I use Backblaze to backup my gaming PC. While .git and Dropbox does not affect me it’s worrisome that OneDrive is not backed up seeing as Windows 11 somehow automatically/dark pattern stores local files in OneDrive.

You have to give Apple credit, they nailed Time Machine. I have fully restored from Time Machine backups when buying new Macs more times than I can count. It works and everything comes back to an identical state of the snapshot. Yet, Microsoft can’t seem to figure this out.
