The short version
Restic: 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.

What it is for
Restic is a free, open-source command-line backup tool that encrypts, de-duplicates and versions snapshots to local or remote storage, including cloud. For users comfortable with a terminal, it is fast, trustworthy and scriptable, which makes it ideal for automated server and desktop backups.
When to pick something else
It is command-line first, so there is no friendly wizard; newcomers need to read the docs and write a small script. It is a backup tool, not a sync tool, so it will not mirror a live working folder the way a sync client does.
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. |
| Backblaze Personal Backup Publisher's site ↗ | Paid · From $99/year | Windows, macOS | 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. |
Practical notes
- Script the backup and forget command, then schedule it.
- Store the repository password somewhere safe; losing it loses the backup.
- Occasionally run snapshots and forget to prune old data.

How to read this page. How to read this page. Platform, licence and publisher details come from our directory data. 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.
