I use ZFS on my main computer, but it sends its backups to a tiny computer with two laptop USB drives plugged in, running Btrfs RAID-0. (The second drive was added when the first one filled up.) I did it that way because it's the second copy of the data, and I'll only need to call on it if my main computer dies. I have a sentry program running on the tiny computer that regularly checks that all the data is present, correct, and readable. The likelihood that it breaks at the same time as my main computer is slim.

I wouldn't trust Btrfs for much more than that.

I specified ZFS for some of work's very large servers (>100 drives). They wanted to do hardware RAID and XFS instead, and I can just image the nightmares that would have involved.

What is kind of neat for your case maybe is that you can run btrfs scrub even on raid0 or a single drive. The scrub command reads the whole filesystem and verifies checksums, so you can be sure that the data is readable and correct.

Disclaimer: I only tried it on a single disk.
