The PBS as a Service market is splitting into two models: fully managed backup and self-service multi-tenant platforms. Nimbus (NimbusBackup, by RDEM Systems) is a managed PBS provider operating its own autonomous network (AS206014), while Requiesco.cloud is a self-service PBS reseller hosted on third-party infrastructure (OVHCloud, Scaleway, Hetzner). The PBS reseller vs the network operator — this comparison helps you choose objectively.

Nimbus (NimbusBackup): managed premium backup on own infrastructure
NimbusBackup is the backup brand of RDEM Systems, an autonomous network operator under AS206014. Unlike self-service platforms, Nimbus is fully managed: RDEM Systems handles infrastructure, monitoring, and maintenance. You just configure proxmox-backup-client on your Proxmox VE nodes.
Nimbus is the only managed PBS provider to operate its own autonomous network (AS206014), ensuring full control over connectivity and latency.
Nimbus key strengths:
- Fully managed: no Web GUI to learn, no infrastructure to maintain — RDEM Systems handles everything
- Own infrastructure (AS206014): autonomous network, direct BGP peering with Free, Orange, SFR
- Equinix Paris, Tier IV equivalent: world-class datacenter, redundant power, maximum physical security
- Bank vault air gap: LTO tapes physically transported off-datacenter, true air gap
- Transparent public pricing: all offerings (Single Drive, Magnetic, AirGapped LTO, Bank) with published prices
- Fast delivery: 80% of requests within 4 business hours, 95% within 8 business hours

Requiesco.cloud: self-service PBS as a Service
Requiesco.cloud is a self-service PBS platform hosted near Paris, France, on rented infrastructure from OVHCloud, Scaleway, and Hetzner. It offers three tiers: Shared, Dedicated, and Enterprise, with a multi-tenant architecture designed for resellers and MSPs.
Requiesco key strengths:
- Low entry price: Shared tier at €9.99/TB makes it one of the cheapest PBS options
- Multi-tenant architecture: Enterprise tier designed for resellers with unlimited namespaces
- Web GUI (Dedicated/Enterprise): self-service management interface for datastore administration
- Enterprise high resilience: dRAID-2+ storage, 24/7 priority support, 8TB starting at €400/mo
Note: Requiesco's Shared tier has significant limitations: no Web GUI, single namespace only, and no RAID protection. The Dedicated tier at €30/TB includes Web GUI and RAIDZ-1+ but costs 2.5x the Nimbus Single Drive equivalent. Enterprise requires a 6-month commitment.
Detailed comparison table
Here's a point-by-point comparison to help you objectively evaluate each criterion:
Pricing comparison: tier by tier
Requiesco's three tiers compared to Nimbus Single Drive (entry-level managed PBS):
Requiesco's Enterprise tier starts at €400/mo for 8TB (€50/TB), with dRAID-2+, 24/7 priority support, and a 6-month commitment. This tier is designed for resellers and MSPs.
While Requiesco Shared is €2 cheaper per TB, it lacks RAID, Web GUI, and multi-namespace support. At the Dedicated tier (€30/TB), Nimbus is 2.5x cheaper for comparable features.
Advanced Nimbus offerings (not available from Requiesco):
- Magnetic PBS (disk + LTO tape): €89/TB/mo
- AirGapped LTO PBS (LTO tape in DC safe): €119/TB/mo
- Magnetic Bank PBS (disk + tape + bank vault): €149/TB/mo
Requiesco is disk-only. There is no LTO tape backup, no air gap, and no off-site vault storage option. Data replication is available but doubles the price (+100%).
Infrastructure and sovereignty
The fundamental difference between Nimbus and Requiesco lies in the infrastructure model. Nimbus operates its own autonomous network (AS206014) and owns hardware in the Equinix Paris datacenter, a globally recognized Tier IV equivalent facility. Requiesco rents all its servers from OVHCloud, Scaleway, and Hetzner.
This has a concrete impact: direct BGP peering with French ISPs (Free, Orange, SFR) allows Nimbus to control latency and bandwidth end-to-end, which is critical for implementing a reliable multi-site Proxmox DRP. Data doesn't traverse a third-party hosting provider's intermediate networks.
Requiesco's self-service model means you manage your own datastores through the Web GUI (on Dedicated/Enterprise tiers). This gives more hands-on control but also more operational responsibility. Nimbus's managed model means RDEM Systems handles all infrastructure concerns, letting you focus on your core business.

Security and air gap: the key differences
An air gap is a security measure that physically isolates a storage medium from any computer network. It's the ultimate protection against ransomware and cyberattacks, and a key requirement for NIS2/ISO 27001 compliance.
Nimbus offers true physical air gap: LTO tapes are physically transported and stored in a bank vault, completely disconnected from any network. The AirGapped LTO PBS and Magnetic Bank PBS plans include this protection with public pricing.
Requiesco is disk-only. There is no LTO tape backup and no air gap option. Data replication is available (+100% price) but replication is not air gap — both copies remain online and accessible from the network.
Disk replication is not air gap. If an attacker compromises the primary server, replicated data on another online server is equally at risk. Only physically disconnected media (LTO tape in a bank vault) guarantees complete isolation from cyber threats.
Delivery and onboarding
Nimbus commits to specific delivery times: 80% of requests processed within 4 business hours and 95% within 8 business hours. Once the datastore is delivered, backup is operational in 5 minutes: just add the PBS storage in Proxmox VE and launch your first backup job. This managed approach integrates seamlessly into a broader DRP/BCP and managed services strategy.
Requiesco operates as a self-service platform: you sign up, choose your tier, and configure your datastore through the Web GUI (Dedicated/Enterprise). The onboarding is hands-on — you manage namespaces, users, and storage yourself. On the Shared tier, there is no Web GUI, so configuration is done via CLI only.

Who should choose what?
Choose Requiesco if:
- You're an MSP/reseller needing multi-tenant self-service (Enterprise tier)
- You want the absolute cheapest per-TB pricing and can accept no RAID (Shared)
- You prefer hands-on Web GUI management of your datastores
- Air gap / LTO tape backup is not a requirement
Choose Nimbus if:
- You want a fully managed service with no operational overhead
- Sovereignty and infrastructure control are priorities (own AS206014)
- You need physical air gap with bank vault storage
- You want competitive pricing with RAID included on all plans (€12/TB)
- You prefer a Tier IV equivalent datacenter (Equinix Paris)
Frequently asked questions
Our verdict
Requiesco targets MSPs and resellers with its self-service multi-tenant architecture, while Nimbus offers a fully managed premium experience on its own infrastructure (AS206014). At €12/TB with RAID included, Nimbus is more cost-effective than Requiesco Dedicated (€30/TB) and includes air gap LTO options that Requiesco simply does not offer. The choice depends on whether you need self-service control or prefer a managed, hands-off backup solution.
