Abstract
Techniques for reducing overheads of primary storage transferring during a backup by transferring in an out-of-order manner are described herein. According to one embodiment, in response to a request at a primary storage for a backup of a plurality of data blocks, a transfer order of dirty data blocks is determined based on an access assessment of the dirty data blocks, wherein the dirty data blocks are data blocks of the plurality of data blocks that have been changed from a previous backup, and wherein the transfer order is different from a sequential logical order of the dirty data blocks provided by the primary storage. Then the dirty data blocks are transferred to a secondary storage in the determined order.
