OneFS Release 9.3.0.0 introduced support for writable snapshots. Although SnapshotIQ snapshots may be specified for SyncIQ replication, writable snapshots are not supported for SyncIQ replication. If a writable snapshot is specified as the source or target, the data replication fails. Further, creating a writable snapshot based on a SyncIQ generated snapshot is not supported. For more information about writable snapshots, see the Dell PowerScale OneFS Writable Snapshots whitepaper.
