I’ve been reading a lot about BTRFS these days, to get a decent setup with subvolumes. The most important thing I learned is that the subvolumes have to be created before installation, something what Antergos didn’t automatically do for me.

What I would like to know if it’s a good idea to take a back-up of my current system, reformat the drives with the wanted subvolumes so I can take snapshots later on (the whole point I chose for BTRFS in the first place) and move the contents back.

Anyone have any experience with this or can give a piece of advice?
