Abstract
In one approach, data blocks or files that have a history of change are tagged for automatic transfer to backup on the assumption that they have changed since the last backup. Other data blocks and files are first tested for change, for example by comparing digital fingerprints of the current data versus the previously backed up data, before transferring to backup.
