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 1):
A computer-implemented method comprising:\n receiving a request for copying data from a source region comprising one or more first data storage servers to a destination region comprising one or more second data storage servers,\n wherein the one or more first data storage servers establish a data storage volume in the source region for storing data generated by a virtual machine instance and encrypted by an independent software process according to a plaintext volume key provided by a key management service; \n wherein the software process is executed independently of the virtual machine instance and receives the data to be encrypted from the virtual machine instance, such that the virtual machine instance does not have access to the plaintext volume key, and \n wherein the data storage volume is further 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; \n obtaining, in response to the request for copying data, the source region encrypted volume key from the key management service; causing decryption of the source region encrypted volume key based, at least in part, on the source region client master key associated with the virtual machine instance, wherein the decryption results in the plaintext volume key; causing encryption of the plaintext volume key based, at least in part, on a destination region client master key associated with the virtual machine instance to obtain a destination region encrypted volume key; making the destination region encrypted volume key available in the destination region; and causing transmission of the encrypted data to the destination region.
