You can download some of your Google data using Google Takeout. It’s far from complete, but if you’re still using Google services, it doesn’t hurt to download a backup once in a while.
The problem is that if your account is disabled, it's unlikely you'll be able to acces Gmail, IMAP or otherwise. I think Takeout has an exception so that it works even when your account does not.
It supports Gmail, Google Contacts, Google Calendar, Google Drive (formerly Docs), and Google Reader. By default, the app backs up your accounts every hour and maintains old point-in-time snapshots of your accounts for 90 days. All the data is available in standard file formats.
What a terrible article...
If the data sets do not match then there is no redundancy.
The Unix command line has a wonderful tool called "diff," which compares files line by line.
Or, there's Git, which is even better.
What I'm getting at is that we are the first line of defense when it comes to our data.
I'm sure you've heard the colloquialism, "don't keep all your eggs in one basket?"
If there isn't then what you're doing is called "taunting".
