NDMP

If you are using an older SEP sesam version, refer to NDMP documentation.

To successfully restore an NDMP backup, make sure that all prerequisites are met and preparation steps are performed. See also NDMP Backup.

How you perform the NDMP restore depends on how you created the backup. For example, if you have created a dump backup (default), you will perform a normal restore. If you have created a smtape backup (supported only by NetApp), you must define additional arguments for smtape restore in the final step of the restore wizard.

SEP sesam version 4.4.3 Grolar supports selective and complete restore from dump backups.

Restoring NAS volume data is simple and straightforward. The basic restore steps are described below.

Prerequisites

  • Make sure that you have required permissions and access rights for NDMP restore.
  • Make sure that there is sufficient free space on the target storage system to which you are restoring your data.

Additional prerequisites for smtape restore

  • Ensure that there is about 100 MB more space on the destination storage system than the amount of data to be restored.
  • The volume to which you are going to restore data must be of type DP (data protection) and must be put in a restricted state prior to executing the restore. See NetApp documentation for more information.
  • smtape restore completely overwrites the destination volume; make sure that there is no critical data stored on the target volume.

Restoring NDMP

For details on how to configure a restore task and a description of different restore options, see Standard Restore Procedure. Only NDMP-specific steps and options are described in this section.

Information sign.png Note
Direct access recovery (DAR) is used during backup to enable selective restore. As of version 4.4.3 Grolar, DAR is enabled by default. If you have disabled it while creating a backup task, you cannot perform a selective restore. For details, see dump backup.

NDMP backups can be restored to the same or a different location. For smtape restore, additional step (step 5) is required to specify the smtape restore type.

  1. From the SEP sesam GUI menu bar, select Activities -> Restore and select the save set you want to restore (type NDMP).
  2. In the Select task step of the wizard, select the desired version from the list of save sets matching your query. If you want to perform a complete restore, select the checkbox complete restore of selected task and click Next. If you want to restore only selected items, click Next.

    3. NDMP select task Grolar.jpg

  3. In the Select files dialog, select the files you want to restore and click Next. This step is not available for complete restore.
  4. In the Save and start step of the wizard, you can choose to restore the NDMP backup data to to the same location by using the Restore to original target path (default) or to a different location by selecting the New restore target option.
    • If you are performing a normal restore (not smtape) and you choose a new restore target, you can restore your data to a volume or subdirectory by entering the target path as follows: /<volume_name>/<target_dir>.
    • If you are performing a smtape restore, the restore destination must be the root of a volume, e.g., /vol/vol1.
  5. This step is required only for smtape restore: Click the button Expert options -> tab Options and enter the following in the Restore options field:
    6. -a ndmp_tape_format=smtape

    NDMP save Grolar.jpg

  6. If you want to start the NDMP restore immediately, click Start. If you want to save the NDMP restore task, click Save.
Information sign.png Note
After performing a smtape restore, the restored volume is in the read-only state. To make the destination volume writable, use the snapmirror break command. See NetApp documentation for more information.

A restore task can be scheduled like any other task. If you want to add the NDMP restore task to the schedule, see Scheduling Restore.

You can view the status of the NDMP restore by selecting Job State -> Restore in the Main selection window. It displays detailed information on the restore operations, including task name, start and stop time of the restore, restore type, data size, throughput, status message, etc.
