# restic / Kopia / Duplicati

Backups you encrypt. restic is BSD-2-Clause; Kopia is Apache-2.0; Duplicati's root LICENSE is MIT — Backblaze Personal Backup without the vendor vault as the only copy.

**Replaces:** Backblaze Personal Backup

**Tier:** Easy

## Problem

Backblaze Personal Backup is a consumer backup subscription to their cloud. You wanted encrypted snapshots on a disk or bucket you control. restic is BSD-2-Clause. Kopia is Apache-2.0 with a GUI. Duplicati's root LICENSE is MIT (proprietary/ if present is separate). BorgBackup is a 3-clause BSD-style archiver already on /best/backup. This is not Backblaze B2 object storage (/replace/aws-s3) and not a file-sync share (/replace/dropbox). Restore one file as the test. Do not invent a restore-success rate.

## Stack

- [restic](https://restic.net) — BSD-2-Clause encrypted backup program
- [Kopia](https://kopia.io) — Apache-2.0 snapshots with client-side encryption and a GUI
- [Duplicati](https://duplicati.com) — MIT-licensed (root LICENSE) backup app with a web UI

## Estimated SaaS cost saved

| You stop paying | Typical / year | Self-host instead |
|---|---:|---|
| Backblaze Personal Backup (household) | $1,200 | restic, Kopia, or Duplicati |

**About $1,200 / year** on a small team, before you count lock-in.

## Deploy on Railway

Placeholder: restic/Kopia/Duplicati run as a job against a volume or S3-compatible bucket you already have. A single public website is the wrong shape. No one-click template in this repo yet — Start on Railway. Object storage stays on /stacks/minio-object.

[Start on Railway](https://c17.io/go/railway/restic-backup?from=%2Fstacks%2Frestic-backup.md)

[Garage / MinIO if this is the S3 bucket, not the backup client](https://c17.io/stacks/minio-object)

## AGENT_PROMPT

```
Replace Backblaze Personal Backup with restic (CLI), Kopia (GUI), or Duplicati (web UI).

- Persist the repository. Encrypt it. Restore one file as the test. The destination can be a volume, another disk, or S3-compatible storage you already run.
- This is not B2 as a product page (/replace/aws-s3). Write AGENT_PROMPT.md.
```

## FAQ

### restic or Kopia?

restic if you want the small CLI. Kopia if you want snapshots plus a GUI. Duplicati if you want a web UI. Pick one repository format on day one.

### Is this Backblaze B2?

No. B2 is object storage — /replace/aws-s3. This page is the backup client. You can point restic at B2 or at a bucket you host.

### Where do the blobs go?

A volume, an S3-compatible store (/best/object-storage), or another disk you own.
