Quick answer
Yes — Syncvault is a one-time-purchase alternative to Backblaze Personal. It costs $29 once, while Backblaze Personal runs $9/mo — about $108 per year, every year. Local backup agent that encrypts client-side and pushes to your own S3-compatible bucket or NAS. It is for people who want the job done on their own hardware without a renewal date — not for teams that live inside Backblaze Personal's ecosystem.
The verdict
Switch to Syncvault if you are an individual or small team paying Backblaze Personal $9/mo for work your own machine can do. A 100 GB backup is $29 once plus ~$7/yr of storage versus $108/yr on Backblaze — it pays for itself in about four months, then it's just bytes.
Stay with Backblaze Personal if your workflow depends on its integrations, you need enterprise features (SSO, admin controls, SLAs), or your team is large enough that per-seat collaboration tooling is worth the bill. Syncvault does not try to replicate those.

Where Backblaze Personal still wins
- Ecosystem and integrations. Established tools accumulate years of third-party integrations, templates and add-ons. If your workflow is wired into Backblaze Personal's ecosystem, switching means rebuilding that plumbing — a real cost.
- Team and enterprise features. Shared workspaces, granular permissions, SSO, audit logs and a vendor to call when something breaks — that is what the higher subscription tiers actually buy, and a pay-once app does not come with it.
- Familiarity and hiring. Backblaze Personal is the name people already know. Onboarding a team onto a tool nobody has used before takes time the subscription never charges for.
Where Syncvault wins
- Price, permanently. $29 once versus $108/yr for as long as you use it. There is no renewal, no seat count and no tier gate.
- Client-side AES-256-GCM. Key is derived from your passphrase with scrypt, never uploaded and never stored in plaintext.
- Content-addressed dedupe. Objects are keyed by SHA-256 of content, so identical or unchanged files upload exactly once.
- Point-in-time versioning. Keep the last N versions of every file and browse the backed-up tree as of any point in time to restore.
The math
A 100 GB backup is $29 once plus ~$7/yr of storage versus $108/yr on Backblaze — it pays for itself in about four months, then it's just bytes.
- After 1 year: Syncvault has cost you $29 total — Backblaze Personal has cost $108.
- After 3 years: Syncvault is still $29 — the subscription is at $324.
- After 5 years: Syncvault is still $29 — the subscription is at $540.
Common questions
Is it really free on GitHub?
Yes — Syncvault is MIT-licensed at github.com/bensblueprints/data-backup-cloud-sync-mvp. The $29 buys the signed Windows installer and 1-click setup; building from source is free.
What happens to my data if I stop using Syncvault?
Nothing is locked up. The SV1 file format is documented, and your data is recoverable with ~20 lines of Node — no vendor lock-in, even from us.
Do you ever see my files or my key?
No. Encryption is client-side, the key never leaves your machine, and the index is a local SQLite file with zero telemetry.
