Migrating Backup Data to a New NAS File Server

You can migrate the backed-up data of a NAS file server to a new NAS file server.

Procedure

  1. From the navigation pane, go to Protect > File Servers.

    The File servers page appears.

  2. On the upper-right corner of the page, click Add server.

    The Add server page appears.

  3. Click NAS.

    The Add NAS server dialog box appears.

  4. In the Name box, enter a name for the file server.

  5. In the Host name box, enter the fully qualified host name of the file server.

    By default, the Host name is same as the name of the file server.

  6. From the Plan list, select the server plan to use for the new NAS file server.

  7. Under Network share configuration, move the CIFS toggle key to the right.

  8. From the Access node list, select an access node with no archiver driver installed to stage the data for restore operation.

  9. Beside CIFS credentials, click Edit, and then specify the credentials to use.

  10. Beside Content, click Edit, and then enter the path to the data to back up.

  11. Under the Migrate to this server, move the Migrate data from old server toggle key to the right.

    The Migration details dialog box appears.

  12. From the Source server list, select the NAS file server that you want to migrate (the source).

    Note

    The source server list does not display deconfigured clients. If the source server is already selected for migration, it will not be listed until the migration is complete.

  13. For Date and time of cutover, enter the date and time when you want to complete migration, initiate the last phase (migration workflow), and email the cutover approver.

    An email is sent to the cutover approvers to approve or deny the cutover. If the cutover approver denies the cutover, then you must reschedule the Date and time of cutover.

    If the cutover is approved, the following things occur:

    • Data aging on the source server is disabled for 90 days.

    • Backup and archive activity on the source subclient is disabled.

    • Backup activity on the destination subclient is enabled.

      Note

      Once approved, you cannot edit or reschedule the cutover.

  14. In the Cutover approver(s) box, enter the users and user groups that you want to approve the migration.

  15. In the User name and Password boxes, enter the user credentials for the destination NAS shares.

  16. In the Target data starting path box, enter the share name or the volume name, without the server path, where you want to store the migrated source data and source directory structure.

    To configure multiple shares for migration, you need to select a subclient and complete the migration, and then configure migration for the next subclients that you select.

    Note

    Once selected, the path cannot be edited. You might need to cancel the migration and configure once again.

  17. If you do not want to create the backup sets and subclients that the source NAS file server has, then move the Migrate configuration toggle key to the left.

    Under Folders to migrate, select the content to migrate.

  18. Click Save.

What to Do Next

In the Migration status section of the destination NAS file server page, you can do the following:

  • Monitor the progress of the migration.

  • Edit the migration.

    The Edit option allows you to select or deselect content paths for migration. If you deselect all the content paths of a subclient, then the subclient created for migration will have no paths.

    For example, you can modify the date and time of cutover, the cutover approvers, the included and excluded paths for migration.

  • Cancel the migration.

Results

After the migration is complete, the migrated NAS file server data is in the location that you specified in the Target data starting path box, and follows the retention criteria of the source subclient. In case of a Celerra source client, the access control lists (ACLs) of the data are not migrated. On the destination NAS server, the backupset name is appended to the source server name in the following format:\\source_server\backupset.

The subclient created as a part of migration on the destination NAS server has properties such as storage policies, retention and archiving rules similar to that of the source subclients.
