Abstract
A system and method for efficiently providing snapshots in storage systems. The method includes creating a plurality of snaplines for a storage system, each snapline having metadata including a timestamp and a status marker for each of a plurality of offset ranges, wherein each offset range corresponds to data stored in the storage system, the storage system including a plurality of compute nodes, wherein the timestamp of each snapline is a value of a global counter at a time of creation of the snapline, wherein the global counter is uniform among the plurality of compute nodes; and creating a snapshot based on the plurality of snaplines and a time value, wherein the snapshot indicates a snapline of the plurality of snaplines that is not to be deleted, wherein the timestamp of the snapline that is not to be deleted corresponds to the time value.
