Disclosed herein are techniques for generating fractional checkpoints on a distributed file system by snapshotting subcomponents referred to as 'file sets.' The techniques include capturing a present time; calculating from configured parameters a future wakeup time for a subsequent set of checkpoints from the present time; walking a database of meta file set objects to locate at least one meta file set object; calculating a retention period for a snapshot that is being created; and generating a global data-less snapshot for the meta file set object and remote data file set objects associated with the meta file set object, and then repeating the process for subsequent file set objects in the database.
