Incremental vs Differential Backup.


What is the difference between Ahsay's In-File Delta block level incremental and differential backups? Which one is better? Let us take a look. Incremental backup backups the delta comparing to the previous backup job, while differential backup backups the delta comparing to the initial backup file (seed). As a result, incremental backup is faster than differential backup. On the contrary, during file restoration, restoring file backed up through differential method is faster. Because it only requires 2 deltas to complete the restoring job, that is combining the seed file to the delta file which is needed to be restored. On the other hand, ALL deltas are required to restore a file backed up through incremental method. In conclusion, both backup methods have their advantage and disadvantage. An optimal data protection strategy should includes both backup methods, so that it can achieve maximum backup performance and flexibility during backup and restore.
