Abstract:
A data storage management process is directed to aspects of managing encrypted data via data storage volumes in conjunction with a service provider computer network that hosts virtual machine instances. A volume can be created and configured for managing encrypted data with an encrypted version of a volume key. The volume can be attached to a virtual machine instance such that the virtual machine instance accesses the volume in a transparent fashion based on the volume key. Encrypted data specific to the volume can be copied across multiple regions of data storage each associated with distinct encrypted versions of a volume key corresponding to the volume.

Claim (Index 5):
A system comprising:\n one or more computers including processors and memory corresponding to one or more first data storage servers, the one or more first data storage servers forming a data storage volume in a source region, the data storage volume maintaining data generated by a virtual machine instance in the source region, wherein the data generated by the virtual machine instance is encrypted by an independent software process according to a plaintext volume key received from a key management service, wherein the virtual machine instance does not have access to the plaintext volume key, and wherein the data storage volume is associated with a source region encrypted volume key that is generated by encrypting the plaintext volume key with a source region client master key associated with the virtual machine instance; one or more computers including processors and memory corresponding to one or more second data storage servers; and one or more computers including processors and memory, the memory including instructions that, upon execution, cause the one or more computers to:\n receive a request for copying data corresponding to the data storage volume from the source region to a destination region comprising the one or more second data storage servers; \n obtain, in response to the request, the volume key associated with the data storage volume from the key management service; \n cause the key management service to encrypt the volume key to generate a destination region encrypted volume key associated with a client associated with the destination region; and \n make the encrypted data available to the destination region, wherein the encrypted data is associated with the destination region encrypted volume key in the destination region.
