Abstract: Techniques for data management are described. A monotonically increasing time source that indicates an elapsed time since a reference event may be activated. Multiple snapshots of a computing object may be generated in accordance with a schedule for backing up the computing object, where the schedule may include a retention duration for retaining snapshots. Based on generating the snapshots, timestamps for the snapshots may be stored, where the timestamps may indicate respective values of the monotonically increasing time source. As part of an expiration job, a reference value of the monotonically increasing time source may be identified based on the retention duration and a current value indicated by the monotonically increasing time source. Also, a snapshot of the snapshots may be expired based on a timestamp of the snapshot corresponding to a value of the monotonically increasing time source that is less than the reference value.

Abstract: A data management system (DMS) may capture snapshots of a computing object in accordance with a service level agreement (SLA). The DMS may store the captured snapshots in a cluster of storage nodes at the DMS and/or transmit the snapshots to one or more external archive locations. Which archive location to store given snapshots of the computing object may be based on archival policies defined in the SLA. Some snapshots may be stored locally at the DMS, some snapshots may be stored in one archive location of a set of multiple candidate archive locations, and some snapshots may be stored in more than one archive location of the set of multiple candidate archive locations. A retention duration for each snapshot may be independent of the archive location for the snapshot. For recovery purposes, a user may specify from which archive location the user selects to retrieve a snapshot.

Abstract: A technique includes running a sand control completion system into a well, where the system includes at least one sensor, a gravel packing service tool and a sand control section. The sand control completion system is used to perform a gravel packing-related operation in the well in which a slurry is communicated downhole through the service tool to deposit gravel near the completion section. The technique includes regulating the gravel packing-related operation based at least in part on data acquired by said at least one sensor and communicated to an Earth surface of the well while the operation is being performed.
