HP XP Racks - Manual (Page 377)

• On Exchange 2010 (which does not use storage groups), all information to be backed up must
be mounted in advance.
• You cannot back up storage groups extending across multiple database servers.
• The recovery storage groups for Exchange Server 2003/2007 cannot be backed up. The files
and folders that make up the restoration storage group must be placed on a different file system
from the storage groups to be backed up.
• 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 oper-
ation will result in an error.
• The operations shown below change information pertaining to the Exchange 2003/2007 Server
on the Active Directory, so if you perform any of these operations you will no longer be able to
restore backup data obtained before these operations:
• Modification of the paths of the information store, log, and system files.
• Addition or deletion of storage groups.
• Modification of the storage group name.
• Addition of an information store to a storage group.
• Deletion of an information store from a storage group.
If you have performed any of the above operations, you will need to back up the Active Directory
and the Exchange database again. To perform a backup of the Active Directory database, follow
the instructions in the Microsoft documentation.
• The following event log messages might be output to a backup server:
Event type: Error
Event source: PlugPlayManager
Event ID: 12
Event type: Warning
Event source: ftdisk
Event ID: 57
Event type: Warning
Event source: disk
Event ID: 51
Event type: Warning
Event source: ntfs
Event ID: 50
These messages are displayed because the secondary volume is temporarily hidden during the
backup. They have no impact on the operation and can be ignored.
• When an Exchange replica is created, the following event logs, which do not affect backup pro-
cessing, may be output to the backup server:
Source: VDS Dynamic Provider
Event ID: 10
Level: Error
Description: The provider failed while storing notifications
from the driver. The Virtual Disk Service should be restarted.
