But Google Apps is a pain in the butt to backup, since we don't have direct file access to things. The best strategy I can see, if you want to stick with it, is to email yourself every file, every edit. That's pretty insanely tedious.
Automatic daily Google Apps backups -- all of it, even Google Sites -- for just $3 per user per month. Unlimited storage. One-click restore for Google Docs and Gmail messages. And we're soon rolling out full-domain search, so you can query all your Gmail, Docs and Calendar accounts simultaneously.
We also backup your Twitter Feed, your Facebook Pages and your Flickr or Picasa photo albums, should the need arise.
Also, for the record, we have a 1-800 number that we actually answer, so in the event you have trouble with our service, we'll pick up the phone and talk you through the fix. We can't repair your Apps account, but we can darn well make sure you get to the data that's in it. We wouldn't charge you, otherwise.
Do you have any integration (or plans for integration) with Dropbox? I'd love to sign up to a service that simply dumps a copy of all my backed up files to a Dropbox folder somewhere, once a week.
Our Pro 500 plan is $19.99 per month and includes 10 Google Apps users and unlimited storage. That actually breaks down to less than $2 per user per month. Beyond that first ten, additional users are $3 per user per month. I usually just quote the $3 figure for simplicity's sake, especially since most admins using a paid Google Apps domain (Google Apps Premium) have more than 10 users anyway.

But he's an operations guy like me, and he probably wears both a belt and suspenders just in case the belt breaks. So in response to the complaint that emailing yourself files to insure you have copies is a pain, I suggested he script the moral equivalent using Google's provided APIs to the docs service.
