To restore backup data in units of Information Stores (Exchange Server 2010 or Exchange Server
2013):
drmexgrestore backup-ID -resync
[ -target Information-Store-name, | -f target-definition-file-name ]
[ -force ] [ -recovery ]
[ -pf copy-parameter-definition-file ]
[ -vf VSS-definition-file-name]

Description
The drmexgrestore command performs from the secondary volume, use disk resynchronization to
restore the backup data specified by the backup ID to the primary volume.
When restoring the results of the VSS backup, the Protection Manager service must be running on the
backup server.
If a database comprises several volumes, all volumes will be restored in order.
The following explains the command processing for restoration in a non-cluster configuration.
1. If the restored database was mounted, the database will be unmounted automatically.
If the unmount of the file system fails, an error message will be displayed, and restoration pro-
cessing error occurs.
2. After the database is stopped properly, and the file system confirms that unmount was successful,
the backup data will be restored from the secondary volume to the primary volume by disk resyn-
chronization.
3. If the file system was unmounted in step 1, the file system will be mounted.
If the file system was already unmounted in step 1, the file system will not be mounted.
4. The database unmounted in step 1 will be mounted.
The following explains the command processing for restoration in a cluster configuration. For this type
of restoration, the cluster group containing the storage groups to be restored must be online. If
restoration is performed while the cluster group is not online, a restoration error occurs. Because the
cluster resources containing the storage groups are offline after restoration, the restored storage groups
are temporarily unusable.
1. The disk resources for the storage groups to be restored are automatically set offline.
If one or more cluster resources depend on a disk resource that is set offline here, these cluster
resources are also set offline automatically. If the command is unable to set the disk resources
offline, it outputs an error message and a restoration processing error occurs.
2. The command verifies that the disk resources have been normally set offline, and then restores
backup data from the secondary volume to the primary volume by resynchronizing the disk.
3. The disk resources are set online.
If one or more cluster resources have been set offline together with the disk resources, these cluster
resources are also set online here.
If ONLINE is set in CLU_MSCS_RESTORE in the Application Agent configuration definition file
(init.conf), restoration can be performed while the cluster resources are online.
In restoration, data on the primary volume is overwritten by the disk image of the secondary volume
at the time backup is performed. Therefore, data on the primary volume that was created or updated
after the backup is invalid.
