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.
