Spanning Backup: sovereignty score and 8 European alternatives

Spanning Backup is a cloud-to-cloud backup and recovery service for Microsoft 365, covering Exchange Online, SharePoint Online, OneDrive for Business and Microsoft Teams, and for Google Workspace, covering Gmail, Google Drive and Shared Drives, Calendar and Contacts. A Salesforce backup is also offered. The service is delivered as SaaS. The operating company, Spanning Cloud Apps, LLC, presents itself as a Kaseya company.

Kaseya lists Miami, Florida, as its headquarters, so the parent is a US company and no separate foreign owner is named. The vendor states that Microsoft 365 backup data can be stored in South Africa, and that Salesforce backup data is stored in the United Kingdom, Canada and Australia. For Google Workspace it links to a global data-centre page without naming regions, and no EU storage region is stated. For a European organisation, EU storage is therefore not confirmed by the vendor, US jurisdiction applies to the parent company, and the storage region should be checked in the contract before personal data is backed up.

Why digital sovereignty matters with Spanning Backup

Spanning Backup is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

Spanning Backup hosts data outside the EU (US, OTHER). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

Spanning Backup is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Spanning Backup together with your other vendors and gives a total score, a heatmap and the main risk drivers.
