Detailed comparison
Two Proxmox Backup Server hosts, two approaches. Remote-Backups.com, a German service, sells the PBS datastore at €8.50 excl. VAT/TB/month and charges separately for immutability and geo-replication. Nimbus (NimbusBackup, by RDEM Systems), network operator AS206014, starts at €12 excl. VAT/TB/month and goes all the way to offline copies: unplugged disk, LTO tape, bank vault. As long as protection stays online, Remote-Backups is cheaper. The real question is whether you need an offline copy.

Nimbus (NimbusBackup): network operator and offline copies
NimbusBackup is the backup brand of RDEM Systems, a human-scale managed services provider and autonomous network operator under AS206014. Its backup servers are in its own racks in the Equinix Paris datacenter (Tier III equivalent) or rented from major French or European hosting companies (such as OVH). The range goes from online disk to bank vault, every plan at a public price.
What sets Nimbus apart is not the price per TB: it is the option to add a physically offline copy — unplugged disk, LTO tape, bank vault — with the same provider.
Nimbus strengths:
- Own network (AS206014): autonomous operator, 3 transit providers, 5 internet exchanges (IX), and peering via France-IX, Hopus, DE-CIX, AMS-IX and LINX for servers hosted in-house
- Equinix Paris, Tier III equivalent: redundant power and cooling, physical access control
- Public price range: from Single Drive (€12/TB) to Magnetic Bank (€149/TB)
- Write-only client account: by default, the credentials provided can back up, not delete
- Offline copies: unplugged disk (AirGapped Drive), LTO tapes, up to the bank vault
- French provider: contract under French law, French-speaking support

Remote-Backups.com: PBS hosted in Germany, à-la-carte options
Remote-Backups.com is a German service, hosted across several sites in Germany. The PBS datastore costs €8.50 excl. VAT/TB/month, billed in 100 GB increments, with a 500 GB minimum (€4.25/month) and up to 20 TB per datastore. Two options come on top: immutability, from €3/TB/month on the data actually stored, and geo-replication, €4/TB per copy per month, up to three copies. The service also accepts Proxmox VE, Borg, SFTP and Synology NAS.
Remote-Backups strengths:
- Price: €8.50 vs €12 excl. VAT/TB/month for the Nimbus entry plan, about 29% less
- Immutability as an option: a second read-only datastore, synced by a job whose credentials you do not hold
- Geo-replication: up to three copies on other sites, billed hourly
- Multi-protocol: Proxmox VE, Borg, SFTP and Synology on top of PBS
- Resellers: pricing from €7/TB with API access
Note: Remote-Backups' immutability is an online copy, on the same server by default (on another site if you add geo-replication). No unplugged disk, LTO tape or vault option is offered as of the check date. The 100 GB free tier is currently closed to new sign-ups.
Detailed comparison table
Here is a point-by-point comparison of both solutions to help you evaluate each criterion objectively:
Pricing compared, protection level by protection level
On disk only, Remote-Backups has a clear price advantage. Direct comparison at equal volume:
Per TB, Remote-Backups costs €8.50 vs €12 excl. VAT/month, about 29% less. The gap holds with two sites: €12.50 vs €22 excl. VAT/TB/month (Remote-Backups geo-replication vs Nimbus Double Drive). As long as every copy stays online, Remote-Backups is cheaper at each level. The difference in range starts with the offline copy: €34 excl. VAT/TB/month for the Nimbus AirGapped Drive, with no equivalent at Remote-Backups.
With comparable protection against deletion, the gap narrows: €11.50 excl. VAT/TB/month at Remote-Backups (€8.50 + the €3 immutability option, billed on actual data) vs €12 at Nimbus, where the client account is write-only by default. The mechanisms differ: Remote-Backups keeps a separate copy with its own retention; Nimbus prevents deletion from the account provided to the client.
What the price gap pays for at Nimbus:
- A write-only client account by default, with no option to pay for
- A network run in-house under AS206014 (3 transit providers, 5 internet exchanges)
- Owned infrastructure in the Equinix Paris datacenter (Tier III equivalent)
- French-speaking support and a contract under French law
- The option to move up to an offline copy, LTO air gap or the bank vault without changing provider
Remote-Backups offers reseller pricing from €7/TB with API access. Nimbus offers a white-label plan, and volumes over 3 TB are handled on quote. Contact us for a custom quote.
Immutable is not offline
When ransomware strikes, the question is not "how much am I paying per TB" but "are my backups intact and recoverable?".
Remote-Backups answers with its immutability option: a second read-only datastore that your own credentials cannot modify. It is real protection against deletion with stolen credentials, and it is cheap. But that copy stays online, reachable over the network and run by the same provider.
Nimbus starts from a write-only client account by default: stolen credentials can write, not delete existing backups. Then Nimbus adds the next layer: a physically disconnected copy. From Single Drive for daily backups to AirGapped Drive (unplugged disk) and Magnetic Bank (LTO tape in a bank vault), each level adds a layer of physical protection.
Online ≠ offline. A read-only copy is still reachable over the network. A physically offline copy — unplugged disk or LTO tape — is out of reach of a network attack. France's ANSSI deems an offline backup indispensable (backup guide, R12).
Location, contract and regulation
Both services host inside the European Union: GDPR applies to both. Remote-Backups hosts in Germany. Nimbus's backup servers are in its own Equinix Paris racks or rented from major French or European hosting companies (such as OVH); hosting in France on request. No transfer outside the EU by default; a US datastore is possible on express request (exposed to US law).
NIS2 does not require hosting in France. It requires risk-management measures — including backups and testing them — and control of your supply chain. What matters: who your contracting party is, where the copies are, who can access them, and whether one copy is offline.
Nimbus is run by RDEM Systems, a French company: contract under French law, French-speaking support, compatibility with a managed Proxmox infrastructure. If your procurement policy requires a provider under French law, that is an objective criterion. Otherwise, location is not a compliance argument.
Simplicity and onboarding
Remote-Backups plays the simplicity card: a single price per TB, options to tick, an online storage estimator and a 7-day trial. The approach works well for administrators who want an online offsite backup without overthinking it.
Nimbus offers more levels, which can look more complex at first. The interactive configurator guides the choice based on your needs. Measured provisioning times: 80% of requests within 4 business hours, 95% within 8 business hours; over 3 TB, the lead time is confirmed in the quote. The 7-day free trial on request, up to 2 TB, lets you validate the solution before committing.
Who should choose what?
Choose Remote-Backups if:
- Price per TB is your main criterion
- Online protection is enough, with immutability or geo-replication as options
- You also back up with Borg, SFTP or from a Synology
- You resell backup (reseller pricing, API)
Choose Nimbus if:
- You want a physically offline copy (unplugged disk, LTO, bank vault)
- Your procurement policy requires a provider under French law
- You want a provider that runs its own network (AS206014) and hosting (Equinix Paris)
- You plan to move up in protection without changing provider
- French-speaking support matters to you
Frequently asked questions
Our verdict
Remote-Backups is a solid, cheaper option for backing up a PBS online, and its immutability and geo-replication options now cover a good share of everyday needs. Nimbus makes sense when you need a physically offline copy — unplugged disk, LTO tape, bank vault — or a French provider that runs its own network. The entry-level gap, €12 vs €8.50 excl. VAT/TB/month, pays for that range and that infrastructure.
