Who are we?
We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
We are one. We are legion. And we're trying really hard not to forget.

fsarchiver is very nice. Not fast on pulling out files, but, I mean, it's infinitely faster than tar.
Only quit using it so much because zfs-send is the real big hammer.
Best part is it can regenerate partitions, or whatever, or you can restore a larger partition to a smaller one, all the cool permutations assuming the files actually fit. Can re-write users and permissions if you like, all the bells.

Oh, also you can always copy it over to an iso image and mount it, or a qcow or raw image of some kind for loop mount.
