Incremental Backup
Incremental backup consists of creating one full backup followed by a chain of incremental copies that contain information about how the data has changed since the last copy.
A great advantage of this type of backup is increased speed of backup performance. You will notice the difference especially with large files that don’t change much or often. Moreover, it’s more efficient when it comes to storage—incremental backups require much less storage space. Also, they take less time.
However, there is one disadvantage of incremental backup: it makes restoration more difficult compared to restoring only the full copy. This is because both the last incremental backup and the last full backup need to be restored.
