What Arx One does
Arx One is a French software company founded in 2009 and headquartered in Nantes, with a technical development and infrastructure office in Lyon. The company develops, operates, and supports Arx One Backup, a proprietary backup software platform built entirely in-house using Microsoft .NET (C#), Rust, Visual Studio, and Git/GitLab. The platform supports Windows, Debian Linux, macOS, Synology DSM, QNAP QTS, Hyper-V, Proxmox, SQL Server, and HFSQL environments, and is delivered in three deployment modes: externalized (fully managed cloud backup hosted in geo-redundant French datacenters in Nantes and Lyon), centralized (on-premise software with customer-managed storage), and On Box (local backup on customer-owned non-proprietary hardware). Recent product additions include native Proxmox VE support (mid-2024), Microsoft 365 cloud-to-cloud backup covering Outlook, OneDrive, and SharePoint with Teams and Entra ID scheduled, and Bare Metal Restore capability launched in 2026-04. The company also operates a Seafile-based sub-brand, Partage Collaboratif, for open-source collaborative file sharing.
Arx One monetizes through three subscription/usage-based revenue streams: externalized backup billed on volume consumed, on-premise software licensed on a volume basis, and partner-program consumption billed across all of a partner's machines and end customers. Distribution is 100% indirect through a network of more than 90 French IT integrator, MSP, and reseller partners who receive training, marketing kits, and free white-label capability, supplemented by participation in IT Partners, the FRP2i convention, Cybernight awards, and webinars. Pricing is pay-as-you-go with no setup fees, and white-label is offered at no charge to partners.
Arx One serves healthcare providers (hospitals, doctors, IPN Paris, PariSanté Campus, La Colline), SMBs (TPE/PME), large enterprises (Brinks, id verde, Orqual, Ondif, Timcod, VM Matériaux, ANTEA, Envoliis), the public sector via UGAP, software publishers, and the education and culture verticals (HEC Paris, Théâtre du Châtelet). The company holds HDS (Hébergeur Données de Santé) certification across all six levels of its offering plus ISO 27001, is a French Tech Nantes member, and claims 100% data restoration success across its 8,000+ user base since the service's 2009 inception. Ownership is concentrated in co-founders Romain Craponne and Pascal Craponne, with no disclosed external funding, parent company, or institutional investment.

Arx One competitors and assessment
Company assessmentDirect peers
- NAKIVO: NAKIVO provides backup solutions for virtual, physical, cloud, and SaaS environments targeted at SMBs and MSPs. Competes head-to-head with Arx One in Proxmox, Hyper-V, and Microsoft 365 backup.
- Altaro (Hornetsecurity): Altaro (now part of Hornetsecurity) targets the same SMB and MSP segment with VM backup (Hyper-V, VMware) software sold largely through IT resellers. Closely matches Arx One's channel-led, SMB-focused model.
- Acronis: Acronis provides integrated backup and cyber protection software for SMBs, MSPs, and enterprises — directly comparable to Arx One's combined backup + ransomware protection offering. Acronis has a strong partner/MSP channel globally.
Emerging players
- Owncloud / Nextcloud: Nextcloud (and ownCloud) are open-source sovereign file sharing and collaboration platforms. Arx One's Seafile/Partage Collaboratif offering competes in this adjacent sovereign collaboration category.
- Datacore Software: Datacore provides storage virtualization and data protection software for enterprise and midmarket customers, overlapping with Arx One's centralized and hybrid backup scenarios.
Broad incumbents
- Datto (Kaseya): Datto, owned by Kaseya, is a major MSP-focused backup and business continuity vendor. Its SIRIS product competes with Arx One's MSP-oriented backup offer and shares the channel-driven GTM model.
- StorageCraft / Arcserve: Arcserve (parent of StorageCraft) provides backup, disaster recovery, and ransomware protection for SMBs and enterprises — directly overlapping with Arx One's core backup and BMR positioning.
- Veeam Software: Veeam is the dominant enterprise backup software vendor with extensive SMB and MSP coverage. It competes directly with Arx One Backup in VM backup (Hyper-V, VMware), and is the primary incumbent Arx One's channel partners likely also offer.
- Cohesity: Cohesity is an enterprise data protection and management platform with growing SMB and ransomware-protection offerings. While more enterprise-focused, it competes in adjacent backup and data security categories.
Regional players
- OVHcloud: OVHcloud is the leading French/European sovereign cloud provider and offers backup and hosted private cloud services. Competes in the French sovereign infrastructure layer that underpins Arx One's externalized backup offer.
