Marking Backups as Available or Unavailable

If one or more specific backups are unavailable because of a temporary condition, such as a disk drive that is temporarily offline or a tape stored offsite, then you can mark those backups as unavailable. RMAN does not use unavailable backups to restore or recover data.

RMAN keeps the record of unavailable backups in the RMAN repository and does not delete backups listed as unavailable when you delete expired backups. If the unavailable backups become accessible again, then you can mark them as available.

To mark backups as available or unavailable:

1. On the Database Home page, click Availability to display the Availability subpage.

2. In the Manage section, click Manage Current Backups.

   The Manage Current Backups page appears.

3. In the Search section, find the backups whose status you want to change.

4. Click the Select check box next to each backup in the Results list of backups for which you want to change its availability.

5. Do one of the following:

   • Select Change to Available.

   • Select Change to Unavailable.

   Note: If you restricted the backups listed by searching only for available backups, then only the Change to Unavailable button appears. If you restricted the backups listed by searching only for unavailable backups, then only the Change to Available button appears.

   A confirmation message appears.

6. Click Yes to perform the change operation.
