Ask Rubix Backup a question. Answers come from this site's docs only. I will cite a page. I will not invent a product claim.
Security
What the server sees — and what it does not
Self-hosted backup with a clear boundary: ciphertext in safes, optional E2E so keys stay with you.
Encrypted-at-rest safes
Backup chunks land in safes protected with AES-256-GCM. Storage is deduplicated. You own the host and the disks.
E2E mode
In end-to-end mode, rubixd does not hold plaintext backup contents or the keys needed to decrypt them. A compromised backup server yields ciphertext and metadata, not readable files.
Self-hosted, not SaaS backup
Rubix Backup is software you run. This product is not a Rubix-hosted SaaS backup service.
Honest scope
We do not claim HIPAA or SOC 2 certification here. Windows coverage is VSS volumes; Linux coverage is file trees. Peer replication is not presented as complete.
