Restore an Oracle database from a snapshot

Phoenix Editions: File:/tick.png Business File:/cross.png Enterprise File:/tick.png Elite

 

You can recover databases from the warm snapshots that are stored in the Druva Cloud and cold snapshots stored in the AWS glacier. Druva Phoenix allows you to restore a complete database automatically on your Oracle server host. Druva Phoenix also enables DBAs to manually recover individual database elements, such as data files, control files, system parameter files, archive logs, and metadata. When you restore a complete database from a snapshot back to the original server host, Druva Phoenix overwrites all the existing content of the database. When you choose to recover individual database elements, Druva Phoenix downloads the requested snapshot on the restore location specified during the restore operation. DBA can manually recover the required database elements by running scripts.  For more information, see Recover database from the downloaded backup data.

To restore databases, you select a snapshot or a restore point from the snapshots drop-down list. The list displays the timestamp of all the snapshots available for restore. Based on the requested resource (complete database or individual database elements), Druva Phoenix restores data by overwriting all of the existing content of the database or downloading the backup data to the specified restore location. The DBA can run RMAN commands to fetch backup data downloaded to the restore location and recover the database on the required Oracle server host.

The following video illustrates the process.  

Procedure

  1. Log in to the Phoenix Management Console. 
  2. On the menu bar, click All Organizations, and select the required organization from the drop-down list.
  3. On the menu bar, click Protect > Oracle > Direct to Cloud
  4. In the left navigation pane, click Configured Databases.
  5. On the Configured Databases page, select the database that you want to restore and click Restore.
    Note: To quickly search and select a database, you can use the search box on the top-right corner of the Configured Databases page to filter the listed database. Type the name of the database, Oracle server, or the availability group in the search tab to narrow down on the database that you want to select.
  6. On the Restore Database page, click Snapshot Restore.
  7. Click the timestamp drop-down list to list the available snapshots to restore databases from.
  8. Select the required snapshot, and then in the Database Files section select the database or database elements that you want to restore.|

  9. Click Restore.
    Note: If a backup job for the database selected for snapshot restore is already running, Druva Phoenix prompts a message to cancel the backup job and trigger restore. 
  10. If you selected the database check box, Druva Phoenix provides the following two restore target options to restore the complete database. 
    1. Restore to original Oracle server: Allows you to restore the complete database automatically to the original Oracle server from where it was backed up.

      1. Click Restore to original Oracle server and click Finish
        Druva Phoenix prompts you with a warning message that the original database on your Oracle server will be replaced with the restored data. Click Yes on the confirmation dialog.
        Druva Phoenix terminates connections to the database on the original server host and then replaces the database with the restored database.
    2. Restore database files: Allows you to download the requested database files to the selected server and location. The database needs to be manually recovered on the server. For more details, see Recover database from the downloaded backup data.
      1. In the Destination Server list, select the Oracle server host to download the backup data to. By default, the original Oracle server host is selected where the database was backed up. When you restore a database to its original location, Druva Phoenix replaces the database on the Oracle server host with the restored database. 
      2. In the Restore Location box, browse to the location on the selected server where you want to download the backup data or type the absolute path to the restore location.
      3. Click Finish.
  11. If you selected check box(es) of the individual database element(s) to restore, Druva Phoenix provides only the Restore database files option to download the requested database files to the selected server and location. The database need(s) to be manually recovered on the required server.

    1. In the Destination Server list, select the Oracle server host to download the backup data to. By default, the original Oracle server host is selected where the database was backed up. When you restore a database to its original location, Druva Phoenix replaces the database on the Oracle server host with the restored database. 
    2. In the Restore Location box, browse to the location on the selected server where you want to download the backup data or type the absolute path to the restore location.
    3. Click Finish

The backup database is downloaded to the location you specify. After you click Finish, Druva Phoenix generates a restore job. You can track the progress of the job by viewing the progress log. For more information, see View progress logs.

Next Steps

The DBA can run RMAN scripts to fetch backup data downloaded to the restore location and recover the database on the required Oracle server host. For more information, see Recover database from the downloaded backup data.
