I've tried that many times. It takes the snapshot (or so it seems) always from zero, which takes a while. But it just won't save it anywhere.

Not sure, what you mean by "takes the snapshot from zero".
Do you have different subvolumes defined (and mounted) in your BTRFS filesystem for / and /home (plus maybe some more)?
Creating a ro snapshot of a subvolume should be instant. Only if you want to send/receive it somewhere else, should it take time (depending upon the amount of data to be transferred).
Are you using a third party utility to automate the snapshots?
