BTRFS and file-system compression has been an absolute boon as a penniless student with finite space on their 512 GB SSD. Even a backup snapshot scheme of five system changes, four daily, three hourly, one weekly and one monthly with spares saved to other location should do the trick.
As BTRFS is a copy-on-write, failing catastrophic corruption which is occasionally known the happen with the filesystem. You should still be able to keep a backup of the previous states of your system and the files on them for a reasonable length of time. I used to do the very same on Arch Linux before eventually moving to NixOS.

@Saorsa Funnily enough while I don't think this solves any of the problems (setting up a snapshotting strategy on btrfs is a pain in my experience and I wouldn't expect casual users to figure that out, let alone the catastrophic corrruption which is still known to happen on btrfs), my backup strategy is actually somewhat related as I zfs send/receive a large zfs pool onto some hard drives that I keep in various places around the country and rotate around when I visit them. But again I don't think this solves any of the fundamental issues, because I had to write a damn shell script for doing this!
