Hi Gary,
Short answer: no, you don’t need all three.
Here’s what each one does:
- OneDrive comes built into Windows 11. It backs up your Desktop, Documents, and Pictures folders (if you turn that on) and syncs them to Microsoft’s cloud. Free tier is 5GB, more with a Microsoft 365 subscription.
- Carbonite is a paid, dedicated backup service. It continuously backs up your whole computer (or select folders) to Carbonite’s cloud, separate from Google or Microsoft.
- Total Drive automatically backs up photos and videos to the cloud and syncs files across devices with encryption, similar to what OneDrive and Carbonite already do.
The problem with running all three at once:
- You’re likely paying for overlapping storage (Carbonite + Total Drive).
- Multiple backup tools watching the same folders can cause sync-conflicts, since each program has its own idea of what’s been backed up.
- It’s harder to know where your “real” backup actually lives if something goes wrong.
What I’d suggest:
- Pick one cloud backup for photos/docs.
- Keep OneDrive only if you specifically want Microsoft 365 integration, otherwise turn off its folder backup so it’s not double-syncing.
- Carbonite and Total Drive are largely redundant with each other and with Google. Unless one of them is doing something specific for you (like full-computer imaging, which Google Photos doesn’t do), you can likely drop one.
Combined with your external drives at home, a clean setup would look like: one cloud service + external drive backup, not three cloud services stacked on top of each other.
