Although a SyncIQ policy configures the target directory as read-only, SnapshotIQ snapshots are permitted. As a best practice, consider configuring target cluster SnapshotIQ snapshots at a differing schedule than the source cluster, providing an additional layer of data protection and a point-in-time dataset. Target snapshots could also be used as a longer-term retention option if the cost of storage space is less than the cost of storage space of the source cluster. In this arrangement, the source cluster snapshots are retained short term, target cluster SyncIQ snapshots are medium term, and the long-term archive snapshots are SnapshotIQ snapshots on the target cluster.
