When you are using SnapVault in combination with Volume SnapMirror, it is important to understand their relationship with Snapshot. You cannot utilize SnapVault to protect a Volume SnapMirror destination, because SnapVault and SnapMirror both use the same Snapshot copies; they cannot run simultaneously. Schedules must be managed to accommodate the interlock that keeps SnapVault and SnapMirror from stepping on each other.
