Efficient Distributed Backup with Delta Compression - Burns, Long (1997) (6 citations) (Correct)
....up only those files that have been modified since the end of the last epoch, the period between two backups. While incremental backup only detects changes at the granularity of a file, delta backup refines this concept, transmitting only the altered bytes in the files to be incrementally backed up [12]. Consequently, if only a few bytes are modified in a large file, the backup system saves the expense of transmitting the large file in favor of transmitting only the changed bytes. Recent advances in differencing algorithms [1, 4] allow nearly optimally compressed encodings of binary inputs in ....
