Restore a file system to the source

The restore function reverts production data to a specified point in time. You can restore a local file system, mapped NFS file system, or mapped SMB file system to its original host, overwriting the existing file system.

File system restoration

When you restore a file system, the backup/recovery appliance:

• Replaces any files on the production disk with the version from the backup image.
• Adds to the production disk any files that are in the backup image, even if they are no longer on the production disk.
• Leaves in place any files on the production disk that are not in the backup image.

In rare cases in which the production data resides on a disk or on an external storage pool presented by the backup/recovery appliance, restores replace the entire volume/block device, so the filesystem reverts to exactly what it was at the time of backup: any files on the production disk that are not in the backup image will no longer be on the production disk after restore.

The amount of time required to complete a restore operation depends on the amount of data involved.

Restore a file system

Use these instructions to restore a file system from a backup image.

1. Click App Manager and select Applications from the drop-down menu.

   The Applications page opens.

2. Select the image that you want to restore, and then choose Access from the drop-down list at the bottom of the Applications page.

   The Access page opens listing captured images in the timeline ramp view. For more information on the view, see Access the timeline ramp view of an image.

   Note: If you are restoring an NFS image, the Advanced NFS Settings must only be changed after consulting with your support representative.

   A warning dialog opens.

3. Read it and then enter DATA LOSS to confirm.

4. Depending on your configuration, a second warning may appear. If so, you need to enter OVERWRITE OTHER APPS to confirm the restore operation.

   The restore job starts. You can verify that the restore operation is successful by viewing the job status in Monitor.

Restore a mapped SMB file system

Use these instructions to restore a point-in-time mapped SMB file system image.

1. Click App Manager and select Applications from the drop-down menu.

   The Applications page opens.

2. Select the mapped image that you want to restore.

3. Choose Access from the drop-down list.

   The Access page opens listing captured images appear in the timeline ramp view. For more information on the view, see Access the timeline ramp view of an image.

4. Select an image, then select Restore from the list of access operations.

   The Restore page opens.

5. Select a single volume or multiple volumes to restore. By default all volumes are selected.

6. Click Submit.

   A warning dialog appears.

7. Read the dialog and enter DATA LOSS to confirm.

8. Depending on your configuration, a second warning may appear. If so, you need to enter OVERWRITE OTHER APPS to confirm the restore operation.

   The restore job starts. You can verify that the restore operation is successful by viewing the job status in Monitor.

   Note: If you need a different username or password to access the SMB share during restore than was used during data capture—perhaps you had to change the password between the captured and restore process—you can click Details & Settings and modify the application-specific settings to add a new username or password—see Configure application settings for file systems).

Restore a mapped NFS file system

Use these instructions to restore a mapped NFS file system image.

1. Click App Manager and select Applications from the drop-down menu.

   The Applications page opens.

2. Select the mapped NFS image that you want to restore, and then choose Access from the drop-down list at the bottom of the Applications page.

   The Access page opens listing captured images appear in the timeline ramp view. For more information on the view, see Access the timeline ramp view of an image.

3. Select an image and then select Restore from the list of access operations.

   The Restore page opens.

4. Select a single volume or multiple volumes to restore. By default all volumes are selected.

5. Click Submit. A warning dialog appears.

6. Read the dialog and enter DATA LOSS to confirm.

7. Depending on your configuration, a second warning may appear. If so, you must enter OVERWRITE OTHER APPS to confirm the restore operation.

   The restore job starts. You can verify that the restore operation is successful by viewing the job status in Monitor.
