S3 Object Storage. S3 storage in Europe. No egress traps, no US Cloud Act.
Many applications, backup tools and data platforms speak S3. That is a good thing. But anyone running their S3 storage with an American hyperscaler pays not just for storage but also for egress traffic, and accepts that their data falls under US jurisdiction. Our S3 storage is fully S3-API-compatible, runs in German and European data centers, costs €0.009 per GB per month and makes no compromises on GDPR compliance or vendor lock-in.
What S3 storage is and why the protocol matters so much.
S3 stands for Simple Storage Service and was originally an AWS product. What has remained is this: the S3 API is today the de-facto standard for object storage. Backup software like Veeam, Restic and Bacula speaks S3. Data platforms like MinIO, Ceph and Rclone speak S3. Container platforms, application frameworks and CI/CD pipelines speak S3.
That means anyone who builds on S3 storage can build their entire data stack on top of it without locking themselves into a single provider. A different platform, a different region, a different provider. Everything works through the same API.
Our S3 storage is fully compatible with the S3 API, runs on our own infrastructure in German and European data centers and works as a direct target for backup software, as a storage backend for applications, as an intermediate layer in the archiving lifecycle and as a data storage layer for AI and machine learning pipelines.
What you gain when your S3 storage sits in Europe.
Scalable without downtime
From a few gigabytes to several petabytes. No upgrade process, no downtime, no capacity planning that needs to be completed in advance. Your S3 storage grows with your needs.
GDPR-compliant without compromise
All data sits in German or European data centers and does not leave the EU. No US Cloud Act risk, no data transfer to third countries, no compliance trade-offs. weSystems is certified to ISO 27001:2022.
No expensive egress fees
Large cloud providers charge significant fees for outbound data traffic. With us, traffic is transparently and affordably priced, without hidden cost traps that make your monthly bill unpredictable.
Fully S3-compatible
The same API as AWS S3, but without AWS. Every piece of software, every tool and every platform that speaks S3 works with our S3 storage without modification. No migration effort, no code rewrite.
For backups, applications and lifecycle
As an S3 storage target for Veeam, Restic or Proxmox Backup Server. As a storage backend for web applications. As an intermediate layer before the archive. Our S3 storage fits many roles within the same data ecosystem.
No vendor lock-in
Because S3 is an open standard, you can move your data to another S3-compatible provider at any time. No proprietary formats, no dependency on a single vendor.
What S3 storage is used for every day.
Backup target for Veeam, Restic und Proxmox
S3 is the preferred backup target of modern backup solutions. Our S3 storage receives backups directly, without an intermediary layer, with consistent performance and transparent billing.
Storage backend for web applications
Images, videos, documents, user uploads. Everything an application needs to store that does not belong in the database lands sensibly in S3 storage, via S3 API directly from the application.
Data lake for analytics and AI
Raw data from various sources, training data for AI models, logs and events. S3 storage as a central data lake that analytics platforms, Spark jobs or ML pipelines access directly.
Intermediate layer in the archiving lifecycle
Active data sits on Performance Storage. Older data moves into S3 storage as an intermediate layer. From there, Miria orchestrates the transfer to magnetic tape in the long-term archive. The entire lifecycle runs via S3 APIs.
Log aggregation and SIEM integration
Security logs, audit trails and system events land in S3 storage and are retrieved directly by SIEM systems like Graylog or Splunk. Cost-efficient, scalable and audit-proof.
Media hosting and content delivery
Static assets, media files and publicly accessible content can be served directly via S3, without dedicated media servers and without storage limits.
S3 object storage prices
Transparent pricing with no hidden charges. Usage-based, no minimum contract term and no setup fee.

Good advice means naming the alternatives too.
That is something not many providers say out loud. But it is part of how we work. Anyone using our S3 storage is not locked in. The S3 API is an open standard. Your data can be migrated to another provider at any time using the same tools and the same scripts, without code changes and without proprietary formats.
What sets us apart regardless: we operate the infrastructure ourselves, in our own data centers in Germany and the Netherlands. No reselling, no dependency on a third-party backend. What you book sits on our hardware, operated by our team, with a contact who knows you.
And because S3 storage rarely stands alone, we think about the entire data path from the start. As a backup target, as part of an automated storage lifecycle or as a data storage layer for applications. Talk to us. We will look at your situation together and tell you honestly what genuinely makes sense.

Frequently asked questions
What is S3 storage?
S3 storage is a scalable storage solution that stores data as objects and makes it accessible via the S3 API (Simple Storage Service API). The S3 API is today the de-facto standard for object storage and is supported by virtually all modern backup, application and data platforms. weSystems provides S3 storage in German and European data centers, GDPR-compliant and without vendor lock-in.
What is the difference between S3 storage and file storage?
File storage organises data in hierarchical directories. S3 storage stores data as flat objects with metadata, without a directory structure. That makes S3 storage significantly more scalable, easier to replicate and ideal for unstructured data such as backups, media, logs or AI training data.
Is the S3 storage fully S3-API-compatible?
Yes. Our S3 storage implements the S3 API completely. Every piece of software, every tool and every platform that supports S3 works without modification, including Veeam, Restic, Proxmox Backup Server, Rclone, MinIO clients and many more.
Which use cases are suitable for S3 storage?
Backup target for Veeam, Restic and other backup tools, storage backend for web applications and user uploads, data lake for analytics and AI pipelines, intermediate layer in the archiving lifecycle, log aggregation for SIEM systems and media hosting.
Is S3 storage GDPR-compliant?
Yes. All data is stored in German or European data centers and does not leave the EU. weSystems is certified to ISO 27001:2022. A data processing agreement is available on request.
How secure is S3 storage at weSystems?
Data is transmitted encrypted and can be stored encrypted. Role-based access controls, ACLs and S3 bucket policies protect against unauthorised access. The infrastructure runs in ISO-certified data centers with redundant power supply and network connectivity.
Is there vendor lock-in with S3 storage?
No. The S3 API is an open standard. Your data can be migrated to another S3-compatible provider at any time using standard tools like Rclone, without code changes and without proprietary formats.
How is S3 storage billed?
Billing is usage-based per GB per month. S3 storage costs €0.009 per GB/month. Egress traffic is billed separately. No setup fee, no minimum contract term.
Can S3 storage be part of an automated storage lifecycle?
Yes. Our S3 storage is ideal as an intermediate layer between Performance Storage and long-term archive. With Miria by Atempo we orchestrate the fully automated transfer from S3 to magnetic tape according to defined lifecycle rules, also at petabyte scale.
