Ordering of backup from snapshot jobs
With the NetBackup 9.1 release, all SLP initiated backup from snapshot jobs for Policy, Client, or Backup selection are scheduled in a sequential manner. One scheduled backup from snapshot job must complete before the subsequent job can start. This behavior applies to the NAS-Data-Protection policy also. For example: If there are two scheduled snapshot jobs T1 and T2, and T1 is scheduled before T2. The ordering ensures that the backup from snapshot job for T1 must complete before the backup from snapshot job for T2 is started.
For NAS-Data-Protection policy, if checkpoint restart is enabled and the backup from snapshot job is in suspended or incomplete state, then that job must be resumed first, so that the next backup from snapshot job can run.
