I understand that usebackuproot requires kernel >= 4.6. I probably won't

installing a custom kernel, but if I still have the array in its current
state when 4.6 becomes available in Debian Stretch, I'll give it a try.
It's the "recovery" mount option in older kernels.
That didn't work, one of the first things I tried. Crashes just like without
it.
-o ro,recovery is quite a bit more tolerant in my experience. While
it's not great to in effect have a read only file system, it's a lot
easier to get data off of if necessary, rather than restoring to
'btrfs restore'.
Read-only mounting works even without recovery. My current plan is to copy
most of the data (I probably skip snapshots even though that defeats part of
the purpose of backups) once I get new disks. I have also run --repair, but
that didn't have any effect.
