What is the difference between incremental and differential backup?

188 viewsOtherTechnology

Hello folks, I have run out of brains today and can’t seem to grasp the difference between incremental and differential backups, try as I might. I read TechTarget and AWS definitions, but bits like this:

>A differential backup strategy only copies data changes since the last full backup. On the other hand, an incremental data backup strategy copies data changes since the last backup.

…sound exactly the same to me; or rather, have exactly the same outcome in my mind. Anyone care to explain it like I’m five? Feel free to use anything as analogy.

Incremental only backs up the changes the first time they are detected. Differential backs up the changes every time it’s run, meaning restore is faster and you don’t need the previous differential backup, like you do with an incremental backup
