What is the difference between an incremental and a differential backup?

What is the difference between an incremental and a differential backup?

A differential backup backs up only the files that changed since the last full back. For example, suppose you do a full backup on Sunday. Incremental backups also back up only the changed data, but they only back up the data that has changed since the last backup — be it a full or incremental backup.

What is the main advantage of an incremental backup over a differential backup?

The main benefit of incremental backups is that less is copied every day than if you carried out differential backups. That means you get a shorter backup window on days between full backups, and less storage space is needed for them.
