What Microsoft calls OneDrive's "backup" feature seems to have a misleading name to me. It's more like cloud storage than a proper file backup. Sure, fine. But I'm trying to be smart about how I use it, aware of the risks and best practices.

Unfortunately, it's hard to actually GET informed. Most tutorials are made or sponsored by Microsoft, and in this age I don't really trust a corporation to give me an honest assessment of their own product's faults.

So what can I ACTUALLY expect with OneDrive "backup"? I'd like to have all my files available to me across devices, but I also want to feel secure that those files are safe online- the Personal Vault seems dubious, though.
