Both offer unlimited backup for one computer. One feels modern; the other feels its age. Here’s the split.
| Service | Score | Best for | Price |
|---|---|---|---|
| Backblaze | 9.2 ★★★★★ | Best for set-and-forget | From $9/mo per computer, unlimited |
| Carbonite Safe | 7.6 ★★★★☆ | The old reliable | From ~£5/mo |
For almost everyone, Backblaze — it’s cheaper, faster and simpler, with the handy restore-by-post option. Carbonite is fine and familiar, but it’s slower and dated. Unless you already know and trust Carbonite, Backblaze is the pick.
