Re: Backup failing with "failed to clone extents" error

I'm not sure how this would happen. These subvolumes were all created
with snapper (snap-sync just calls snapper). They were not received
from another filesystem, and I don't think they've ever been RW
(unless snapper for some reason does that?).
Received_uuid is actually the same on *all* my snapshots, and it's the
same as the original "@root" subvolume as well. Is each one supposed
to have a unique received_uuid? Is this somehow because my "@root"
subvolume was originally created by receiving from another btrfs?
$ for x in /.snapshots/*/snapshot; do btrfs subvolume show $x|grep
