Needs review
Shortlist when you want a Ceph S3 bucket next to Contabo VPS or VDS, can use path-style endpoints, and can live without S3 logging. Skip when you need Amazon-complete S3, a first-party custom TLS hostname, company-wide ISO 27001 or SOC 2, or a store with no US parent and no US region. Consider Hetzner Object Storage or OVHcloud Object Storage instead.

Ceph S3 API with path-style buckets
Contabo states the store is Ceph-based and largely S3 compatible, not fully equivalent to Amazon S3. Logging is not supported. Official tool notes require Contabo S3 URLs, path-style buckets, and access_key/secret_key mapped to aws_access_key_id/aws_secret_access_key.
EU, US, and Singapore S3 endpoints
Documented base URLs are eu2.contabostorage.com (European Union), usc1.contabostorage.com (United States), and sin1.contabostorage.com (Singapore). The management API allows one object-storage purchase per location. All locations on an account share the same S3 credentials.
Bucket versioning and Object Lock
Versioning is enabled per bucket via s3api put-bucket-versioning on the regional endpoint. Suspending versioning stops new versions but does not delete old ones. Object Lock can be turned on at bucket creation (example uses GOVERNANCE mode) so objects cannot be overwritten or deleted for a retention period.
Capacity auto-scale via management API
The Contabo API (not the S3 API) orders, upgrades, cancels, and auto-scales purchased space up to a monthly size limit. Usage statistics are exposed there. The open-source cntb CLI (GPL-3.0) wraps the same management API. S3 keys come from the User Management API or the Object Storage panel.
Published client list and hard limits
Documented working tools include cntb, aws cli, rclone, Cyberduck, goofys, s3fs-fuse, s3cmd, WinSCP, Cloudberry Explorer, BucketAnywhere, Virtualmin, Velero, and Plesk. FileZilla Pro is listed as incompatible. Defaults include 5 TB max object size, 100 buckets, 3 million objects (increasable on request), 250 requests per second, and 10 MByte/s default bandwidth.
MaxIOPS Block Storage
UpCloud's proprietary storage technology delivers up to 100,000 IOPS on read/write operations, verified in benchmarks like those from Cloud Spectator. This enables databases and high-traffic apps to run smoothly without bottlenecks. Storage attaches directly to servers, with snapshots for quick backups. Users benefit from consistent performance across all plans, unlike tiered systems elsewhere.
Global Data Centers and Networking
Choose from 13 locations: eight in Europe (Helsinki, Amsterdam, Frankfurt, London, Madrid, Warsaw, Stockholm, Copenhagen), plus Chicago, New York, San Jose, Singapore, and Sydney. Networking includes free load balancers, VPN gateways, and NAT for private connectivity. No charges apply for ingress or egress traffic, reducing bills for data-heavy workloads.
Managed Services and Essentials Package
Deploy managed PostgreSQL, MySQL, Valkey, or OpenSearch databases with automated scaling and updates. Managed Kubernetes control planes handle etcd and upgrades. The free UpCloud Essentials package bundles daily backups, floating IPs, and basic firewalls at no added cost. API access supports automation for CI/CD pipelines.
| Assurance & compliance | Contabo Object Storage | UpCloud |
|---|---|---|
| Independent security / no-logs audit | Not found Searched About, help, and product docs. No public independent audit PDF for Object Storage. | Nicht angegeben |
| ISO 27001 | Partial Some Contabo location marketing pages list colocation-facility ISO 27001 (for example Singapore). No company-wide Contabo ISO 27001 certificate found. | Nicht angegeben |
| SOC 2 / SOC 3 | Not found No Contabo-issued SOC 2 or SOC 3 report found. Facility-level SOC marks on some non-EU location pages are not treated as a Contabo attestation. | Nicht angegeben |
| GDPR / EU data protection | Vendor claimed EU legal entity; DPA available in the Customer Control Panel and listed as covering Object Storage. EU region is optional, not exclusive. | Nicht angegeben |
| US CLOUD Act exposure (indicative) | Partial Contabo GmbH is German, but KKR (US) has been the majority investor since June 2022 and Contabo sells a US object-storage region. Not legal advice. | Nicht angegeben |
| Data processing agreement (B2B) | Vendor claimed Customer Control Panel wizard. Object Storage is an explicit covered service. Review the generated PDF. | Nicht angegeben |
| EU AI Act | Not applicable Object storage IaaS, not an AI system. | Nicht angegeben |
| Considerations & known limitations | Contabo Object Storage | UpCloud |
|---|---|---|
| US private-equity majority owner | High Oakley Capital announced in June 2022 that KKR would be majority investor, with Oakley Fund V retaining a minority stake. Treat CLOUD Act exposure as high at the ownership layer even when objects sit on eu2.contabostorage.com. | Nicht angegeben |
| Optional United States object region | Medium usc1.contabostorage.com is a first-party SKU. Shared credentials across locations make it easy to point a client at the US endpoint by mistake. Pin the EU URL if residency is a hard requirement. | Nicht angegeben |
| Partial S3 compatibility | Medium Contabo states the Ceph API is not fully compatible with AWS S3. Logging is unsupported. Path-style addressing is required. FileZilla Pro does not work. Test SDK features before migrating production. | Nicht angegeben |
| Default request and bandwidth caps | Medium Published defaults include 250 API requests per second, 10 MByte/s bandwidth, 100 buckets, and 3 million objects. Auto-scale increases purchased terabytes, not those caps. | Nicht angegeben |
| No public company-wide audit | Medium No independent Object Storage audit, Contabo-issued ISO 27001, or SOC 2 report was found. Facility ISO/SOC marks on some location pages are not a substitute. | Nicht angegeben |
| No first-party custom TLS hostname | Low HTTPS-only S3 endpoints reject a simple CNAME. Public websites need a customer-operated reverse proxy. Public-to-private ACL changes may remain cached for up to one hour. | Nicht angegeben |
When: You want a German hoster's object store with an EU-concentrated footprint and no US majority PE owner
Consider: Hetzner Object Storage
Contabo's own comparison places Hetzner object storage in European data centers and notes a thinner APAC story.
When: You need a broader EU compliance portfolio (ISO 27001, SecNumCloud) more than a simple capacity bill
Consider: OVHcloud Object Storage
Billing and product surface are more complex than Contabo's single-account IaaS stack.
When: You need managed Kubernetes or managed Postgres next to S3, not just raw buckets
Consider: Scaleway Object Storage
France-first footprint. Contabo does not sell first-party managed databases or Kubernetes.
When: You need Amazon-complete S3 (logging, IAM, global regions) and will accept a US cloud
Consider: Amazon S3
Use Contabo only after you have tested the Ceph compatibility gaps against your SDK.
