Duplicating backed up data

You can create a job to duplicate backup data, selecting either to duplicate existing backup sets or to duplicate backup sets immediately following a scheduled job.

If you select to duplicate existing backup sets, the backup sets you select from catalogs are read from the source media and written to the selected destination, such as a drive, drive pool, or backup folder. You can schedule when this type of job runs.

If you duplicate Oracle or DB2 backup sets that were created with multiple data streams, note the following:

If you select to duplicate backup sets following a job, you select a scheduled backup job as the source. That backup job runs first, and then the backup sets it created are copied to the destination you selected for the duplicate job. To duplicate backup sets following a job, the backup job must be scheduled to run and must not be associated with any other duplicate jobs. You cannot schedule this job; instead, the duplicate job runs only after the related, or linked, backup job completes.

To duplicate backup data

  1. From the navigation bar, click Job Setup.

  2. Under Backup Tasks, select New job to duplicate backup sets.

  3. If you want to copy existing backup sets to another destination, do the following in the order listed:

    • Select Duplicate existing backup sets, and then click OK.

    • Select the backup sets you want to copy. For Oracle or DB2 jobs that were created with multiple data streams, under the instance name, select the date on which the backup set was created.

  4. If you want to duplicate backup sets created when a scheduled backup job runs, do the following in the order listed:

    • Select Duplicate backup sets following a job, and then click OK.

    • Select the scheduled backup job to be used as the source.

  5. On the Properties pane, under Destination, select Device and Media.

    See Device and media options for backup jobs and templates.

  6. On the Properties pane, under Settings, click General, and complete the appropriate options as follows:

    Job name

    Type the name for this backup job.

    Job priority

    Select the priority level for this job. If another job is scheduled to run at the same time as this job, the priority you set determines which job runs first.

    Your can choose the following priorities:

    • Highest

    • High

    • Medium

    • Low

    • Lowest

    Backup set description

    Type a description of the information you are backing up.

    Preferred source device

    Select the device used as the destination device for the original backup job.

  7. On the Properties pane, under Settings, click Advanced, and complete the appropriate options as follows:

    Verify after job completes

    Select this option to have Backup Exec automatically perform a verify operation to make sure the media can be read after the backup has been completed. Verifying all backups is recommended.

    Compression type

    Select one of the following:

    • None. Select this option to copy the data to the media in its original form (uncompressed). Using some form of data compression can help expedite backups and preserve storage media space.

      Hardware data compression should not be used in environments where devices that support hardware compression are used interchangeably with devices that do not have that functionality.

      For example, if a drive that does not support hardware compression is added to a cascaded drive pool that includes drives supporting the feature, hardware compression is automatically disabled. You can manually re-enable hardware compression on the drives that support it, but this results in media inconsistency. If the drive that supports hardware compression fails, the compressed media cannot be restored with the non-compression drive.

    • Hardware [if available, otherwise none]. Select this option to use hardware data compression (if the storage device supports it). If the drive does not feature data compression the data is backed up uncompressed.

  8. To encrypt the duplicated data, do the following in the order listed:

    • On the Properties pane, under Settings, click Network and Security.

    • Select an encryption type from the list.

    • Select an encryption key from the list or click Manage keys to create a new key.

  9. If you want Backup Exec to notify someone when the backup job completes, on the Properties pane, under Settings, click Notification.

    See Assigning notification recipients for completed jobs.

  10. If you are duplicating data from a scheduled backup job, click Run Now.

    The duplicate job will launch immediately following the completion of the scheduled backup job.

  11. If you are duplicating data from an existing backup set, either click Run Now or under Frequency, click Schedule to set the scheduling options you want to use.
