Restoring storage groups to a primary volume
This section explains how to restore a storage group when backup data has been saved on a secondary
volume. This example restores the data from the secondary volume to the primary volume by
resynchronizing the volumes.
To restore a storage group:
1.
Check the backup ID of the backup data.
To check the backup ID that will be used to restore backup data from a secondary volume to the
primary volume, execute the
drmexgcat
command on the database server.
DBServer> drmexgcat
STORAGEGROUP: STORAGE_1
BACKUP-ID:0000000001 BACKUP-MODE: VSS STORAGEGROUP: STORAGE_1 ORIGINAL-ID:0000000001
START-TIME:2007/06/01 17:45:36 END-TIME: 2007/06/01 17:52:36

:
Confirm the backup target when restoring a database or Information Store related to a storage
group specified for the
-target
option of the restore command.
2.
Create a backup ID record file.
Execute
EX_DRM_BACKUPID_SET
with the backup ID specified to create a backup ID record
file. Use operation ID
Operation_A
.
DBServer > EX_DRM_BACKUPID_SET Operation_A -backup_id 0000000001
3.
Restore the data from the secondary volume to the primary volume.
Execute
EX_DRM_EXG_RESTORE
on the database server to restore the data from the secondary
volume to the primary volume by resynchronizing the volumes.
DBServer > EX_DRM_EXG_RESTORE Operation_A -resync
Specify operation ID
Operation_A
for
EX_DRM_EXG_RESTORE
. Application Agent acquires
the information required for restoration from the operation definition file. Also, Application Agent
acquires the backup ID from the backup ID record file registered in step 2, and restores the data.
Backing up and restoring by using a tape device
This section describes how to back up and restore data by using a tape device. The explanations in
this section use operation examples for Exchange Server 2003.
System configuration
The examples in this section assume the system configuration shown in the following figure: a
single-database-server system is used in this example, but a multi-database-server system can be used
as appropriate.
