Abstract: A set of snapshots are stored for a first object. The first object uses a first logical unit number (LUN) to store data. The snapshots correspond to points-in-time that the first object may be rolled back to. A request is received for a directed rollback of the first object to a second object. The request specifies a particular snapshot of the set of snapshots. The second object uses a second LUN, different from the first LUN to store data. After receipt of the request, a discovery map of the second object is dynamically created. The discovery map specifies a storage stack associated with the second object that maps the second object to a physical storage device accessed through the second LUN. The directed rollback to a point-in-time corresponding to the particular snapshot is performed by obtaining, from the discovery map, the storage stack associated with the second object.

Abstract: In one example, a method for protecting data includes receiving input specifying a data backup process, consulting a resource map to identify backup resources that are available, and then checking a rules engine to identify a backup rule that matches the specified data backup process and that can be executed to perform a backup using the available backup resource. When a backup rule is identified that matches the specified data backup process and that can be executed to perform a backup using the available backup resources, the specified backup process is automatically performed using the identified backup rule.
