If you're not running backups on the regular I suggest that. Check with your host as some offer automatic backups solutions (some are hourly/daily/other) and there may or may not be a charge for it. You can always run backups yourself at least once a week.
Why the backups? Well one disgruntled moderator going clickity-click-click deleting threads and posts before they let the door hit them on the way out sure will have you running backups more often, you have been forewarned
