Nice question "Brandie Tarvin". Incremental is in Windows backup types & Differential is in SQL Backup types so its a googly ball :-)

Thanks

Interesting. I've never heard of a partial backup, and am struggling to figure out how it would be useful...will have to do some research!

Good question. I answered it wrong even though I knew the correct answer. What fooled me was the incremental backup. I know there is nothing called an incremental backup, but I have also seen that transaction log backups sometimes are referred to as a kind of incremental backup, so I though "is this a trick question?". Lesson learned: always trust my initial instinct.

Partial Backup caught me out on this one, had the others. So there's a "learning opportunity" for me. ;-)

Argh! (Is it talk like a pirate day?)
Too much time as a windows admin, incremental backup. Partial backup is a new one on me. Good question, thanks.

I'm glad the question has helped so many people. I did not realize how few people knew about File and Partial backups.

Nice question as far as it goes.

But it would have been nice to go a bit further and have a few more backup types, a list like

Database backup
Differential database backup
Partial backup
Differential partial backup
File backup
Differential file backup
Log backup
(plus of course incremental backup and maybe more spurious ones)

so that it's clear that the Database/Partial/File distinction is orthogonal to the Full/Differential distinction, giving 6 possibilities plus the log backup to make 7.

And then does WITH Copy Only introduce some more types and if so how many - but maybe that could be a separate QotD.
