Abstract
Targetless snapshot schedules are defined by policy objects that include a snap creation interval, maximum snap count, and schedule ID. Multiple schedule IDs can be associated with a single storage object to implement different concurrent targetless snapshot schedules with a single storage object. Multiple storage objects may use the same targetless snapshot schedule independently. Because the targetless snapshot schedules are implemented independently, discard of old snapshots to maintain a snap count for a first storage object does not cause discard of snapshots for a second storage object. Further, discard of old snapshots to maintain a snap count for a first schedule does not cause discard of snapshots for a second schedule applied to the same storage object.
