How to use SnapVault to protect a volume SnapMirror destination

You can use SnapVault to protect a volume SnapMirror destination. You can perform SnapVault transfers from the volume SnapMirror destination when you want to retain the data for a longer period.

In this deployment scenario, data from various primary systems is replicated to a remote site for disaster recovery. Volume SnapMirror ensures identical data at the source and destination systems. If you want to retain the data for a longer duration (that is, 90 days and more) at the disaster recovery site, you can use SnapVault to back up data from the SnapMirror destination.

When using SnapVault to back up a SnapMirror destination volume or qtree, you need to ensure the following:

To use the SnapVault backup schedule, you need to configure the SnapVault primary schedule at the volume SnapMirror primary system. Therefore, you need the SnapVault license installed on the volume SnapMirror primary system. However, you do not need the SnapVault license on the volume SnapMirror primary system if you want to use the Snapshot copies created by SnapMirror.
