ABSTRACT:
An embodiment relates generally to a method of restoring data in storage systems. The method includes providing for a current snapshot of a primary storage system at a secondary storage system and mounting an empty volume in the primary storage system. The method also includes receiving a request for a selected block of data in the primary storage system and retrieving a restore block from the secondary storage system, where the restore block encompasses the selected block of data. The method further includes writing the restore block to the empty volume in the primary storage system as an incremental restore process.
