When Windows users suddenly discover that their files have vanished from their desktops after interacting with OneDrive, the issue often stems from how Microsoft’s cloud service integrates with the operating system. The automatic, near-invisible shift to cloud-based storage has triggered strong reactions from users who find the feature unintuitive and, in some cases, destructive to their local files.


OneDrive is for syncing files across devices. It’s not a backup.
Edit:
Since there seems to be a lot of hate on my comment, allow me to explain.
Backup software has a schedule, it has monitoring, it has alerting (email, SMS, ticket submission, etc), and checksumming. OneDrive frequently just shits the bed for whatever reason, often goes unnoticed in the corner, and users frequently miss it and nobody, not even IT, know. Not to mention it’s riddled with bugs.
Yes, you are copying files from point A to point B but it is not the same. If you rely on onedrive as a “backup” you’re going to be disappointed at some point when you lose your files :)
If you delete a file over here, then it disappears from over there. That’s not a backup. On a real backup, if you delete files or lose them or whatever, you have days/weeks/months to go back on versions to restore.
So like syncthing but you have to pay for it and requires a server. Seems useless…
If you want to sync while not all devices are online, just spend 50$ or something and get a RPI and put syncthing on it.
