CloudFiler maintains copies of your messages on secure servers on Amazon's AWS service. 3 copies are kept of each email and on 3 separate servers. If one server or disc fails, a new one is automatically spun-up and the data is replicated across. This data is also backed up.

Licensees of the Professional and Enterprise tiers can also use CloudFiler connectors to sync the data to either their own servers or other services. When a connector is used, the data is still maintained securely on our servers but is also synced to wherever you have configured it to go.

During our early adopter period all customer tenants are hosted on servers in the UK. In the future and depending on your licensing tier you will be able to choose where in the world your data is hosted.
