Checking Backups and Restoring Data

Checking Backups Created Automatically or Manually

You can check all backups on the Backups tab, as shown in Figure 1.

Names of backups created automatically start with autobk_ and those created manually start with manualbk_.

For your convenience, backups are also displayed on the Disks tab of your BMS details page.

Restoring Data

When disks on a server are faulty or if their data is lost, you can use a backup to restore the server to the state it was in when the backup was created.

1. Click the Backups tab and locate the desired backup.
2. Click Restore Server in the Operation column, as shown in Figure 3.
   

   • The current server data will be overwritten by the data captured at the time of backup. The restoration cannot be undone.
   • Servers will be shut down during restoration, so perform restorations during off-peak hours.

3. (Optional) Deselect Start the server immediately after restoration.

   In this case, you need to start the server manually after the restoration is complete.

4. In the Destination Disk drop-down list, select the disk that the backup will be restored to.
   

   If there are more disks to be restored than the disks that were backed up, restoration may cause data inconsistency.

   For example, if Oracle data is scattered across multiple disks and only some of the disks are restored, data may become inconsistent and the application may be unable to start.

   

   • If a server has only one disk, the backup is restored to that disk by default.
   • If a server has multiple disks, the backup is restored to the original disks by default. You can restore a backup to a different disk by selecting that disk from the Destination Disk drop-down list. That disk must be at least as large as the original disk.
   • Data on data disks cannot be restored to system disks.
5. Click OK and confirm the restoration was successful.

   In the backup list, check the restoration status. When the backup status changes to Available if there are no new failed restoration tasks in Tasks, you know that the restoration was successful. Data is restored to the state the disk was in when the backup was created.
