If you think you'd find yourself regularly backing up large amounts of changing files, and you want features that most people would associate with a real backup solution (like maintaining a history of file changes, doing differential backups, etc), then you're far better off going with a cloud solution that was built to be a backup solution (like AWS Backup and Restore), which OneDrive just isn't. It can, but only for very simple backup scenarios. So again, in a nutshell, OneDrive just isn't a good solution for anything but the most trivial of backup problems.

Of course you could forget about all of that and just regularly dump all your files onto OneDrive, but due to bandwidth throttling, doing so regularly for large amounts of data can become a pain in the rear. That is anything but a user friendly backup solution. However, if you're looking to backup a large amount of documents that change often, then turning off OneDrive's syncing requires you to find out on your own which files have changed since your last backup and then manually sync only them. That's more or less just a dump of static data that you'd use only for disaster recovery. If you're mainly looking to backup files that never change (video, audio, etc), then I think OneDrive is a viable backup solution, because you can then turn off syncing without having to worry about keeping local and cloud copies of the same files in sync (because they never change).

It just won't be a good backup solution, because like I said, that's not what OneDrive was built to do. Performance decreases as the total numbers goes up, this limit also depends on your client device performance.Thanks for the reply! So just by turning off syncing it can serve as a backup solution?Yes.
