why with Netapp SnapVault snapshot copy can I choose which client/subclient replicate to SnapVault destination and instead with Netapp SnapMirror snapshot copy I can't ?
for example I have 10 VMware datastores on 10 Netapp volumes:
5 "standard" datastores
4 "mission critical" datastores
1 "test" datastore
for "standard" datastores I want 7 days snapshots on production storage and 30 days snapshots on SnapVault.
for "mission critical" datastores I want 7 days snapshots on production storage, 30 days snapshots on SnapVault and a SnapMirror replica for disaster recovery.
for "test" datastore I want only 7 days snapshots on production storage (no Vault no Mirror)
I can use the same storage policy for "standard" and "test" datastores because in the SnapVault snapshot copy I can chose to Vault only the "standard" datastore subclients (in the Associations tab) but I must use a different storage policy for SanpMirror because in the SnapMirror snapshot copy I can't chose the which subclient to Mirror (Associations tab is greyed)
