Abstract
A method for restoring a data volume using incremental snapshots of the data volume includes creating a first series of incremental snapshots according to a first predefined interval. The method further includes creating a second series of incremental snapshots according to a second predefined interval that is an integer multiple of the first predefined interval. The method also includes receiving a request to restore the data volume to a point-in-time. The method further includes restoring the data volume to the point-in-time using none or some of the snapshots in the first series that were created at or prior to the point-in-time, and all of the snapshots in the second series that were created at or prior to the point-in-time.
