There seems to be no backup solution which supports BTRFS in a way that I 
can just restore the complete partition with all subvolumes, snapshots ? 
That's bad. A fs can also get corrupt in certain circumstances.
I'd like to have a solution which offers me the possibility to restore a 
root partition in a reasonable time (some hours maximum), completely. Not 
doing many stuff before/afterwards. It seems that's not possible withBTRFS.

And Btrfs check is still limited in what it can do.
