what AI can build

Continuously back up selected folders, encrypt files client-side, track versions, restore them from user-owned object storage, and test restores regularly.

A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Backblaze Personal Backup, continuously back up a selected computer to user-owned object storage and test restores. The hard boundary is unlimited backup economics, client reliability, restore logistics, support, and durable infrastructure, plus reliability, durability, and cross-device sync.

The honest tradeoff

who should keep paying

People still pay for Backblaze Personal Backup because storage subscriptions sell confidence that files will still exist after a lost device, bad sync, or provider incident. The recurring cost buys chunking, encryption, conflict detection, versions, garbage collection, bandwidth, restore drills, monitoring, billing, and disaster recovery, not just the visible interface.

the prompt

Curated prompt
Build a closest honest personal substitute for Backblaze Personal Backup in an empty repository.
Use Next.js 15, TypeScript, PostgreSQL, MinIO, and a Tauri 2 sync client; do not offer alternative stacks.
The core loop is: continuously back up selected folders, encrypt files client-side, track versions, restore them from user-owned object storage, and test restores regularly.
Make the first run work locally with one documented command.
Store all user data locally by default and make export straightforward.
Put secrets in .env, ship .env.example, and never commit credentials.
Build a desktop client that watches explicitly selected folders and ignores configured patterns.
Chunk, hash, compress, and encrypt files locally before uploading to the configured object store.
Store version metadata, tombstones, device identifiers, and integrity checks in PostgreSQL.
Provide upload and restore queues with pause, retry, bandwidth limits, and resumable transfers.
Add file history, point-in-time restore, key export, storage usage, and scheduled restore tests.
Document the failure model and make clear that one server is not a complete backup strategy.
Include clear empty, loading, success, and recoverable error states.
Add input validation, safe filenames, and graceful handling of unavailable APIs.
Write focused tests for the core transformation and one end-to-end happy path.
Create a README with setup, architecture, permissions, data location, and backup steps.
Do not add accounts, billing, telemetry, analytics, or a hosted control plane.
Do not claim to reproduce proprietary data, network liquidity, regulated access, or frontier infrastructure.
Deliberately leave out multi-provider consumer sync at global scale.
Deliberately leave out guaranteed durability or ransomware recovery.
Deliberately leave out shared-drive administration, mobile apps, and enterprise compliance.
Finish by running the tests and listing the exact commands used.

How much does Backblaze Personal Backup cost?

Backblaze Personal Backup is listed at about $9/month (Computer Backup, checked 2026-07-31), or $108 per year. This is a pricing reference, not evidence of a completed replacement or realized savings.

What do I lose by replacing Backblaze Personal Backup?

Honestly: unlimited backup economics, client reliability, restore logistics, support, and durable infrastructure; global sync network; battle-tested conflict resolution; ransomware recovery guarantees; mobile clients and support. If any of those are load-bearing for you, keep paying.

Is there an open-source alternative to Backblaze Personal Backup?

Yes — Nextcloud (Mature open-source file sync and collaboration server.). Using prior art is also a valid exit; the prompt is for when you want it exactly your way.
