Investigate backups in more depth

[MoralCode]

Backups are a big thing.

My hope (from that comment) was that the db operator would be able to handle taking the backups and not require user interaction... it'd just happen on a regular schedule. I didn't look into it any farther than to note that there were backup-associated config options.
