SnapMirror Commands

The snapmirror commands enable you to create and manage data protection mirrors, extended data protection relationships, and load-sharing mirrors.

These commands are available to the cluster and Vserver administrators.

When a SnapMirror relationship is created with the type of the relationship specified as data protection (DP), an extended data protection (XDP) relationship will be created. This relationship will provide the same functional behavior as the DP type in terms of Snapshot copy selection and retention. This is achieved by using a policy which has the rule to replicate all Snapshot copies. There is an exception to this relationship creation behavior of overriding of the type DP. If a relationship of type DP in the opposite direction already exists, the new relationship will also be of type DP. The type DP will eventually be deprecated and applications should not use this type when creating new relationships. When the type is specified as DP or when no type is specified, if a policy of type async-mirror is specified that does not have the rule to replicate all Snapshot copies, the snapmirror create command will fail.
