How much can European organizations save on egress fees with this solution?

Eliminating egress fees reaching $0.12/GB on other platforms fundamentally alters total ownership costs. This approach avoids structures where internet egress costs 33% more than AWS rates, providing significant financial relief for long-term data retention strategies.

What specific cost disadvantages do hyperscalers impose compared to sovereign alternatives?

Hyperscaler economics rely on tiered structures where internet egress costs 33% more than AWS rates. Additionally, these fees sit 38% above Azure fees, creating variability that complicates budget forecasting for organizations managing large-scale backup targets.

Why is relying solely on data localization insufficient for true digital sovereignty?

The EU currently imports over 80% of necessary digital products, creating strategic weakness residency rules cannot fix. True sovereignty requires European authority over infrastructure code, not just keeping data bits physically located within continental borders.

What operational risk exists when using geo-distributed swarm storage for backups?

Data becomes inaccessible if the swarm quorum fails, demanding rigorous monitoring of underlying physical infrastructure. Operators must manage node availability themselves rather than relying on traditional provider service level agreements for guaranteed uptime.

How does the Cubbit and Commvault integration address regulatory compliance requirements?

This integration creates a verifiable chain of custody satisfying strict mandates like NIS2 and DORA. It ensures cryptographic keys remain under local control while anchoring European backup targets within continental borders to mitigate foreign dependency.

Digital sovereignty needs local code, not just borders

Global data volume will triple by 2027. Centralized storage models cannot scale to meet this demand while satisfying sovereign infrastructure requirements. The partnership between Cubbit and Commvault offers a functional countermeasure to foreign dependency by anchoring European backup targets within continental borders. This alliance merges Commvault's cyber-durability engines with Cubbit's geo-distributed S3 storage, creating a verifiable chain of custody for strict regulatory mandates.
