Abstract
Systems and methods for backing up data. A backup operation can identify blocks that have changed since a most recent backup operation. The blocks that have changed since the most recent backup operation are compared with the blocks that are being used. Only the blocks that are both used and have changed are backed up. This can reduce the size of the backup be excluding blocks that may have changed but are no longer used.
