plan to access data while Mac in for repair?

So I'm switching over to a Mac and I'm thinking about data backup and recovery. I've got a new MacBook Pro and I'll be connecting a 1Tb external drive for Time Machine. I will also use either Carbon Copy Cloner or SuperDuper to do a clone backup once a week to a separate external drive that I will leave locked up at work (offsite). But...

If my laptop were to die and I have to get Apple to repair it, I understand that I could be without my computer for possibly weeks. How can I get to my data if I don't have another Mac at my house? Are the clone backups of CCC or SuperDuper accessible through Windows, at least to pull out individual files?

In my Windows world, I always have a couple of computers laying around and if I lost a computer (or drive) it was no big deal to just access a backup image I created with Acronis from another computer and pull out files I needed to work on.

 

My offsite backup is the external hard drive that will have the clone (CCC or SuperDuper) that will stay in my desk at work. My question is, if there's a problem with my Mac, will I be able to access any of the data in the backup image from one of the many Windows machines at my disposal.
