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 sequentially. One scheduled backup from snapshot job must be 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 be complete before the backup from snapshot job for T2 is started.
For the NAS-Data-Protection policy, if checkpoint restart is enabled and the backup from snapshot job is in a suspended or an incomplete state, then that job must be resumed first, so that the next backup from snapshot job can run.
With the NetBackup 10.4 release, you can configure a multi-stream policy containing a backup host pool with multiple hosts. This way, you can distribute the stream among all available backup hosts equally and on the best available resource hosts.
