Ransomware, regulatory compliance, disaster recovery plan (DRP) or business continuity plan (BCP): there is no shortage of reasons to offsite your Proxmox backups. The rule is simple: if your backups are on the same infrastructure as your production, you are one incident away from losing everything. Offsite backup means delegating the storage of your backups to a specialized provider, with security, availability and sovereignty guarantees. But at what cost? This guide details the approaches, selection criteria and pricing of the main solutions on the market.
Different offsite approaches
Before comparing prices, it is essential to understand the three main families of solutions for offsite Proxmox backup.
Self-hosted remote
You manage your own remote server dedicated to backup. This involves purchasing hardware (server, disks), renting datacenter space, physical and software maintenance, and bandwidth management. Initial cost is high and hidden expenses (electricity, disk replacement, admin time) accumulate rapidly.
Public cloud (AWS S3, Azure Blob, GCP)
Hyperscalers offer on-demand object storage, billed per usage. The model is flexible, but egress costs (data retrieval) can skyrocket during a restore. Additionally, data sovereignty remains a sensitive topic: your backups transit through American infrastructure subject to the Cloud Act. Configuration complexity and cost optimization are also significant.
Specialized provider (NimbusBackup)
Turnkey solution: the provider manages infrastructure, security, maintenance and support. Hosting is French, support is French-speaking and Proxmox-specialized. Pricing is predictable, with no hidden egress or restore fees.
Outsourcing to a specialized provider combines the best of both worlds: the simplicity of cloud with the sovereignty and expertise of dedicated French hosting.
Selection criteria for offsite backup
Not all providers are equal. Here are the determining criteria for choosing your offsite Proxmox backup solution.
Data location
Hosting in France or the EU to guarantee GDPR compliance and data sovereignty. Avoid providers subject to extra-European legislation.
Security
Client-side AES-256 encryption, physical air-gap, data immutability. These three pillars guarantee protection of your backups against ransomware.
Supported protocols
Native PBS for Proxmox, AWS-compatible S3 API, iSCSI, rsync, SFTP, WebDAV. Protocol diversity ensures compatibility with your existing infrastructure.
Technical support
Responsive, Proxmox-specialized support makes all the difference in case of an incident. Choose a provider who knows your ecosystem.
SLA and availability
Contractual availability guarantees, redundant infrastructure, commitments on restore times (RTO/RPO).
Scalability
Easy capacity scaling without service interruption. Your data volume grows: your backup solution must keep up.
Detailed NimbusBackup pricing grid

12 EUR/TB/moBackup on Meca disk, AES-256 encryption, hosted on 1 site in France. The ideal entry-level plan to secure your Proxmox backups.
Double Drive PBS
22 EUR/TB/moGeo-redundancy across 2 separate sites in France, automatic replication. Protection against complete datacenter loss.
AirGapped Drive PBS
34 EUR/TB/moPhysical disk rotation with 2 weeks of data permanently offline. Anti-ransomware protection through physical isolation.
Drive Bank PBS
69 EUR/TB/moBank vault for maximum isolation. Your disks are stored in a secure physical vault, inaccessible digitally.
Magnetic PBS
89 EUR/TB/moHDD + automatic LTO tape archiving for 30+ year durability. The ideal solution for long-term regulatory archiving.
Magnetic Bank PBS
149 EUR/TB/moLTO in bank vault: the highest level of compliance and security available. Recommended for entities subject to NIS2 or the strictest requirements.
Direct Storage Plans (multi-protocol)
Our direct storage solutions are compatible with all backup tools on the market: Veeam, Acronis, rsync, or any software supporting iSCSI, SFTP, WebDAV or rsync.
DirectDrive
12 EUR/TB/moMulti-protocol direct storage: iSCSI, rsync, SFTP, WebDAV. Veeam compatible and all backup tools on the market.
DirectMagnetic
18 EUR/TB/moDirect storage + automatic LTO tape archiving within 48h. Double protection: online disk and offline tape.
S3 Storage Plans
Our S3 Storage plans provide a 100% AWS S3-compatible API. Ideal for cloud-native applications, automated scripts or integration with third-party tools.
Cost comparison: self-hosting vs outsourcing
To objectively evaluate the real cost of each approach, let's take the example of an SMB with 2 TB of Proxmox backups to offsite over 3 years.
Remote self-hosting
- Dedicated server (purchase)~1,500 EUR
- Meca disks 2 TB (RAID)~500 EUR
- Datacenter colocation (36 months)~3,600 EUR
- Electricity (36 months)~1,800 EUR
- Maintenance (~5h/month x 36)~9,000 EUR
- Dedicated bandwidth~1,080 EUR
- 3-year total~17,480 EUR
NimbusBackup outsourcing
- Single Drive PBS (2 TB x 36 months)864 EUR
- Double Drive PBS (2 TB x 36 months)1,584 EUR
- AirGapped Drive PBS (2 TB x 36 months)2,448 EUR
- Hardware investment0 EUR
- Maintenance / administration0 EUR
- Egress / restore fees0 EUR
- 3-year total (depending on plan)864 - 2,448 EUR
For most SMBs, outsourcing to a specialized provider costs less than self-hosting once you factor in hidden costs: electricity, maintenance, disk replacement, admin time.
