Snapshot method: Auto
Error scenario 1: Policy validation fails, after a primary server upgrade, if you create a policy with VSO FIM for older clients and select Snapshot Method as Auto in the NetBackup 10.0 UI.
Error scenario 2: Snapshot jobs fail, if you configure DNAS policy with backup host pool containing older version backup hosts and select Snapshot Method as Auto in the NetBackup 10.0 UI.
The Snapshot Method, Auto is supported only in NetBackup 10.0 onwards. If your environment contains older version backup hosts, select another snapshot method.
