Storadera

What Is Storadera?

One price does most of the talking: EUR 7.95 per terabyte per month, excluding VAT, with no separate charge for API requests and free egress within a fair-use allowance equal to whatever you store. That single flat rate covers three EU data centres — Tallinn, Falkenstein, and Helsinki — and a service that reportedly holds roughly a hundred customers, among them the Estonian government and Telia. Behind it sits a team of fewer than ten people generating a little under EUR 1 million a year, profitable and bootstrapped since the service went live in 2021.

Storadera was founded in Tallinn in 2019 by CEO Tommi Kannisto and built around a deliberately unfashionable idea: sell S3-compatible object storage as a commodity, at one honest price, hosted entirely inside the European Union. Where AWS S3 layers storage, request, and egress meters into a bill that is genuinely hard to predict, Storadera bills for stored volume and stops there. The company runs its own storage software on colocated hardware at Greenergy in Estonia and Hetzner in Germany and Finland.

Storadera's pitch lands cleanly against the incumbents it targets — AWS S3, Backblaze B2, Wasabi, and DigitalOcean Spaces. What complicates the story is that Storadera's headline price has moved. It launched at EUR 6 per TB, rose to EUR 7 in November 2025, and now sits at EUR 7.95. The "cheapest S3 in the EU" framing that fit in 2022 needs a caveat in 2026.

Key Features

What do you actually get for EUR 7.95 per TB?

Billing simplicity is the feature. For EUR 7.95 per TB per month you get object storage with no API-request fees, no minimum storage duration, and no early-deletion penalty. That's a contrast with Wasabi, which enforces a 90-day minimum retention and a 1 TB monthly floor. Egress is free within a fair-use limit set equal to your stored volume, so a 10 TB account can download up to 10 TB a month at no cost before enterprise terms apply.

That fair-use cap is worth stating plainly, because the marketing shorthand of "no egress fees" oversells it slightly. Storadera is not offering unlimited free bandwidth; it is offering a 1:1 egress-to-storage ratio that suits backup and archival workloads far better than high-traffic content delivery. A recent change also added a EUR 1 minimum monthly invoice, waived when you store nothing.

Which regions and data centres does Storadera use?

Three regions, all inside the EU: Estonia (Tallinn), Germany (Falkenstein), and Finland (Helsinki). Storadera does not own data centres — it colocates in Greenergy's EN 50600-rated Tallinn facility and in Hetzner sites in Germany and Finland, running its own storage stack on top. Every byte therefore stays under EU jurisdiction, which is the whole point of the service.

Three regions is also the clearest limitation. AWS spans dozens of regions across continents, Wasabi and Backblaze offer US and multiple international options, and DigitalOcean Spaces covers several global datacentres. A customer needing storage physically close to users in Asia or the Americas is not Storadera's target, and never will be.

How does the S3 API and tool compatibility hold up?

Compatibility is where a small provider either works or wastes your afternoon, and Storadera works. The API is S3-compatible, so the standard toolchain connects with nothing more than an endpoint and a pair of credentials: rclone, the AWS CLI, s3cmd, and Cyberduck all talk to it directly. That also makes migration in or out a copy command rather than a project.

Backup software is the real ecosystem here. Veeam Backup & Replication, Synology Hyper Backup, Acronis Cyber Protect, MSP360, Duplicati, and Comet all list Storadera as a target. The CEO has said roughly half of stored data arrives via Veeam and half via resellers. What you will not find is a broad application marketplace, native CDN integration, or documented lifecycle-policy automation — the feature surface stops at solid, standards-compliant storage.

What protects backups from deletion and ransomware?

Immutability does the heavy lifting. Storadera supports object lock in write-once-read-many (WORM) mode, so an object written with a retention period cannot be modified or deleted until that period expires — even by an attacker holding valid credentials. Paired with object versioning, this delivers the ransomware-resistant backup target that Veeam and similar tools increasingly demand.

Encryption is applied in transit and at rest, though Storadera publishes little technical detail about algorithms or key management, so security teams that need specifics will have to ask. For most backup and archival use cases, immutability plus versioning plus EU residency covers the requirements that actually appear in procurement checklists.

Pricing

Simplicity is the entire pricing proposition, and it mostly delivers. Storage costs EUR 7.95 per TB per month excluding VAT, billed pay-as-you-go with a EUR 1 minimum invoice, no request fees, no retention minimum, and free egress up to your stored volume. A 30-day trial provides 50 GB free with no credit card, using the same API as a paid account. Enterprise customers negotiate volume pricing and larger download allowances separately.

Set against the field, the number is competitive rather than dominant. Backblaze B2 runs about $6 per TB with three times your stored volume in free monthly egress. Wasabi rose to $7.99 per TB in July 2026 but carries retention minimums Storadera avoids. AWS S3 Standard sits near $23 per TB before you add egress and request charges. Storadera at roughly $8.60 equivalent per TB now lands close to Wasabi and above Backblaze — cheap next to AWS, no longer the outright price leader among EU-friendly options.

The honest read: buy Storadera for predictable EU-hosted billing and no metering surprises, not because it is categorically the cheapest storage you can find. For backup workloads where egress stays near stored volume, the all-in cost is easy to forecast, which is worth real money to teams burned by AWS egress bills.

EU Compliance & Privacy

Data residency is Storadera's strongest compliance argument. Every byte lives in EU data centres in Estonia, Germany, and Finland, and Storadera OU is an independent Estonian company. There is no US parent that could be compelled to disclose data under the CLOUD Act. For an EU organisation whose main worry is where data physically sits and who can legally reach it, that structure is about as clean as it gets.

The certification picture needs care, because it is easy to overstate. Those ISO 27001 and EN 50600 certifications frequently cited around Storadera belong to the underlying data-centre operators — Greenergy and Hetzner — not to Storadera itself. Storadera does not hold an independent ISO 27001 or SOC 2 attestation, and no explicit GDPR data processing agreement surfaced during research. Buyers in regulated sectors should request that documentation directly rather than assume a vendor-level certificate exists.

For teams whose bar is EU jurisdiction and physical residency, Storadera clears it comfortably. Teams whose bar is an independent audit report they can file with compliance should, today, ask and verify.

Who It's Best For

EU teams running backup and archival workloads who want a predictable bill. Veeam, Synology, Acronis, and MSP360 users can repoint an existing job at Storadera and know their monthly cost in advance.

Organisations with hard EU data-residency requirements and no appetite for US ownership. An independent Estonian company storing data only in the EU is a strong sovereignty story, CLOUD Act included.

Cost-sensitive shops fleeing AWS egress bills whose download volume stays near their stored volume. For that profile, the fair-use egress model turns an unpredictable AWS line item into a flat number.

Storadera is a poor fit for high-egress content delivery, where the 1:1 fair-use cap bites and a CDN-backed provider like Backblaze plus Cloudflare fits better. Global applications needing regions outside Europe, and buyers who require a vendor-level ISO 27001 certificate before onboarding, should also look elsewhere.

The Verdict

Storadera is a clean, honest, EU-hosted object store that does one thing well and refuses to complicate it. Flat per-TB pricing with no request fees, immutability for ransomware-resistant backups, broad backup-tool compatibility, and genuine Estonian independence make it a credible AWS S3 alternative for European backup and archival workloads. The limits are real and worth weighing: three regions only and a fair-use egress cap rather than truly free bandwidth. There's also no vendor-level ISO 27001 or SOC 2 certification, a very small team, and a price that has crept up twice since launch. For EU teams that value predictable billing and data residency over global reach and audit certificates, Storadera earns its place on the shortlist.

Frequently Asked Questions

Is Storadera GDPR compliant and where is my data stored?

Storadera stores data exclusively in EU data centres — in Tallinn (Estonia), Falkenstein (Germany), and Helsinki (Finland). As an independent Estonian company, Storadera OU has no US parent and no CLOUD Act exposure. The underlying facilities (Greenergy in Tallinn, Hetzner in Germany and Finland) hold ISO 27001 and EN 50600 certifications. Note that Storadera itself does not hold an independent ISO 27001 or SOC 2 certification, so buyers who need a vendor-level attestation should request documentation directly.

How does Storadera compare to AWS S3?

Storadera is far cheaper and simpler, but far narrower. It costs a flat EUR 7.95 per TB/month with no API-request fees and no egress charges within a fair-use allowance, against AWS S3 Standard at roughly $23 per TB plus separate egress and request fees. AWS offers dozens of global regions and a huge feature surface — Glacier tiers, Object Lambda, lifecycle automation, a vast ecosystem — that Storadera does not attempt to match. For EU-hosted backups and archival where predictable pricing matters more than breadth, Storadera wins on cost and data residency; for a full cloud platform, AWS remains in a different category.

Is there a free tier or trial, and what does storage actually cost?

There is no permanent free tier, but a 30-day trial gives you 50 GB free with no credit card and the full feature set. After that, storage is a flat EUR 7.95 per TB per month excluding VAT, billed pay-as-you-go with a EUR 1 minimum invoice. There are no API-request fees, no minimum storage duration, and no early-deletion penalty. Egress is free within a fair-use allowance equal to your stored volume, above which enterprise terms apply.

Can I migrate from AWS S3 or another S3 provider to Storadera?

Yes. Storadera exposes a standard S3-compatible API, so tools such as rclone, AWS CLI, s3cmd, and Cyberduck can copy buckets across with only an endpoint and credential change. Backup software including Veeam, Synology Hyper Backup, Acronis, and MSP360 lists Storadera as a target, so many teams simply repoint an existing backup job. There is no proprietary lock-in, which also makes leaving straightforward.

Does Storadera protect backups against ransomware?

Yes. Storadera supports object immutability (write-once-read-many, or WORM) alongside object versioning. A backup written with a retention lock cannot be altered or deleted before its retention period expires, even by an attacker with valid credentials. Combined with versioning, this gives ransomware-resistant backups that meet a common requirement for Veeam and other immutable-backup workflows.
