Abstract
A method, device, and system are provided for rollback of a master volume in a data storage system. More specifically, when a rollback is requested, snapshots that are involved in the rollback can be deleted during the rollback. This is accomplished by deleting the snapshot partition but not the actual snapshot data. Rather, the snapshot data is retained until the rollback is complete incase some of the snapshot data needs to be written to the master volume as part of the rollback.
