Abstract
Performing changed sector backups on a volume to improve the throughput of incremental backups for block-based backups by overwriting only modified data on each changed block. Latency reduction is achieved by not overwriting the changed block as a whole. The previous backup is cloned and the batch file in the clone is updated by considering the incremental block extents. The incremental data write is performed only on the changed data of each incremental block from a couple of offset values from the previous backup's clone. Dynamic disk rather than differencing disk containers are used for snapshots. Use of a previous backup clone eliminates the need for temporary virtual disk containers, and fixed-size segmentation at the target reduces fragmentation and eliminates the need to enforce variable-sized segmentation.
