VSS backup to be interrupted, the volume that is the
target of the backup might be left with the Read-Only and Hidden attributes. If these attributes
remain, the drive will not be allocated at system startup, and Exchange Server will not operate
normally. If this occurs, release the attributes as per Microsoft Knowledge Base Article 840781.
Note that, to perform the operations described in Knowledge Base Article 840781, you need to
apply the hotfix described in Microsoft Knowledge Base Article 831112.
If the OS is Windows Server 2003 SP2 or later, you do not need to apply the hotfix described in
Microsoft Knowledge Base Article 840781 and 831112.
• You can acquire backup or delete transaction logs while Exchange Server is operating. However,
you cannot back up data while Exchange Information Store service is shut down.
• During backup, the database write processing of Exchange Server shuts down for a certain period
(up to 10 seconds). During that period, the database write processing of Exchange Server (such
as sending mail) is suspended. After backup finishes, the database write processing of Exchange
Server is resumed.
• Since the number of log files might increase during backup operations by VSS, when you perform
backup by using VSS, the backup results might contain a log file that has not been recorded in
the catalog.
