I was under the impression that a sync command just doesn't do the trick. It 
kicks in the cleaner but returns to early. But I din't try that again 
lately.

But I'm actually currently using "btrfs fs sync" to do it because a normal 
"sync" command would affect all my filesystems and I'd like to keep it 
isolated.

I'll post a link to my backup script for reference in another post in this 
thread.
