Abstract
A data processing device receives a manifest from a previous backup operation and determines what files have changed by comparing the files to be backed up to the manifest. The data processing device then transforms and encrypts the new and modified files, updates the manifest, signs the manifest and sends the encrypted files along with the signed manifest to a host data processing system for backup.
