Abstract
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.
