Abstract
A data protection technique involves, based on a first set of policies on a first storage array, generating a second set of policies on a second storage array to track the first set. The first array maintains a first storage object, and the second array maintains a second storage object as a replica of the first storage object. The technique further includes detecting assignment of the first set of policies to the first storage object and, in response to such detection, assigning the second set of policies to the second storage object. Application of a set of storage policies to a storage object may be delayed if the storage object is a replication destination. A policy group may identify multiple data protection rules or policies, which may include a snapshot rule and/or replication rule, and a user may be prevented from directly making a rule modification to a policy group. An orphan policy group cleanup operation may be performed to delete orphan policy groups.
