Test Backup and Restore to Tape for Open Storage
These procedures are only for those deployments that include the tape support option. They illustrate how to use the tape library as part of DPX open storage.
For DPX, the tape library is used as tertiary storage for DPX open storage backup instances, which are populated using DPX Block Data Protection. The process is referred to as DPX Archive. Note that DPX Archive is for individual file and device recovery only; DPX Archive cannot be used for BMR recoveries from tape.
This procedure assumes:
A tape library or tape device is connected by SCSI, iSCSI, or Fibre channel to a device server node.
Media changer control is supported.
DPX Archive tapes are in a dedicated media pool.
For this test, use the backup snapshot that was created earlier in the deployment process, as outlined in Chapter 3: Test Backup and Restore. The snapshot must exist before you can archive it to tape.
DPX Archive jobs are generated through the job scheduler. For Block backup to open storage, the DPX job scheduler includes an option to select a DPX Archive destination. Therefore, when scheduling a Block backup to open storage job with DPX Archive, schedule two job schedule elements, one for the backup to open storage server portion of your job and one for the DPX Archive.
To define, save, and run a DPX archive job to media:
Launch the management console from the master server.
Open the Block Backup Wizard by selecting the Backup tab at the top of the window and then selecting Block from the task pane.
In the Task Panel, under Job Tasks, click Block Backup Wizard.
On the Select Source window, expand the display to the node level. Then select the node to back up by clicking it. This must be the same as the backup source used in Test Backup and Restore.
On the Select Destination window, expand the node group containing the storage node to the volume level. Then select a volume as your backup destination. This must be the same as the backup destination used in Test Backup and Restore.
On the Job Options window, on NDMP tab, if NDMP File History Handling is not selected, select it.
On the Save window, enter a job name and select Schedule Job.
In the Job Schedule window, select Once and change the Backup Run time to a time in the near future. Before clicking Apply on the Job Schedule dialog, do the following:
Click the New button.
Select Archive to Media in the Run field on the Schedule tab.
Select the Device Cluster for the DPX Archive portion of your job from the Device Cluster pull-down menu on the Schedule tab.
Select the Media Pool for the DPX Archive portion of your job from the Media Pool pull-down menu on the Schedule tab.
Select all other job schedule fields as needed.
Click Apply.
Complete the job schedule and click OK. Save the job when you have completed the job definition.
Click Finish to close the Block Backup Wizard.
In the task pane, select Run Backup Job. Select the job and click OK. The backup job starts.
Select the Monitor tab to display the progress of the job. When the job has finished, the Job Monitor window says job_name Completed at the upper left.
To restore from media:
Select the Restore tab at the top of the window then selecting Block from the task pane.
In the sources pane, expand the resource tree of the DPX open storage server that you backed up. Then select resources to restore.
In the destination pane, expand the display and select a directory to restore to. If you do not select a restore destination, the files are restored to the original location.
In the task panel, select Save Restore Job. The Save Job dialog box appears.
Name the job and select OK.
In the task panel, select Run Restore Job.
Select the Monitor tab to display the progress of the job.
