Yeah, but rolling upgrades are a PITA anyway so what else's new. Also,
linux-to-linux you're pretty much on the same zfs version on all boxen,
and so far I have not seen any problems between e.g. centos 7/zfs 0.8.1
and centos 6/zfs 0.8.3.
Also, how do you backup the backup box itself?
I don't. ;)
Yes, it you want all your change history in a tape archive in a vault
somewhere far away, that would be a problem because snapshots are not
visible to your tape backup software. But then you may want to consider
putting your stuff on GitHub: it's better at tracking version history
than incremental tapes, easier to restore, and might actually cost less
than the tapes and the vault and the monkey to cart the tapes there and
back.
