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
report back on any progress.

As said, I don't mind developing the software.
It's not about snapshots but here is an other incremental
backup recipe for optical mediums like DVDs, BlueRays:
Base Backup:
1) Create encrypted loopback devices of DVD or BlueRay sizes.
2) Create a compressed multi device Btrfs spanning these
loopback devices. (To save space, you may use sin

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?

Daily snapshots work welk with kernel 3.14 and above (I had problems with 3.13
and previous). I have snapshots every 15 mins on some subvols.
Very large numbers of snapshots can cause performance problems. I suggest
keeping below 1000 snapshots at this time.
