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

• The recovery storage groups for Exchange Server 2003 cannot be backed up. Allocate files and
folders that comprise a recovery storage group to a file system (drive or mount point directory) of
a disk group different from a storage group subject to backup.
• Dynamic disks cannot be used in Exchange Server 2007 or Exchange Server 2010, in which VSS
is necessary for backup processing, because dynamic disks do not support the use of VSS.
Using a cluster configuration
• Do not register the instances of multiple Exchange resources into a cluster group.
• When using VSS, the following conditions must be satisfied regarding the relationship between
the cluster resource and the Exchange Information Store resource to be operated:
For Exchange Server 2003:
Except for the relationship between the cluster resource and the Exchange System Attendant
resource to be operated, do not set the Exchange Information Store resource to go offline
when a cluster resource goes offline.
For Exchange Server 2007:
Do not set the Exchange Information Store resource to go offline when the cluster resource to
be operated goes offline.
Using the Veritas Cluster Server for Windows configuration
• The status of the cluster resource groups must be online during backup. If it is not online, the backup
command (drmexgbackup or EX_DRM_EXG_BACKUP) will end in error.
• The file system that stores registry replication data should not be backed up via Application Agent.
Make sure that you allocate such a file system to a disk group or physical disk that is not subject
to backup.
• Application Agent uses Veritas Cluster Server Enterprise Agent for Microsoft Exchange to manage
the Exchange services and Exchange protocol services. Do not change the default name for the
resource type ExchService and ExchProtocol provided by Veritas Cluster Server Enterprise
Agent for Microsoft Exchange. Veritas Cluster Server Enterprise Agent for Microsoft Exchange is
bundled with Veritas Storage Foundation HA for Windows.
Cluster configuration using the Microsoft Cluster Service
• Among the cluster resource groups, the Exchange System Attendant resource and the Exchange
Information Store resource must be online during backup. If they are not online, the backup com-
mand (drmexgbackup or EX_DRM_EXG_BACKUP) will result in an error.
Cascade configuration
• Backups in an SCC environment are supported.
• Backups must be executed on the active server of a cluster.
• A disk with Remote Copy defined must be registered as a disk resource of the cluster.
• The primary volume of Remote Copy must be connected to the active server.
• The secondary volume of Remote Copy must be connected to the standby server.
• When you concurrently back up at both the local and remote sites, different backup servers must
be used at each site.
• The Protection Manager service must be running at both the local and remote sites.
• When you back up by using VSS, the VSHTCHORCMINST_REMOTE system environment variable
must be set for the backup server at the remote site.
