Thanks everyone for the responses. I'll start setting up my backup
strategy in 2 or 3 weeks. I'll give the diff and unionFS tips a go, and

Thanks for the replies, I think that's most of the questions answered.
I'll not bother backing up any VMs, as they won't contain anything worth
backing up. Can anybody answer the last couple of remaining questions?

2) Create a compressed multi device Btrfs spanning these
loopback devices. (To save space, you may use
