Abstract

A system is described herein. The system includes a backup server for backing up user files. The backup server includes a storage device for storing a base file corresponding to a first backup instance of a file and deltas that represent changes to the file. The backup server also includes a file backup manager that receives the base file and the deltas from a user's computing device; wherein deltas are received on subsequent operations pertaining to the file. A file reconstruction manager is included that generates a tip version of the file from the base file and the deltas, and sends the tip version to the user's computing device. Additionally, the backup server includes a cache memory that stores the tip version so that it is available for subsequent downloads corresponding to additional requests for the file.
