3. Backing up over the internet - This is one of those things that sounds great, but only until you actually have a problem. Backing up over the internet is slow and the only real purpose it serves is to maintain an off-site backup. So what happens when you don't have a speedy internet connection (or for that matter, one at all)? That's precisely when you'll have someone that has accidentally deleted a document that they absolutely must have recovered right away! Worse is that it was their mistake, but if for any reason you can't get to the backup, it'll look like yours. After all, this is what you get paid for, right? You can backup data over the internet simply for redundancy, but remember to physically take off-site backups off-site, and always keep on-site backups as well. If you do, you won't have to count on your internet backup to always be available or reliable.
