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.

Contabo Object Storage
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.
| Assurance & compliance | Aruba Cloud | Contabo Object Storage |
|---|---|---|
| Independent security / no-logs audit | Nicht angegeben | Not found Searched About, help, and product docs. No public independent audit PDF for Object Storage. |
| ISO 27001 | Nicht angegeben | Partial Some Contabo location marketing pages list colocation-facility ISO 27001 (for example Singapore). No company-wide Contabo ISO 27001 certificate found. |
| SOC 2 / SOC 3 | Nicht angegeben | 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. |
| GDPR / EU data protection | Nicht angegeben | Vendor claimed EU legal entity; DPA available in the Customer Control Panel and listed as covering Object Storage. EU region is optional, not exclusive. |
| US CLOUD Act exposure (indicative) | Nicht angegeben | 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. |
| Data processing agreement (B2B) | Nicht angegeben | Vendor claimed Customer Control Panel wizard. Object Storage is an explicit covered service. Review the generated PDF. |
| EU AI Act | Nicht angegeben | Not applicable Object storage IaaS, not an AI system. |
| Considerations & known limitations | Aruba Cloud | Contabo Object Storage |
|---|---|---|
| US private-equity majority owner | Nicht angegeben | 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. |
| Optional United States object region | Nicht angegeben | 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. |
| Partial S3 compatibility | Nicht angegeben | 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. |
| Default request and bandwidth caps | Nicht angegeben | 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. |
| No public company-wide audit | Nicht angegeben | 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. |
| No first-party custom TLS hostname | Nicht angegeben | 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. |

Contabo Object Storage
Best fit when
- Teams already on Contabo Cloud VPS or VDS that need a same-account backup or media bucket
- Workloads that speak standard S3 via rclone, aws cli, Velero, Plesk, or s3cmd and can use path-style URLs
- Buyers who want capacity-tier billing without per-gigabyte egress modelling
- Operators who can pin eu2.contabostorage.com and sign the in-panel DPA
- Buckets that need versioning or Object Lock but not S3 server access logging
Poor fit when
- Applications that require full Amazon S3 feature parity, especially server access logging or virtual-hosted bucket names
- Public websites that need a first-party custom hostname and TLS without a reverse proxy
- Procurement that requires company-wide ISO 27001 or SOC 2, or a vendor with no US private-equity majority owner
- Strict EU-only policies if anyone on the account might create a US or Singapore store
- High-QPS or multi-gigabit pipelines that will hit the documented 250 rps or 10 MByte/s defaults
Consider instead when
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.
Open questions for due diligence
Aruba Cloud
Nicht angegeben
Contabo Object Storage
- Is there a current company-wide ISO 27001 or SOC 2 for Contabo GmbH (not a colocation-facility mark)?
- Where is the public subprocessor list for Object Storage, backups, support tooling, and the Customer Control Panel?
- Does Contabo offer server-side encryption at rest and customer-managed keys for objects? Not documented on the pages reviewed.
- What is the Ceph replication factor / durability target for each object-storage region?
- The marketing URL https://contabo.com/en/object-storage/ returned Storage VPS content when fetched during research. Confirm the SKU is still sold and the product page has not been retired.
