lionbackup

lionbackup is a cloud backup service for businesses and teams. Data is backed up through a lightweight client, optionally end-to-end encrypted on the customer's own system, and transferred to geographically distributed storage zones in Europe. Everything is managed through a customer portal with organizations, projects and access tokens.

At a glance​

  • Client-side encryption. Backups can be encrypted before they ever leave the customer's system. The client-side keys remain exclusively with the customer; lionbackup only ever receives the content as ciphertext.
  • Sovereign data storage in Europe. Data is stored in data centres in Europe, spread across several providers and locations. You choose the region your data lives in.
  • Immutable, write-protected storage (WORN). Projects configured accordingly store backups immutably for the chosen retention period — protection against accidental or malicious deletion, e.g. in ransomware incidents. Reading is done exclusively via a separate token with read permission (see Lifecycle of a backup).
  • Multi-tenant portal. Organizations, projects, roles, tokens and billing in one place, with single sign-on and multi-factor authentication.
  • Open-source client. Backups run through a lightweight client written in Go for Linux and Windows, whose source code is publicly available.

How the platform is built​

lionbackup is divided into a central Business Zone and several mutually isolated Storage Zones. The Business Zone runs the portal, the management API and central services; the Storage Zones receive the encrypted backups through so-called Citadels. The actual uploads go directly to the Citadels and do not pass through the Business Zone.
