Achieve GDPR compliance, predictable costs, and ransomware protection for your Synology NAS backups using a European S3-compatible cloud.

Key Takeaways

  • Secure your Synology backups in EU-only data centers to achieve GDPR compliance and digital sovereignty by design.
  • Eliminate unpredictable cloud costs with a storage model that features zero egress fees, no API call charges, and no minimum storage duration.
  • Protect your backup data from ransomware by using S3 Object Lock to create immutable, tamper-proof copies of your critical information.

For IT leaders and MSPs, configuring Synology Hyper Backup to an S3 target is standard practice for achieving robust 3-2-1 data protection. The challenge, however, lies in selecting a storage partner that guarantees cost predictability and aligns with strict EU regulations like GDPR. Storing data outside the EU introduces risks related to data sovereignty and potential exposure to laws like the CLOUD Act. Impossible Cloud provides a sovereign, S3-compatible storage solution engineered in Europe, for Europe. It eliminates egress fees and API call costs, offering a financially predictable and compliant platform to fortify your Synology backups.

Achieve Full Data Sovereignty for Synology Backups

A strong majority of EU decision-makers now demand European solutions for critical data infrastructure. Using Synology Hyper Backup with a sovereign S3 storage target ensures your data stays within predefined European regions. This approach directly addresses GDPR compliance requirements and avoids CLOUD Act exposure completely. Our platform operates exclusively in certified European data centers with country-level geofencing. This architecture provides the legal certainty needed for regulated workloads, with over 70% of companies viewing EU data centers as a critical selection criterion. This focus on localization is the first step toward a resilient backup strategy.

Eradicate Unpredictable Fees from Your Backup Budget

Many businesses feel locked into cloud providers due to complex pricing that includes variable egress and API call fees. A transparent economic model is a primary driver for switching providers, cited by a significant share of IT leaders. Impossible Cloud offers a predictable cost structure for your Synology S3 cloud backup. Our pricing model is built on three core principles:

  • Zero egress fees
  • Zero API call costs
  • No minimum storage duration

This model ensures your total cost of ownership is transparent and stable month after month. For MSPs, this predictability allows for the creation of defensible margins for Backup-as-a-Service offerings. This financial clarity transforms budget planning from a reactive exercise to a strategic advantage.

Fortify Backups Against Ransomware with Immutability

Ransomware remains a top threat, making immutable backups a non-negotiable part of any modern disaster recovery plan. Our platform integrates S3 Object Lock, enabling you to create tamper-proof copies of your Synology Hyper Backup data. This feature prevents files from being altered or deleted for a defined period, rendering ransomware attacks on your backups ineffective. Immutable backups provide an auditable, secure retention mechanism essential for compliance. Implementing this protection requires just a single setting during bucket creation. This simple step provides a powerful defense, ensuring your last line of defense remains intact when you need it most.

Leverage Full S3 Compatibility for Flawless Integration

True S3 compatibility goes beyond basic object operations, a fact critical for complex tools like Synology Hyper Backup. Our fully S3-compatible object storage supports advanced features like versioning and lifecycle management out of the box. This ensures your existing scripts and applications continue to work without any code rewrites. Furthermore, our “Always-Hot” architecture guarantees all data is immediately accessible, with 100% of objects ready for restore. This model eliminates the following operational risks:

  1. Restore delays from tiered storage
  2. Unexpected fees for data retrieval
  3. API timeouts during large recovery jobs
  4. Complex lifecycle policy management

This consistent performance simplifies operations and strengthens your overall recovery posture.

Drive Predictable Margins for MSPs and Channel Partners

For our partners, predictable margins are the foundation of a profitable service offering. Our commercial model is partner-ready by design, eliminating the variable costs that erode profitability. MSPs benefit from a multi-tenant console with robust IAM controls, including MFA and RBAC for secure client management. Automation via our API and CLI simplifies onboarding and daily operations for hundreds of tenants. Recent distribution agreements with api in Germany and Northamber plc in the UK have expanded local access for resellers. This growing ecosystem provides the tools and support needed to build scalable, high-margin backup services.

Execute a Smooth Migration in 4 Steps

Migrating your Synology Hyper Backup tasks to a new S3 storage target is a straightforward process. Following a clear plan minimizes risk and ensures a seamless transition with zero downtime for your backup routines. We recommend a four-step approach for a successful migration:

  1. Configure New S3 Target: In Hyper Backup, create a new backup destination using your Impossible Cloud endpoint, Access Key ID, and Secret Key.
  2. Replicate Backup Tasks: Re-create your existing backup jobs, pointing them to the new S3 target and applying your desired rotation and retention settings.
  3. Run an Initial Integrity Check: Perform a test backup of a small but critical dataset and run an integrity check to validate the connection and permissions.
  4. Execute a Test Restore: Restore a few files or a folder from the new backup set to a separate location to confirm the end-to-end recovery process works as expected.

This structured approach validates the entire workflow before you transition all your production backup tasks.

FAQ

Is Impossible Cloud's storage fully compatible with Synology Hyper Backup?

Yes, Impossible Cloud provides a fully S3-compatible object storage solution that integrates seamlessly with Synology Hyper Backup. It supports all necessary S3 API functions, including advanced features like S3 Object Lock for creating immutable backups.

How does your pricing model benefit Synology backup users?

Our pricing model is designed for predictability. We charge for storage used and nothing more. There are no egress fees for restoring data, no charges for API calls made by Hyper Backup, and no minimum storage durations, which eliminates the hidden costs common with other cloud providers.

Can I restrict my Synology backup data to a specific country?

Yes. Impossible Cloud offers country-level geofencing. You can select a storage region within a specific EU country, and we guarantee your data, including all replicas and metadata, will remain within that legal jurisdiction.

What makes your platform a good choice for MSPs managing multiple Synology devices?

Our platform is partner-ready. It includes a multi-tenant console for managing multiple clients, fine-grained IAM controls with MFA and RBAC, and full automation capabilities via API/CLI. Combined with our predictable pricing, it allows MSPs to build scalable and profitable Backup-as-a-Service offerings.

How does the EU Data Act affect my choice of a backup storage provider?

The EU Data Act, applicable from September 2025, mandates data portability and interoperability. Our platform is built on open standards with full S3 compatibility, ensuring you can easily move your data at any time without vendor lock-in, in full alignment with the Act's principles.

What is the benefit of an 'Always-Hot' architecture for disaster recovery?

For disaster recovery, speed is critical. An 'Always-Hot' architecture ensures every piece of your backup data is instantly available for restore. This eliminates the delays and potential API failures associated with retrieving data from cold storage tiers, leading to faster and more reliable recovery times (RTO).
