When adding a new database to the storage group, a full backup is required, which can be
accomplished by an express full backup or a consistency check. Incremental backups will fail until
a full backup is completed.
Dismounting Databases
When a database that belongs to a protected storage group is dismounted, protection jobs for
that database only will fail. Logs for that storage group will not be truncated. However, the longer
that the database remains dismounted, the more likely it is that the log space on the Microsoft
Exchange server will overflow, which will result in the dismount of the storage group on the
Exchange server. If the database will not be needed, you should delete it.
Changing the Path of a Database or Log File
If a protected database or log files are moved to a volume that contains data that is protected by
Data Protection Manager (DPM), protection continues. If a protected database or log files are
moved to a volume that is not protected by DPM, DPM displays an alert and protection jobs will
fail. To resolve the alert, in the alert details, click the Modify protection job link and then run a
consistency check.
If a recovery point is created after the path changes, you cannot recover the storage group or
recovery points from recovery points based on the old path. You can still recover data to a
network folder.
If you recover a Microsoft Exchange 2003 storage group after the path for databases or log files
has changed and the most recent recovery point was created before the path change, the
recovery copies the files to the old path and tries to mount the databases. If the databases can be
mounted, the recovery appears to succeed.
If this occurs, you can take one of the following actions:
• Change the databases back to the original path and then recover the storage group again.
• Recover the databases using the Copy to a network folder option. Specify the new location
of the databases as the copy destination. Select the Bring database to a clean shutdown
after copying the files option. Mount the database after recovery.
If you recover an Exchange 2007 storage group after the path for databases or log files has
changed and the most recent recovery point was created before the path changed, DPM will
recover the databases to the new location.
When you change the path of log files for a storage group that uses disk-to-tape backup and only
incremental backups have been performed since the path change, recovery of a storage group
using Latest as the recovery point will fail. To avoid this issue, perform one of the following
actions:
• Run a full backup and then retry the storage group recovery.
• Recover individual databases, rather than the storage group.
• Recover the storage group to a network folder as files.
