rsync + btrfs works incredibly well IMHO. I have three drives in different locations, and periodically rsync my home to each of them, then take btrfs snapshot.

I have three drives in different locations, and periodically rsync my home to each of them, then take btrfs snapshot. rsync lets you exclude things in a finegrained way, similar to .gitignore. So I avoid saving huge binaries that can be recreated. All this takes two lines of code. Rotating snapshots is also quite easy.
