SERVER-SIDE INLINE GENERATION OF VIRTUAL SYNTHETIC BACKUPS USING GROUP FINGERPRINTS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18365456 titled 'SERVER-SIDE INLINE GENERATION OF VIRTUAL SYNTHETIC BACKUPS USING GROUP FINGERPRINTS
Simplified Explanation
The abstract describes a method for creating inline deduplicated backups of protected data using group fingerprints. This involves generating group fingerprints on a storage server for a backup client that cannot use group fingerprints. The method divides the protected data into variable size segments and generates individual fingerprints for each segment. These individual fingerprints are then grouped together to form group fingerprints, which serve as signatures for the respective data segments.
The method also maintains the group fingerprints for files residing on the storage server. It compares the group fingerprints of these files with a new backup file from the backup client to identify duplicated data. During the backup process, the new backup file is converted into a virtual synthetic backup.
Potential applications of this technology:
- Data backup and recovery systems
- Cloud storage services
- File synchronization and replication tools
Problems solved by this technology:
- Reducing storage space required for backups by eliminating duplicate data
- Improving backup efficiency by using group fingerprints for deduplication
- Enabling backup clients that do not support group fingerprints to benefit from deduplication
Benefits of this technology:
- Reduced storage costs due to deduplication
- Faster backup and recovery processes
- Improved utilization of storage resources
- Enhanced data protection and redundancy
Original Abstract Submitted
Making inline deduplicated backups of protected data using group fingerprints resident in a storage server by generating group fingerprints on a storage server for a backup client that is not capable of using group fingerprints, from individual fingerprints generated for each segment of protected data divided into variable size segments and then grouped together. Each fingerprint comprises a signature for a respective data segment. The method further maintains the group fingerprints for files resident on the storage server, compares, in the storage server, respective group fingerprints for these files with a new backup file to be backed up from the backup client to determine duplicated data between these files, and converts the new backup file to a virtual synthetic backup during a backup time of the new file.
