Abstract
A system and method for backing up files to a single-instance storage system are disclosed. The files may be split into segments, and the file data may be stored in the single-instance storage system as individual segments. The single-instance storage system uses the concept of a file region which covers multiple segments of the file. If a region of a file is unchanged from one backup to the next, the system may use a region object to refer to the unchanged region. This avoids the need to update the reference information for each of the segments within the region, thus increasing the efficiency of backing up the new version of the file.
