A Rubrik alternative (for the part that concerns you)
Rubrik is consistently ranked among the leaders in enterprise backup: Zero Trust architecture, immutable backups, anomaly detection, and a ransomware recovery warranty reaching up to $10M for some editions. It's a serious platform, built for large organisations in regulated sectors.
It is also, by construction, a complete overhaul of your backup chain — with the budget that goes with it: entry-level configurations (three-node appliance) are cited at around $100,000, and the model remains enterprise-oriented, with pricing that is rarely public and licensing that users describe as complex.
Two different problems
It's worth separating two needs that enterprise marketing happily blends together:
- "I want a new backup platform": replace my tooling with an integrated solution (backup + immutability + detection + recovery). That's what Rubrik, Commvault and Cohesity are for.
- "I want to prove my current backups restore": keep my stack (pg_dump, mysqldump, scripts, S3, Restic, whatever) and get continuous, auditable proof of restorability.
If you're in case 2, buying a case-1 platform is like replacing the whole kitchen because you were missing a thermometer.
What RestoreProof does
RestoreProof doesn't replace your backup — it puts it to the test, automatically, and produces the evidence:
- Real test restores: a runner on your infrastructure fetches the backup (S3 and compatibles, HTTP, local or NFS), restores it into ephemeral Docker containers (PostgreSQL, MySQL, MongoDB, SQLite, PocketBase, LDAP), and validates the data: archive integrity, canary files, queries with thresholds, X.509 certificate, HTTP probes.
- Cryptographic evidence: every test produces a timestamped report signed with Ed25519. The private key stays on your runner; the report is tamper-proof. Exactly the kind of evidence expected in a NIS2 or ISO 27001 (A.8.13) audit, or by a cyber insurer.
- Sovereignty: data and secrets never leave your infrastructure. The SaaS only receives signed verdicts. No appliance, no replication of your data to a third-party cloud.
- Deployment in minutes: a Docker container, or the Helm chart on Kubernetes. No rack to cable, no six-month migration project.
- Public pricing: Free / €49 per month / €149 per month, billed annually (€59 and €179 monthly). Prices exclude VAT.

Who is each for?
Rubrik makes sense if: you're a large organisation, you want to consolidate backup, immutability and ransomware detection into a single platform, and your budget is that of a cyber-resilience programme.
RestoreProof makes sense if: your existing backup works (or you believe it does), what you're actually missing is verifiable proof that it restores, and you want it this week rather than at the next budget cycle.
FAQ
Does RestoreProof provide backup immutability like Rubrik? No — that isn't its role. Immutability protects the copy; RestoreProof proves the copy is usable. The two are complementary: S3 object lock from your storage provider on the immutability side, RestoreProof on the restorability-evidence side.
Can RestoreProof be used alongside an enterprise platform? Yes. Because RestoreProof is source-agnostic, it can test backups produced by any tool as long as they're reachable (S3, HTTP, file) in a supported format — and provide signed evidence that is independent of the backup vendor, which has value of its own in an audit.
