Leviia

What Leviia actually is

Leviia is a French cloud provider selling one thing this listing cares about: Storag3, an S3-compatible object storage service hosted exclusively in France and priced as a single flat number. The company — Leviia SAS, run by brothers William Méauzoone (CEO) and Arnaud Méauzoone (CTO) — began building in 2019, incorporated in late 2020, and launched the object-storage line in February 2023. The pitch is narrow and deliberate: keep every byte on French territory, under French law, away from US extraterritorial legislation like the Cloud Act and FISA, at a price that does not punish you for reading your own data back.

The product name has changed with the infrastructure. The original Leviia Object Storage ran on OVHcloud data centers in Roubaix, Gravelines, and Strasbourg; since 2024 the service runs on Free Pro data centers, with three sites in Lyon and Marseille, and was relaunched as Storag3 with ISO 27001 and HDS certifications behind it. HDS — the French health-data hosting certification — is the one that carries weight beyond healthcare, because it mandates access traceability and regular audits. Leviia leans into that: every access and action on stored data is timestamped, attributed to a named identity, and auditable, which is the kind of claim that is expensive to fake.

The company reports more than 1.5 million users across its services and over 500 companies and public-sector organizations on Storag3, with references including the Île-de-France Region, Brest University Hospital, Grand Frais, and the Château de Versailles. Alongside storage it sells Leviia Next, a Nextcloud-based collaboration suite, and a partner program for MSPs and integrators who resell capacity from a shared console. None of that changes the storage calculus, but it tells you the company is a going concern with a channel, not a hobby project.

Pricing: what you really pay

The price is one number: €9.99 per TB per month excluding VAT, flat, with volume discounts above the entry tier. There are no egress charges, no API request charges, and no early-deletion fees — the three line items that make hyperscaler storage bills unpredictable. The catch sits in the ordering terms: the minimum order is 10 TB of storage, which puts the entry commitment at €99.90 per month excluding VAT, and direct subscriptions are sold on an annual basis. A 15-day free trial exists with no credit card required and up to 1 TB of data to play with, but the trial project is still bound by the 10 TB floor when you convert.

That structure makes the target buyer obvious. If you are pushing 10 TB or more of backup archives into offsite storage, the economics are clean and the budgeting is trivial. If you want to park 200 GB, this is not your service — the minimum order alone would make a pay-as-you-go competitor cheaper, and there is no self-serve small tier to fall back on. Leviia's own comparison charts position it against AWS S3 at roughly €22 per TB per month with egress near €85 per TB, plus OVHcloud, Scaleway, and Wasabi; the claim of being meaningfully cheaper than hyperscaler list pricing holds, though the sovereign European alternatives it lists alongside itself are the real comparison set.

One warning about reading Leviia's own material: pricing figures vary across its pages. The Storag3 pages consistently say €9.99 per TB per month, but other parts of the site have quoted lower per-terabyte numbers in dollars, and the site's built-in calculator uses published competitor tier rates with its own annual-plan price. Budget on the €9.99 contract figure and confirm anything else in writing before signing.

Performance & infrastructure

The architecture is erasure-coded across three data centers in France, with storage zones in Lyon and Marseille selected when you create an account. Data is not mirrored as whole copies but split and coded across sites, which is why the vendor claims durability of 99.999999999% — eleven nines — and states that data remains accessible even if one site goes dark. As with any durability claim, that is a design figure rather than a guarantee we can independently verify, but the multi-site erasure approach is the right one for a backup target.

The S3 compatibility story is the strongest technical point. The API works with the tools people actually use for offsite backup: Veeam, Acronis, Commvault, Rubrik, Atempo, Bacula, NAKIVO, HYCU, MSP360, rclone, and Synology and QNAP NAS appliances. Object Lock (S3 Object Lock, WORM semantics) provides immutability against ransomware, versioning is supported, lifecycle rules can clean up by bucket or folder, and IAM models map closely enough to AWS patterns for fine-grained permission control. Encryption is HTTPS in transit with AES-256 server-side, plus support for client-side encryption if you would rather hold the keys yourself. An anti-DDoS shield fronts access.

For the primary use case — immutable offsite copies of Veeam or Commvault backups — this is a well-matched feature set. Practitioners have published working walkthroughs of wiring Veeam Backup & Replication to a Storag3 bucket with object locking, and the dashboard supports bucket policies, quotas, and monitoring at a level that will not embarrass a managed-service provider running multiple customers from one console.

What the platform does not offer is the rest of the object-storage universe: no storage classes, no CDN integration, no global edge presence, and no per-region replication outside France. The French-only footprint is the product's identity and its ceiling at the same time. Latency from outside France will be whatever the internet gives you, and there is no option to pin a copy in another jurisdiction for redundancy.

Where it falls short

The commitment terms are the first real constraint: 10 TB minimum and an annual subscription. That rules out casual use, small projects, and anyone who wants to scale storage down. Pay-as-you-go competitors are friendlier for bursty or uncertain volumes, even at higher per-terabyte rates.

There is no published uptime SLA that we could find. The certifications and the multi-site design are reassuring, and the durability figure is prominent, but durability is not availability: nothing contractual pins the percentage of time the API answers. For a backup target that is often acceptable — restores are occasional and can wait — but for anything serving production reads it is a gap we would want closed in the contract.

The vendor is small and young. Founded in the late 2010s, first storage product in 2023, infrastructure migrated in 2024 — there is limited long-term track record, and the customer counts are self-reported. The certifications (ISO 27001, HDS) are real external scrutiny and count for more than marketing, but a 10 TB annual contract with a young company deserves a look at its financial footing and an exit plan (S3 compatibility makes migration out reasonably painless, which helps).

Finally, the sovereignty pitch needs precision. Data lives in France in Free Pro data centers, the legal entity is French, and the software stack is described as fully open source with no US components — a strong position versus US-owned providers. But sovereignty is a legal analysis as much as a technical one, and buyers in regulated sectors should verify the certification scope covers their workload type rather than assume the marketing covers their case.

Who should pick this

We would pick Leviia Storag3 for French and European organizations with 10 TB or more of backup, archive, or compliance data that must stay on French territory under French law — hospitals, local government, mid-size enterprises with Veeam or Commvault estates, and MSPs who want a sovereign target for customer backups with immutable object locking. If your biggest fear in a storage bill is the egress line, the flat pricing alone justifies the shortlist.

We would not pick it for small volumes, for pay-as-you-go experimentation, for workloads needing global distribution or CDN-adjacent performance, or for teams that cannot commit to a year. In those cases the per-terabyte price is irrelevant because the minimum order dominates. For sovereign object storage in France it is one of the sharper options in our cloud-object-storage category, and the flat-rate simplicity is genuinely refreshing.

Key takeaways

• French sovereign, S3-compatible object storage (Storag3): €9.99/TB/month flat, no egress, API-request, or deletion fees
• Entry barrier is real: 10 TB minimum (€99.90/month excl VAT) and an annual commitment; 15-day trial with up to 1 TB
• Erasure-coded across three Free Pro data centers in France (Lyon and Marseille zones) since 2024; ISO 27001 and HDS certified
• Strong backup-tool integration (Veeam, Commvault, Acronis, Synology/QNAP) with S3 Object Lock immutability and versioning
• No published uptime SLA and a young vendor — durability is designed (11 nines claimed), availability is not contracted
• Our pick for French organizations shipping 10 TB+ of backups to sovereign storage; wrong fit for small or bursty volumes
