Claim 0:
1. A method at a data management service (DMS) cluster, comprising:
activating a monotonically increasing time source that indicates an elapsed time since a reference event;
generating a plurality of snapshots of a computing object in accordance with a schedule for backing up the computing object, the schedule comprising a retention duration for retaining snapshots of the plurality of snapshots;
storing a plurality of timestamps for the plurality of snapshots, the plurality of timestamps indicating respective values of the monotonically increasing time source associated with generating respective snapshots of the plurality of snapshots;
identifying, as part of an expiration job for expiring one or more of the plurality of snapshots, a reference value of the monotonically increasing time source, the reference value of the monotonically increasing time source based at least in part on the retention duration and a current value indicated by the monotonically increasing time source; and
expiring a snapshot of the plurality of snapshots based at least in part on a timestamp for the snapshot corresponding to a value of the monotonically increasing time source that is less than the reference value of the monotonically increasing time source.
