It's easy to say "Encrypt everything," but how do you go about it? For folks looking for an "easy" cross-platform solution to encrypt your sensitive bits in the cloud, check out Cryptomator [^1].

Sadly it has no gui (that I know of) but something like runtestic can help with automated incremental and encrypted backups, where you only want to keep the last n versions (and for example a weekly snapshot)
If you use Gnome, I would encourage you to use it and give feedback here [1]
