Browsable Daily Backups
Producing backups is a feature which is offered by nearly all Internet hosting providers nowadays. That's a rather useful function as it's a guarantee that you will not lose valuable information in the event that something happens with your sites and there are plenty of possible reasons for that - someone getting access to your account, deleting content by mistake, carrying out an unsuccessful update of a script-driven program, and so forth. Provided that you have a backup, the damage in any of these cases is easy to fix, but you'll need to respond fast as most firms keep only one backup a day and each new one removes the previous one, so a delay of 2 days means losing everything.
