- Can I migrate from Backblaze Personal Backup?
- Yes. Start with the workflows or data you actually use, then cut over. The restic / Kopia / Duplicati stack page has the agent prompt and the cost table; most teams rebuild the slice that matters and leave old Backblaze Personal Backup links until they expire.
- How do I deploy it?
- Open the restic / Kopia / Duplicati stack, copy the agent prompt, and deploy on Railway (one service, PORT, and a volume when the app needs disk). 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.
