Update Feb 14 2016: Amazon Cloud Drive is now a supported cloud provider for personal cloud users see: https://blog.storagemadeeasy.com/amazon-cloud-drive-is-now-available-to-sme-personal-cloud-users/
Amazon have made some changes on access to their Cloud Drive which means that we will no longer be able to support this as a Cloud Provider as they do not wish external systems to interact with the data contained.
Existing users of this provider are likely to find that they will no longer be able to access their files using this provider. The Amazon Cloud Provider will remain as part of an account until it is removed. It will not be then accessible and it will not be accessible from new accounts from today.
If Amazon change their policy on this then we will re-introduce it.
