Cloud backup services for European businesses
Encrypted on your machine, stored in Europe, immutable while the retention period runs — and billed only for what you occupy.
What a cloud backup service has to get right
Every provider will store your bytes. The differences show up on the day you need the data back, or the day a regulator, an auditor or an attacker asks a harder question. Three properties decide whether a backup is worth having:
It survives the incident
A copy that an attacker can delete with your credentials is not a backup. During the retention period, backups here cannot be overwritten or deleted by anyone.
It stays yours
Encryption runs on your system; the keys never leave it. The provider — including us — holds ciphertext and can neither read your files nor hand them to anyone else.
It comes back
Restores are part of the product, not an upsell: file-level or complete, from any retained version, through the same open-source client. See backup and recovery.
Six questions to ask any provider
Useful whoever you end up choosing. The third column is our answer, so you can hold it against the others.
| Question | Why it matters | lionbackup |
|---|---|---|
| Where is the data, physically? | Jurisdiction follows location and ownership, not the address on the invoice. | European data centres, European providers, zone of your choice |
| Who holds the encryption keys? | Whoever holds them can read the data, or be compelled to. | You. Encryption happens client-side, before upload |
| Can a backup be deleted early? | Ransomware crews delete backups first, using the credentials they already stole. | No — immutable for the whole retention period |
| Is the client auditable? | Encryption you cannot inspect is a promise, not a guarantee. | Open source — read it, build it, verify it |
| How do you get out? | An exit you cannot execute is a lock-in you already have. | Standard formats, documented REST API, no exit fee |
| How is it billed? | Base fees and minimum terms turn a small workload into a large invoice. | Pay-as-you-go on occupied storage; no base fee, no minimum term |
How lionbackup works
Install the open-source client on Windows or Linux, create an access token in the portal, point it at the directories you want and set a schedule. From there it runs on its own: data is encrypted locally, uploaded in chunks that resume after an interruption, and verified on arrival. Large first backups can take days without needing supervision.
What you keep, and for how long, is your retention policy — set per project. While it runs, those versions stay put. The portal shows every run, every restore and every access, and the REST API exposes the same operations for scripting and scheduling.

What it costs
Backup as a service, billed like electricity: no base fee, no minimum term, no per-seat licence. You pay for the storage you actually occupy, and the meter drops when your data does. Current rates are on the pricing page, and the portal shows the running month at all times.
Frequently asked questions
What is a cloud backup service?
A cloud backup service copies your data to a remote data centre on a schedule, so a second copy survives whatever happens to the first: hardware failure, theft, fire, a mistaken delete, or ransomware. The service part matters as much as the storage — scheduling, encryption, retention and restores are what you are actually buying.
How is cloud backup different from cloud storage or file sync?
Sync mirrors your current state, so a deletion or an encryption by ransomware propagates to the copy within minutes. Backup keeps versions and, while the retention period runs, nobody can overwrite or delete them — not you, not us, not an attacker holding your credentials.
Where is the data stored, and who can read it?
In European data centres run by vetted European providers; you choose the zone. Encryption happens on your machine before anything leaves it, and the keys stay with you. We hold ciphertext and cannot read your files.
