So my hosting provider (Dreamhost) somehow, accidentally deleted my databases. I sure was glad to have a backup (as they did not)! Unfortunately, the most recent backup that I found wasn't as current as I would've liked- so I lost a lot of content. It's just good general practice to take database snapshots as often as possible and archive them somewhere off-site. Hosting providers, sometimes, provide tools to do this. You can also do this manually whenever you like.
