What to check before you choose

• Egress. Storage is usually the small part of the bill. Downloads are the large part.
• Request fees. Small files and frequent reads can cost more than the storage.
• Features you depend on. Object lock, versioning and lifecycle rules aren't universal.
• Availability. OVHcloud states 99.9% for one zone and 99.99% for three. Ask others for theirs.
• Exit. S3 compatibility makes moving between providers much easier.

Frequently asked questions

What is the cheapest S3-compatible storage in Europe?

It depends on your traffic. For 1 TB with modest downloads, Hetzner at €6.49 a month includes both the storage and 1 TB of traffic. For heavy downloads, a provider with no egress fees can cost less overall.

Is there a European alternative to Amazon S3?

Yes. Hetzner, OVHcloud, Exoscale, IONOS and Impossible Cloud all offer S3-compatible storage in Europe.

Is storing data with a European provider enough for GDPR?

No. It helps with where data sits, but you still need a data processing agreement, access controls and a lawful basis. Your own processing stays your responsibility.
