All files (and data) I have on my Linux machine is either a copy from a cloud (i.e git, photos, contacts) or synced to Dropbox Family (and some are even encrypted). In case of a ransomware, I would just revert to a previous version of that file. I dont have any physical backups but for some stuff I have multiple manual backups on cloud. As for protection I try to follow general security guidelines: I mind all the packages I install (including dependencies like npm), I have ABP and nextdns on my browsers, I use Arch and update it every morning, and I disable any sw or hw feature (bluetooth, sdcards, usb boot) that I do not use, to give some examples. I have a feeling reducing attack surface should be enough for me.
