TARGETED DEDUPLICATION USING GROUP FINGERPRINTS AND AUTO-GENERATED BACKUP RECIPES FOR VIRTUAL SYNTHETIC REPLICATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18364985 titled 'TARGETED DEDUPLICATION USING GROUP FINGERPRINTS AND AUTO-GENERATED BACKUP RECIPES FOR VIRTUAL SYNTHETIC REPLICATION

Simplified Explanation

The abstract of this patent application describes a backup system that stores recipes during the creation of backup files using virtual synthetic backups. These recipes consist of a specific sequence of steps used to generate the backup file. The replication logic of the backup system replays the recipe to generate the same backup file on the backup target, combining old backup data with new backup data.

  • The backup system stores recipes during backup file creation using virtual synthetic backups.
  • A recipe is a sequence of steps used to generate a backup file.
  • The replication logic of the backup system replays the recipe to generate the same backup file on the backup target.
  • Old backup data combined with new backup data comprises the recipe.
  • A server-side group fingerprint system auto-generates recipes for server resident files.
  • Files are formulated as a series of L1 fingerprints, which are a set of L0s and GFPs.
  • Some L1 fingerprints are shared with other files.
  • The recipe can convert the file representation from a native fingerprint-based format to a virtual synthetic format.

Potential applications of this technology:

  • Data backup and recovery systems
  • Cloud storage services
  • Disaster recovery solutions

Problems solved by this technology:

  • Efficient and reliable backup file creation
  • Simplified replication of backup files
  • Reduction of storage space required for backups

Benefits of this technology:

  • Faster and more efficient backup and recovery processes
  • Reduced storage costs
  • Improved data protection and disaster recovery capabilities


Original Abstract Submitted

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.
