The replica copy is an additional copy of the snapshot primary copy. The snapshot primary copy contains the metadata of the snapshots of the local array. The replica copy contains the metadata of the snapshots of the remote array.
Before You Begin
Use a storage policy with a snapshot primary copy. If you haven't done so yet, create a storage policy and a snapshot primary copy on that storage policy.
For inline replication, you can create only one replica copy. If the storage policy already has a replica copy, then the Create New Snapshot Copy command appears dimmed.
