You must configure a media group with the
Parallel backups are only possible for data backups (complete and incremental).
Requirements
The NetWorker command SAVE or RECOVER is started for each pipe. NetWorker requires the exact name of each backup pipe for a restore. The media group must therefore be configured in exactly the same way during the restore as during the backup. This includes the order of the media in the media group.
The number of tape drives should be the same as the number of pipes used for the backup.
Set the NetWorker parameter Target Sessions for each tape drive to 1.
Procedure
If you want to perform a parallel backup or restore, follow the procedure described in the following documentation:
If a deadlock occurs during a parallel restore, you must import the backup sequentially (that is, from the individual media in the media group) using the Database Manager. Test this procedure.
