As usual with Btrfs, there are corner cases to avoid: 'defrag'

Good hint. So far I did it the other way: balance before defrag. 
I will switch.

and with compression switched off

I have filesystems with compress mount option:

framstag@fex:~: grep /local /etc/fstab
LABEL=local /local btrfs  defaults,compress,user_subvol_rm_allowed 0 2

and a weekly cronjob, which does a defrag and balance.
I cannot disable compression.
Any hint here?

I prefer dump-and-reload.

What do you mean by this?
