Backup3G/DA-RMAN/User Guide/Searching and Restoring Oracle RMAN Backups

From Documentation

Backup3G’s Recovery module lists all the current backups in the media database, including Oracle/RMAN backups.

Searching Oracle/RMAN Backups

You use the backup3G Recovery module to search for and restore from Oracle backups. You can open a media set to view its contents and restore all or selected files.

To launch the Recovery module

From the backup3G button bar (GUI)

• Select the Recover button.

From the backup3G main menu (CUI)

• Select Recovery from backups from the backup3G main menu.

Selecting Oracle Backups to Restore

Caution

Don’t restore files to an online database. Only restore files to an offline database to ensure that database integrity will be maintained.

Target Host and Directory

Some backup3G users have restrictions on which hosts and directories they can restore to (see Restricting Recovery Destinations by Role in the backup3G User Guide for more details). For example users with the Operator role may be restricted to restoring files to the /tmp directory on any host, and to any directory on host ‘playpen’.

If you have any such restrictions, backup3G will ask to choose a target host and directory from the list of permitted destinations. If you have no restrictions you can choose any host and directory in the ‘Recovery Details’ prompt form.

To Restore from an Oracle Backup

1. From the Recovery module, select the media set containing the backup to be restored.
2. Select Contents > Open to list the contents of the media set. Each file in the media set corresponds to an item in the backup job.
3. Select the files to restore:

   To select a file                        - click on it.

   To select several files              - click and drag from the first file down to the last.

   To add a file to the selection   - Control-click on it.

   To extend the selection           - Shift-click on another file.

   To select all files                      - press Control-Shift-Button1

4. Select Recover > Background.
5. If you have any recovery restrictions, backup3G will list which directories and hosts you can restore to. Choose a destination.
   If you have no restrictions, this step is skipped.
6. Fill in these fields in the ‘Recovery Details’ prompt form.

   Recover to host

   Select the name of the host to which the files should be restored. The default is the original host.

   Into directory

   Specify where the restored files should go. The target directory will be created if it doesn’t already exist.

   When you restore the backup files, any existing files of the same name in the target directory will be overwritten. Therefore, it is best to restore to a temporary directory first.

   Drive/Pool

   Press Choose to see the list of valid drives and drive pools.

   Choose a drive and press Accept.

   Auto unload

   Select ‘yes’ to unload the backup tape from the drive after the recovery has finished.
