Home > Storage > PowerMax and VMAX > Data Protection > Dell EMC PowerMax and VMAX All Flash: Snapshot Policies > Linking targets and restoring from a snapshot
Link and restore operations are performed in the same way on policy snapshots and manual snapshots. The operations are performed through standard SnapVX interfaces, not through the policies.
When a snapshot with targets linked or in a restored state passes the retention rule of the policy, it is marked as EXPIRED but will not be recycled by the policy. The policy will continue to take snapshots at the scheduled intervals in addition to retaining the linked or restored snapshot. The snapshot is automatically terminated when the target is unlinked or the restore session is terminated.
