Abstract
Techniques are provided for storage system backup and de-duplication. In an example, a file system stores a plurality of files. These files can be grouped into smaller sets through a series of iterations, where a set of files is similar to each other. Then, files of a set of files can be directly compared for duplicate information relative to each other, one copy of this duplicate information can be stored, and other copies can be discarded.
