The short version
Backblaze Personal Backup: Unlimited cloud backup of one computer for a flat annual fee, including external drives. The one paid subscription on this page that most households should genuinely consider, because off-site is the part people skip. Free 15-minute restore window for the first 30 days.

What it is for
Backblaze Personal Backup is a paid, set-and-forget cloud backup that quietly copies your documents, photos and projects to the cloud with unlimited capacity on a single machine. For people who want a safety net without configuring folders and schedules, it removes the excuses.
When to pick something else
It is per-computer and not a file-sync tool, so it is poor for sharing or accessing files across devices in the live sense. The unlimited plan is for personal use, and restores of huge libraries are fastest on a mailed drive, not download.
How it compares in Backup & Sync
These are the alternatives we would consider for the same job. The notes are the same ones used on the main list, so there is no separate ranking hiding on this page.
| Program | Licence / price | Platforms | Why it is on the list |
|---|---|---|---|
| Syncthing Publisher's site ↗ | Free · Open source | Windows, macOS, Linux, Android | Keeps folders identical across your own devices, peer to peer, with no cloud in the middle and no account. Because deletions propagate, it is synchronisation rather than backup. Pair it with versioning turned on. |
| FreeFileSync Publisher's site ↗ | Free · Open source | Windows, macOS, Linux | Compares two folders and shows you exactly what will be copied, moved or deleted before anything happens, then does it and verifies the result. The clearest free tool for mirroring to an external drive. |
| Duplicati Publisher's site ↗ | Free · Open source | Windows, macOS, Linux | Scheduled encrypted incremental backups to a local drive, a NAS or cloud storage, with a browser interface and retention rules. Good for a home setup. Test a restore before you trust it with anything. |
| Restic Publisher's site ↗ | Free · Open source | Windows, macOS, Linux | A single command line binary that does fast, encrypted, deduplicated snapshots to almost any storage backend. The choice for people who want backups they can script and verify rather than click through. |
Practical notes
- Exclude the stuff you do not need to keep costs and time sane.
- Set up a private encryption key so only you can read the backup.
- Test a restore of one file early, so you trust it later.
Questions people ask
Is Backblaze free?
It is a paid subscription; there is a trial period.
Unlimited really?
For a single personal computer, yes, within their fair-use terms.
Is it the same as a sync service?
No, it is backup; use a sync tool for live access across devices.

Where an independent review, audit or survey is mentioned, it is summarised in our own words with the source named and linked; our /sources page sets out that policy. The recommendation, the trade-offs and every 'skip it if' line are our editorial judgement. We do not run benchmarks, publish measured performance figures or host installers, and every download link goes to the publisher's own site.
