Abstract
A data storage apparatus that includes a storage device and a processor coupled to the storage device. The processor is configured to receive in a memory, a first logical block entry for a first dump group and a second logical block entry for a second dump group; store in a reverse translation table, the first logical block entry for the first dump group and the second logical block entry for the second dump group; determine a first sequence number associated with the stored first logical block entry and the stored second logical block entry in the reverse translation table, wherein the first sequence number is a snapshot marker that determines a timestamp associated with the first logical block and the second logical block; and persist the first logical block entry for the first dump group in the storage device.
