SnapVault update schedules for volume SnapMirror destination backups

When backing up a volume SnapMirror destination using SnapVault in Data
ONTAP 8.0.2, the snapvault.snapshot_for_dr_backup option allows you to
choose the SnapVault behavior for updating the destination system.
You can set the following values for the snapvault.snapshot_for_dr_backup
option:
v named_snapshot_only: Schedules the SnapVault updates from the most
recent Snapshot copy with the scheduled base name for scheduled backup.
v named_snapshot_preferred: Schedules the SnapVault updates from the most
recent Snapshot copy created by volume SnapMirror if the scheduled
Snapshot copy is not available.
v vsm_base_only: Schedules the SnapVault updates from the most recent
Snapshot copy created by volume SnapMirror. This is the default value.
