Abstract
Techniques for transferring modified data with efficiency are described herein. According to one embodiment, the method starts with analyzing host write data to determine a host write pattern of a host writing to sectors at a primary storage, and then a data block size and a backup interval are determined based on at least one of the host write pattern, wherein a data block includes a number of sectors that is determined based on the host write pattern, and known characteristics of transferring dirty data blocks of the primary storage, wherein a dirty data block includes at least one sector that has been changed from a previous backup. Then dirty data blocks are transferred from the primary storage to a secondary storage as part of a backup.
