Abstract
In one approach, a set of data blocks or files is tracked for changes between snapshots. This may be done by a file system filter running in kernel mode. The data blocks or files that are tagged as unchanged are not transferred to backup because there is no need to update since the last backup. Other data blocks and files may be first tested for change, for example by comparing digital fingerprints of the current data versus the previously backed up data, before transferring to backup.
