I'm trying out the btrfs send|receive command as shown on the
incremental backup wiki page, but the command is failing. I've tried it
with sudo as it had not permitted errors, but still no luck. The output
is:
s@s-Air:~$ btrfs send /home/BACKUP | btrfs receive /media/s/99b1c51d-b3bb-4179-a621-9d5a27acc385/Air
