Restoring a SAP HANA Scale Out Database

A database restore might be necessary when the data area or the log area is damaged, to recover from a logical error or to copy the database.

The SAP HANA software brings the database down before the restore, and brings the database up after the restore completes.

Before You Begin

1. Perform a full backup.

2. If you changed the node order on the pseudo-client, and the master node is no longer the first node, then reconfigure the node order in the pseudo-client. For more information, see Creating a SAP HANA Scale Out Pseudo-Client.

Procedure

1. From the CommCell Browser, expand Client Computers > client > SAP HANA.

2. Right-click the instance, point to All Tasks and then click Browse and Restore.

   The Browse and Restore dialog box appears.

3. On the Time Range tab, select Latest Backup and click View Content.

4. From the Browse window, select the data to restore, and then click Recover All Selected.

   The Restore Options appears.

5. On the General tab, select the destination client and instance:

   1. From the Destination Client list, select the client that the software uses for the restore operation.

   2. Choose the type of restore that you want to perform:

      Recover the database to the most recent state

      1. Select Recover Database To.

      2. Select Most Recent State.

      Recover to a point-in-time

      1. Select Recover Database To.

      2. Select Point In Time.

      3. Select the date and time.

         Note: If the time zone is different on the CommServe computer and client, in the Time Zone box, select the client computer time zone.

      Recover only the data

      To use this option, you must perform the restore by using a full backup.

      If you restore by specifying the internal backup job ID, then you must have the catalog backup available with backint. SAP HANA creates the internal backup ID and the Commvault software displays the value on the Job Details dialog box.

      If you restore by specifying the backup prefix, then you do not have to have the catalog backup available with backint. The Commvault software creates the backup prefix by pre-pending the job ID to the backup prefix. For example, JOB_ID_SNAP.

      1. Select Recover data only.

      2. Select the backup to use for the restore:

         • To restore by specifying the backup prefix, in the Backup prefix box, type the backup prefix for the backup that you want to restore.

           You can view the backup prefix on the Job Details dialog box (General tab, Backup Prefix). For more information, see Viewing Details of a Job.

         • To restore by specifying the internal backup job ID, in the Internal Backup ID box, type the internal backup job ID that you want to restore.

           You can view the SAP HANA internal backup job ID on the Job Details dialog box (General tab, Internal Backup ID). For more information, see Viewing Details of a Job.

   3. To verify that all the backups required for the recovery operation are available, select the Check Access check box.

   4. To initialize the log area after the restore, select the Initialize log area check box.

6. Optional: Restore from a copy precedence.

   You can restore from a backup copy when the backup is not available or is aged.

   For more information about modifying the copy precedence of a storage policy copy, see Copy Precedence.

   1. Click Advanced.

      The Advanced Restore Options dialog box appears.

   2. On the Copy Precedence tab, select the Restore from Copy Precedence number check box, and then enter a copy precedence number.

   3. Click OK.

7. Click OK.
