Well, this time there were still 2 ENOSPC errors.  But I can show the df output
after such an ENOSPC error, to illustrate what I meant with the sudden surge
in total usage:

# btrfs filesystem df /run/media/marcec/MARCEC_BACKUP 
Data, single: total=236.00GiB, used=229.04GiB
System, DUP: total=32.00MiB, used=36.00KiB
Metadata, DUP: total=4.00GiB, used=3.20GiB
unknown, single: total=512.00MiB, used=0.00

And then after running a balance and (almost) immediately cancelling:

# btrfs filesystem df /run/media/marcec/MARCEC_BACKUP 
Data, single: total=230.00GiB, used=229.04GiB
System, DUP: total=32.00MiB, used=36.00KiB
Metadata, DUP: total=4.00GiB, used=3.20GiB
unknown, single: total=512.00MiB, used=0.00
