Abstract
A backup system stores recipes during backup file creation when virtual synthetic backups are used, where a recipe comprises a specific sequence of steps used to generate the backup file. Replication logic of the backup system replays the recipe to generate the same backup file on the backup target so that an old backup combined with new backup data comprises the recipe. Embodiments of a server-side group fingerprint system include a process to auto-generate recipes for server resident files by formulating a file as a series of L1 fingerprints which are in turn a set of L0s and GFPs where some of the L1s are shared with other files. The recipe can be used to convert the representation of the file from a native fingerprint based representation into a virtual synthetic format.
