Backing up the blog and website

After enduring the latest outage with Vizaweb -- 36 hours -- I realize how essential it is to have a weekly backup of everything on my site. There's no automated way to do it that I know about, although there must be some way to do that. I'm going to have to back up things myself every week at least because the pain I would have to go through without a backup would be too much. It has made me realize how important it is to have a reliable host. Vizaweb has generally been fine but they often don't respond to email and don't communicate well. That's not a good thing when it's not working.
