Hetzner Object Storage

Germany· Cloud Computing

Needs review

Shortlist when you want S3-compatible buckets in Falkenstein, Nuremberg, or Helsinki under Hetzner Online GmbH, especially if you already run Hetzner compute. Skip when you need AWS-parity features, flash tiers, a CDN, or default KMS at-rest encryption. Prefer Amazon S3 for full feature depth; prefer Scaleway or OVHcloud if you want another European S3 SKU without a Hetzner compute relationship.

Leafcloud Object Storage

Netherlands· Cloud Computing

Needs review

Shortlist Leafcloud Object Storage when you want an S3-compatible Ceph bucket in Amsterdam under Leafcloud B.V., with a public ISO 27001 certificate and a downloadable DPA. Skip when you need object versioning, multi-region replication, or AWS-parity S3 features. Consider Cyso Cloud for Dutch OpenStack storage with versioning and a Frankfurt option, or OVHcloud / Scaleway for a wider EU region map.

Hetzner Object Storage

S3 API with FSN1, NBG1, and HEL1 endpoints
Amazon S3 compatible API using AWS Signature Version 4. Location endpoints are fsn1.your-objectstorage.com, nbg1.your-objectstorage.com, and hel1.your-objectstorage.com. AWS CLI and common SDKs work when pointed at the Hetzner endpoint. Console covers bucket create and credentials; almost all object operations go through the S3 API.
Single-location EU bucket residency on Ceph
A bucket is stored entirely in the location you pick (Falkenstein, Nuremberg, or Helsinki), in one data center. Docs describe a Ceph cluster with erasure coding that can keep data intact if up to three storage servers fail. There is no US or Singapore object-storage region and no built-in cross-location replication.
Object lock, versioning, and lifecycle expiry
Object Lock can be enabled at bucket create (legal hold and retention). Versioning and lifecycle rules are documented, including NoncurrentDays expiry. Pre-signed URLs give time-limited access. Object lock cannot be turned on later for a bucket created without it.
SSE-C encryption (no default at-rest, no SSE-KMS)
There is no default data-at-rest encryption. Optional SSE-C encrypts object bytes with a customer-provided key that Hetzner says it discards after use. Metadata is not encrypted. Losing the key means losing access. SSE-C object copy is listed as unsupported.
Project-wide keys, documented S3 gaps, and hard limits
By default each key pair can read and write every bucket in the same project unless you add bucket policies or split projects. Account limits include 100 buckets, 100 TB and 50 million objects per bucket, 5 TB max object, 5 GB per single PUT, 750 requests per second per bucket, and 10 Gbit/s per bucket. Notifications, website hosting, inventory, replication, and custom domains are not supported.

Leafcloud Object Storage

S3 API at leafcloud.store (europe-nl-ams1)
Path-style S3 endpoint https://leafcloud.store, region europe-nl-ams1. Works with AWS CLI, boto3, rclone, Cyberduck, MinIO mc, and other S3 SDKs. Documented features include public or private containers, bucket policies and ACLs, multipart uploads, and presigned URLs. Max object size is 5 TB via multipart. Authentication uses OpenStack EC2 credentials (openstack ec2 credentials create), not the dashboard password.
OpenStack Swift and Horizon dashboard
The same store is reachable as OpenStack object storage (Swift). Create and browse containers at create.leaf.cloud under Object Store. Native CLI uses project-scoped OpenStack auth (openstack container create / object create). Container names must be unique across all Leafcloud users. Docs say there is a limit on how many containers you can create (the exact quota is not published).
Ceph cluster with 3x replication in Amsterdam
The product page describes a Ceph backend (Apache 2.0 software) with triple replication across separate physical nodes in Amsterdam. Persistent objects sit at the Core facility. Compute Leaf sites are a different path and are not where object data is stored, according to the security pages. This is a single-region store, not a multi-region S3 deployment.
SSE-C plus TLS in transit
Official docs show S3 server-side encryption with customer-provided keys (SSE-C, AES256). Leafcloud uses the key on each request and does not store it. Lose the key and you cannot read the object. The product table also lists encryption at rest and TLS in transit as supported. DPA language is TLS 1.2+. LUKS-by-default messaging on the security pages refers to block volumes, not this object API.
Terraform state, Velero, and Nextcloud recipes
Leafcloud publishes working recipes for Terraform’s S3 backend (path-style, skip checksum/region checks, endpoint leafcloud.store), Velero Kubernetes backups (s3ForcePathStyle plus s3Url), and Nextcloud primary objectstore pointing at leafcloud.store:443. Useful if you already run those tools. Object versioning is not available, so state and backup designs must version keys themselves or copy out.

Assurance & compliance: Hetzner Object Storage vs Leafcloud Object Storage
Assurance & compliance	Hetzner Object Storage	Leafcloud Object Storage
Independent security / no-logs audit	Not applicable IaaS object store, not a no-logs VPN. Company publishes ISO 27001, BSI C5 Type 2, and annual TOM review instead.	Not found No public independent no-logs or object-store-specific audit PDF found. SOC 2 Type II is a separate row and is under NDA.
ISO 27001	Verified Public ISO/IEC 27001:2022 certificate (SOCOTEC) for the ISMS covering Nuremberg, Falkenstein, and Helsinki parks. Confirm attested scope includes this SKU with your auditor.	Verified Public ProCertify certificate 10112025.1 for LeafCloud B.V.: ISO/IEC 27001:2022 + Amd1:2024. Scope: information security for cloud services, infrastructure, and supporting processes. Valid 10 Nov 2025 to 10 Nov 2028. SoA v3.1 dated 5 Aug 2025. Read from the vendor-hosted PDF; not re-checked on an external accreditation database.
SOC 2 / SOC 3	Not found Hetzner states it focuses on ISO 27001 rather than SOC 2.	On request / NDA Vendor and DPA claim SOC 2 Type II (security, availability, confidentiality). Compliance page: request access by email. Report not reviewed for this draft.
GDPR / EU data protection	Vendor claimed German entity; public privacy policy, Art. 28 DPA, TOMs, subprocessor list. Customer remains controller for data stored in buckets.	Vendor claimed Dutch B.V.; public DPA under Dutch law; vendor states Amsterdam-only processing and no third-country transfers unless instructed. Confirm roles (controller/processor) for your workload.
US CLOUD Act exposure (indicative)	Partial EU entity, no known US parent, Object Storage has no US region and no US-group storage backend. Group still includes Hetzner US LLC for other products. Not legal advice.	Partial EuropeanStack assessment: EU entity, no known US parent, DPA says no core subprocessors and NL-only processing. Partial because ownership was not independently verified and terms/privacy still allow partner data centres plus unnamed account-data suppliers. Not legal advice.
Data processing agreement (B2B)	Vendor claimed Standard DPA accept-in-console; sample PDF published; no custom wet-ink DPAs per vendor docs.	Vendor claimed Standard DPA dated January 2026 is public and states it applies automatically (no signature). Custom DPA on request. Governing law: Netherlands; courts of Amsterdam.
EU AI Act	Not applicable Object storage infrastructure, not an AI system product.	Not applicable Object storage / IaaS SKU, not an AI system product.
BSI C5 (cloud)	Verified Vendor publishes a BSI C5 Type 2 attestation PDF for cloud services. Confirm whether Object Storage is inside the attested cloud-service scope.	Non indiqué

Considerations & known limitations: Hetzner Object Storage vs Leafcloud Object Storage
Considerations & known limitations	Hetzner Object Storage	Leafcloud Object Storage
Partial S3 compatibility	Medium Supported-actions list omits website hosting, notifications, inventory, replication, custom domains, SSE-KMS, and more. CopyObject may fail even in one location. Apps that assume full AWS S3 will break.	Non indiqué
HDD tier, not a CDN	Medium Standard HDD only, no archive or flash classes. Hetzner says it is a poor fit for high-frequency small objects, low-latency apps, and large-scale public HTTP. Plan a CDN or different storage for those cases.	Non indiqué
No default at-rest encryption	Medium Objects are not encrypted at rest unless you use SSE-C and keep the key. Lost keys are unrecoverable. SSE-C copy is unsupported.	Non indiqué
Single data center, no built-in replication	Medium A bucket lives in one DC. There is no first-party cross-location replication. You must build DR yourself if one park outage is unacceptable.	Non indiqué
Shared-cluster load and 503s	Medium Vendor docs describe cluster growth, bucket migrations, and temporary concurrency or upload limits (including 503 in Nuremberg under load). Shared tenancy can affect latency.	Non indiqué
Group US and Singapore entities	Low This SKU is EU-only, but Hetzner Online GmbH has US and Singapore subsidiaries for other Cloud locations. Zero-US-footprint procurement may still reject the vendor.	Non indiqué
Object versioning disabled	Non indiqué	High The product table states versioning is not enabled. Overwrites and deletes are not recoverable via S3 versions. Unsafe as a sole Terraform-state or backup target unless you version keys yourself or replicate out.
Amsterdam-only region	Non indiqué	Medium One S3 region (europe-nl-ams1). No documented cross-region replication. Multi-country DR or non-NL residency needs another provider.
Baseline SLA is a non-binding target	Non indiqué	Medium Terms target more than 99.9% monthly availability without credits on the baseline SLA. Customers must keep their own backups. Premium SLA only if agreed in writing.
Core facility operator not named	Non indiqué	Medium DPA says no core subprocessors. Terms mention partner data centres. Public pages do not name the Tier III Core operator. Request that name in contracting.
Incomplete S3 feature parity	Non indiqué	Low Custom domains are support-gated. Static hosting is basic. Do not assume lifecycle, object lock, or inventory APIs without a proof of concept.

Adéquation

Hetzner Object Storage

Best fit when

Teams already on Hetzner Cloud or dedicated servers that want an S3 endpoint under the same German contract
Backups, archives, dumps, and warm or cold blobs that fit write-once, read-many access
Workloads that can pin a bucket to Falkenstein, Nuremberg, or Helsinki and accept a single data center
Backup tools and apps that speak generic S3 (AWS CLI, rclone, MinIO client, Synology Hyper Backup)
Buyers who need object lock, versioning, or lifecycle expiry without US object-storage regions

Poor fit when

Apps that need Amazon S3 feature parity (events, website hosting, inventory, KMS, replication, storage classes)
CDN-style public delivery or high-frequency tiny-object / low-latency database use
Policies that require default provider-managed at-rest encryption (SSE-S3 or SSE-KMS)
Orgs that forbid any US subsidiary at group level even when this SKU stays in the EU
Buyers who need more than 100 buckets or first-party cross-location DR

Consider instead when

When: You need the full Amazon S3 feature set, storage classes, KMS, events, or global regions
Consider: Amazon S3
Accept US-group jurisdiction in exchange for catalog depth.
When: You want another European S3-compatible cloud without a Hetzner compute relationship
Consider: Scaleway or OVHcloud
Compare their object-storage regions, S3 gaps, and contract entities separately.
When: You are evaluating Hetzner VMs, bare metal, or the company as a whole
Consider: Hetzner
The company page covers IaaS and parks; this page is the bucket SKU only.
When: You want a smaller EU cloud with S3-oriented positioning
Consider: Cyso Cloud
Verify current regions and S3 compatibility on that product page.

Leafcloud Object Storage

Best fit when

Teams that need an S3-compatible endpoint and OpenStack Swift in one Dutch account
Amsterdam-only residency designs that can live without bucket versioning
Velero, Terraform state, or Nextcloud setups that already use path-style S3 clients
Buyers who want a public ISO 27001 PDF and a standard DPA before a sales call
Organisations that may later add Leafcloud VMs or GPUs in the same jurisdiction

Poor fit when

Workloads that require S3 versioning, object lock, or cross-region replication
Multi-region or in-country-outside-NL residency (this store is Amsterdam only)
Procurement that needs a named Core colocation operator and a full ancillary subprocessor register on day one
Consumer or free-tier only use (terms position Leafcloud as B2B)
Designs that assume AWS IAM, KMS, or inventory/analytics feature parity

Consider instead when

When: You need Dutch or German OpenStack object storage with versioning and more than one EU region
Consider: Cyso Cloud
Cyso documents AMS and FRA and lists versioning, lifecycle, and object lock on object storage.
When: You need many European locations and a larger IaaS catalogue than a single Amsterdam Ceph cluster
Consider: OVHcloud or Scaleway
Broader region maps; different APIs, SLAs, and ownership stories.
When: German locations and a large self-serve European hosting catalogue matter more than OpenStack Swift
Consider: Hetzner
Compare object storage vs Storage Box features and residency independently.
When: Swiss multi-zone IaaS with S3-compatible storage is the sovereignty filter
Consider: Exoscale
Different legal seat (Switzerland) and product mix.
When: You depend on versioning, replication, IAM, and KMS that only the hyperscaler S3 estate provides
Consider: Amazon S3 (or Google Cloud Storage)
Trade EU ownership for feature depth. Apply your own CLOUD Act analysis.

Open questions for due diligence

Hetzner Object Storage

Does your auditor accept Hetzner's park-level ISO 27001 and cloud C5 Type 2 for this object-storage SKU without a SKU-specific statement of applicability?
Can your application live with the documented S3 gaps (no events, website, KMS, replication, custom domain)?
Is a single data center per bucket acceptable, or do you need first-party multi-site replication?
Will you operate SSE-C key management yourself, or do you require provider-managed at-rest encryption?
Does group presence of Hetzner US LLC block you even if buckets stay in DE/FI?

Leafcloud Object Storage

What is the current registered office on the KvK extract (Science Park 400 vs Overhoeksplein 2)?
Who operates the Amsterdam Core / partner data centre, and is that party listed as a subprocessor for physical hosting?
Can Leafcloud provide a dated list of ancillary processors (billing, support, email) used for account data?
Is there a committed date or paid option to enable Ceph/S3 versioning?
What contractual availability, durability, and deletion timelines apply to object storage under a Premium SLA versus the baseline terms (14-day vs 90-day deletion language differs between T&Cs and DPA)?
