Is the Snap! server backed up?

I'm not sure what category to put this in.

Probably not.

We back up individual projects -- see "Recover." We don't explicitly back up the entire server; since it's kept on a virtual disk provided by our cloud service, I would guess they maintain some redundancy but I dunno the details.

Would that be the way off-topic one I deleted?

Yeah, off topic. You're just bragging, not answering the question.
