> There are a couple of good file system options, but I chose btrfs for a couple of reasons. Subvolumes work in practice, like more convenient partitions, snapshots are incredibly useful for backups (more on that later) and compression can save quite a bit of space on the not-so-big included SSD, which also reduces wear.

I am also running btrfs (as the default disk partitioning on Fedora 40). I used to do regular snapshots with snapper on my laptop but at some point ~20% of my SSD were reserved for metadata. From that only 10% was used (so 2% overall) without any apparent possibility to reduce the reserved space.

These days, I do snapshots only on my homeserver (which is running syncthing) but not on my laptop.
