Abstract

A method is used in managing deletion of replicas of files. A request is received to delete a replica of a file of a file system. The replica of the file represents a state of the file at a particular prior point in time. The replica is associated with a group including a set of replicas of the file system identified for deletion. Each replica is deleted in the group concurrently by using a delete marker. The delete marker is used for tracking deletion of each replica in the group.
