The auto-delete option must be disabled on the following volumes:

volume snapshot autodelete modify -vserver <vserverName> -volume <Volume Name> -enabled false - trigger volume

If an old snapshot is selected during PIT rollback, all new snapshots created after that snapshot are deleted automatically from the array.

Fan out of replication topology is not supported with synchronous replication.

You can have a maximum of eight fan out relationships from a single source volume.

If you create any new replication relationship between source and destination apart from the ones mentioned in the Policy Name, Policy Type, and Replication Type table, then the new relationship is considered as NetApp_SnapMirror.
