Migrate to/from Scaleway Object Storage (EU, GDPR)

What is Scaleway Object Storage?

Scaleway Object Storage is the S3-compatible object-storage tier from Scaleway, the French cloud-infrastructure company that runs its own datacenters in Paris (FR-PAR), Amsterdam (NL-AMS), and Warsaw (PL-WAW). As an independent European hyperscaler, Scaleway operates entirely under EU jurisdiction with strict GDPR compliance — no US ownership, no CLOUD Act exposure, and ISO 27001 / SecNumCloud-aligned infrastructure trusted by French government agencies and regulated industries. Scaleway offers three storage classes: Standard Multi-AZ (replicated across multiple availability zones), Standard One Zone (single-AZ, cheaper), and Glacier (cold archive). New users get 750 GB free Multi-AZ storage for 90 days, with a 50 % public-beta discount on certain features through May 31, 2026.

Scaleway's appeal is jurisdiction more than price: Wasabi ($6.99/TB), B2 ($6/TB), and IDrive e2 ($4/TB) are cheaper on raw storage, but none operate exclusively under EU sovereignty with French datacenters. For German healthcare, French government, EU-regulated finance, or any team where US-CLOUD-Act exposure is a deal-breaker, Scaleway is one of the few S3-compatible options. Compared to AWS S3 in eu-west, Scaleway is cheaper, faster within Europe, and provider-independent. CloudsLinker connects via standard S3 keys + region endpoint, so the same migration tooling that works for AWS / Wasabi / R2 works for Scaleway with no special handling — except for one quirk: Scaleway's multipart upload supports only 1,000 parts, not the AWS-standard 10,000.

Key features of Scaleway Object Storage

EU sovereignty, French ownership

Scaleway is owned by Iliad (France) — no US parent company, no CLOUD Act exposure. Datacenters in Paris, Amsterdam, Warsaw with full GDPR compliance and ISO 27001 certification.

750 GB free for 90 days

New users get 750 GB of free Multi-AZ storage spanning all regions for 90 days, splittable between Multi-AZ and One Zone classes (e.g. 300 GB Multi-AZ + 450 GB One Zone).

Three storage classes

Standard Multi-AZ (multi-zone replication), Standard One Zone (cheaper, single-AZ), Glacier (cold archive, 5 TB max objects). Lifecycle rules tier between them.

Multipart: 1,000 parts max

Scaleway's S3 API supports up to 1,000 parts per multipart upload — different from AWS's 10,000-part limit. CloudsLinker tunes part size accordingly.

Intra-region transfers free

Data movement within the same Scaleway region is free. Inter-region and external egress are billed — relevant when replicating Paris ↔ Amsterdam.

8 MB CLI upload threshold

When using the AWS CLI, files >8 MB automatically trigger Scaleway's multipart upload — a lower threshold than most S3 providers. CloudsLinker handles the boundary internally.

Why connect Scaleway Object Storage to CloudsLinker

CloudsLinker connects to Scaleway Object Storage with S3-style Access Key + Secret + region-specific endpoint (e.g. s3.fr-par.scw.cloud, s3.nl-ams.scw.cloud, s3.pl-waw.scw.cloud). Once connected, transfers run server-to-server using S3 multipart upload — chunked into up to 1,000 parts (Scaleway's specific limit) at 5 MB–5 GB each. The connector handles all three Scaleway regions, supports both Multi-AZ and One Zone storage classes, and works for Scaleway as source, destination, or cross-region replication within the EU.

What you can do with Scaleway Object Storage on CloudsLinker

S3-compatible EU-only transfers

Migrate from AWS S3, Wasabi, B2 or R2 into Scaleway with full multipart-parallel speed — keeping data within EU jurisdiction at every step.

Runs on our servers

Scaleway transfers execute on CloudsLinker infrastructure. Your home or office connection plays no role in throughput.

Scheduled & incremental sync

Hourly / daily / weekly schedules with delta mode — useful for keeping a Paris-region bucket mirrored to an Amsterdam-region bucket for redundancy.

Filter by prefix, size, modified date

Migrate only specific bucket prefixes, skip files > 100 GB, or back up only data modified in the last 30 days.

Common Scaleway Object Storage transfer scenarios

GDPR-compliant backup destination for EU-regulated industries

Healthcare, legal, financial, and government customers operating under GDPR sometimes require backups that never leave EU jurisdiction. Schedule a CloudsLinker incremental from your primary cloud (often AWS S3 in eu-west or OneDrive) to Scaleway in Paris or Amsterdam — all data stays under French/EU-French law, with full data-processing-agreement support and ISO 27001-certified infrastructure.

Migrate AWS S3 → Scaleway for European cost arbitrage and compliance

AWS S3 in eu-west-1 charges higher than Scaleway for equivalent EU-region storage, and AWS's Irish entity remains US-controlled. CloudsLinker copies bucket-by-bucket from S3 to Scaleway via multipart-parallel — initial seed costs AWS egress, but ongoing bills typically drop 30–50 % while gaining EU sovereignty.

Cross-region DR within Europe: Paris ↔ Amsterdam

Even within a single provider, geo-redundancy across regions matters for DR. CloudsLinker schedules nightly incrementals from s3.fr-par.scw.cloud to s3.nl-ams.scw.cloud — both EU regions, low latency, and inter-region billing remains modest at Scaleway's published rates.

Tier cold data: Standard → Glacier (5 TB max objects)

Scaleway Glacier accepts unlimited objects up to 5 TB each at a fraction of Standard pricing. Use a CloudsLinker filter (modified-before-date) to move cold prefixes from Standard Multi-AZ to Glacier within the same bucket — typically 80 % cost reduction for archive workloads.

Software vendor: serve EU customers from EU-only origin

B2B SaaS vendors selling into French / German / Dutch enterprise often need to demonstrate that customer data physically stays in Europe. Run primary on Scaleway in eu-west (FR-PAR or NL-AMS), with CloudsLinker providing on-demand migration tooling for customer onboarding from existing S3 / GCS / Azure buckets.

How to connect Scaleway Object Storage to CloudsLinker

Scaleway uses S3-style Access Key + Secret Key with a region-specific endpoint URL.

Before you start

Create a dedicated Scaleway IAM API key for CloudsLinker — never use account-root credentials:

Sign in to the Scaleway console at https://console.scaleway.com.
Go to IAM in the user menu → API Keys tab.
Click Generate API Key.
Configure:
- Application — select an IAM application (or create one named cloudslinker-migrate)
- Description — e.g. “CloudsLinker S3 access for marketing bucket”
- Expiration — set a reasonable expiry to limit blast radius
Scaleway shows the Access Key and Secret Key once. Copy both immediately.
Apply IAM permissions: scope the application to specific buckets via IAM → Policies with rules like ObjectStorageReadOnly (source) or ObjectStorageFullAccess (destination), restricted to specific Object Storage resources.

Connection steps

In CloudsLinker, click Add Cloud → choose Scaleway.
Enter a display name (e.g. “Scaleway FR-PAR — production”).
Paste the Access Key and Secret Key from step 5 above.
Enter the Endpoint URL matching your bucket’s region:
- s3.fr-par.scw.cloud (Paris)
- s3.nl-ams.scw.cloud (Amsterdam)
- s3.pl-waw.scw.cloud (Warsaw)
Click Confirm — CloudsLinker validates with ListBuckets and shows the connection ready.

Multi-region

If you want to use multiple Scaleway regions, add each as a separate CloudsLinker cloud connection. Inter-region transfers between Scaleway regions are billed at the published rate; intra-region is free.

Revoke access

To revoke CloudsLinker’s IAM API key later: Scaleway console → IAM → API Keys → find the key → Delete. Or rotate by generating a new key first and updating CloudsLinker before deleting the old one.

Scaleway Object Storage upload & download limits you should know

Scaleway is S3-compatible with a few region-specific quirks (the 1,000-part multipart limit is the main one to watch):

Maximum object size: 5 TB on Standard and Glacier classes.
Maximum single PUT: 5 GB. Beyond that, multipart is required.
Multipart parts: 1 to 1,000 per upload — significantly fewer than AWS S3’s 10,000. Part size: 5 MB–5 GB.
CLI multipart trigger: 8 MB when using AWS CLI — files above this auto-switch to multipart.
Storage classes:
- Standard Multi-AZ — replicated across availability zones
- Standard One Zone — single AZ, cheaper, lower durability
- Glacier — cold archive, retrieval fees apply
Free tier: 750 GB total Multi-AZ-equivalent free storage for 90 days (new users). Splittable between Multi-AZ and One Zone.
Beta pricing: 50 % public-beta discount on certain features through May 31, 2026.
Egress: intra-region free; inter-region and external internet egress billed. See Scaleway pricing for current rates.
Regions: FR-PAR (Paris), NL-AMS (Amsterdam), PL-WAW (Warsaw).
API rate limits: Scaleway throttles aggressive patterns; CloudsLinker handles back-off automatically.
Object Lock: supported for WORM retention on Standard buckets.
Bucket / object count: practically unlimited.

Scaleway Object Storage + CloudsLinker — Frequently Asked Questions

Is Scaleway really US-CLOUD-Act-free?

Yes. Scaleway is owned by Iliad SA, a French publicly-traded company, with no US ownership at any tier. Scaleway's datacenters are in France (Paris), Netherlands (Amsterdam), and Poland (Warsaw), operated under EU and member-state law. Compared to AWS Ireland or Azure Europe — both ultimately US-controlled and subject to the CLOUD Act — Scaleway provides genuine EU sovereignty.

What's the maximum object size on Scaleway?

5 TB per object on Standard and Glacier classes. Single PUT capped at 5 GB; anything larger uses multipart upload. Note: Scaleway's multipart limit is 1,000 parts per upload, not AWS's 10,000 — so with 5 GB max parts, the practical multipart ceiling is 5 TB; with smaller chunks, the part count constrains you sooner.

Are transfer fees expensive?

Egress fees apply to external outgoing data and inter-region transfers. Intra-regional traffic (within the same Scaleway region) is free. Specific rates depend on tier and volume; see Scaleway's pricing page for current numbers. For most backup workloads, intra-region replication keeps bills low; egress to external clouds is where charges accumulate.

What's the difference between Standard Multi-AZ and Standard One Zone?

Multi-AZ: data replicated across multiple availability zones in the same region — high durability, slightly higher cost. One Zone: data in a single AZ — cheaper, lower durability since AZ failure means data loss. Use Multi-AZ for primary; One Zone for secondary copies you can recreate.

How does the 750 GB free tier work?

New Scaleway users get 750 GB total free Multi-AZ-equivalent storage for 90 days, splittable between Multi-AZ and One Zone classes. After 90 days, paid rates apply on the full balance. Useful for a one-time migration into Scaleway under the free window, then evaluating ongoing costs.

Are my Scaleway credentials safe with CloudsLinker?

Yes. Access Key and Secret are encrypted at rest with AES-256 and decrypted only inside the active transfer worker. Best practice: create a Scaleway IAM API key scoped to specific buckets via Scaleway IAM rules, separate from your account-wide credentials.

Does Scaleway support Object Lock or WORM retention?

Scaleway supports Object Lock for S3-compatible WORM retention on Standard buckets — useful for ransomware-resistant backups under EU compliance requirements. CloudsLinker preserves Object Lock metadata when copying between Object-Lock-aware providers (Scaleway, AWS S3, Wasabi, B2).

How do I pick a region — Paris, Amsterdam, or Warsaw?

Pick by user latency and any data-residency requirements. FR-PAR for French / Southern Europe customers and SecNumCloud-aligned workloads. NL-AMS for Northern European latency and as a DR replica region for FR-PAR. PL-WAW for Eastern European customers or data-residency requirements specific to Poland.

How does Scaleway compare to OVHcloud or Hetzner?

All three are European S3-compatible alternatives. Scaleway: 3 regions, mature S3 API, French owner, ISO/SecNumCloud certified. OVHcloud: more regions globally, S3-compatible Object Storage, French owner. Hetzner: Storage Box and Object Storage in DE/FI, lowest €/TB but smaller regional footprint. Scaleway is often picked when SecNumCloud or French-government compliance is a requirement.

Is this an official Scaleway partnership?

No. CloudsLinker is a third-party tool that uses Scaleway's S3-compatible API under your IAM API key. Revoke access by deleting the key in Scaleway console → IAM → API Keys.
