Zusammenfassung:	Methods, systems, and apparatus, including a method for providing data. The method comprises receiving a first request from a first virtual machine (VM) to store data, obtaining the data and an access control list (ACL) of authorized users, obtaining a data key that has a data key identifier, encrypting the data key and the ACL using a wrapping key to generate a wrapped blob, encrypting the data, storing the wrapped blob and the encrypted data, and providing the data key identifier to users on the ACL. The method further comprises receiving a second request from a second VM to obtain a data snapshot, obtaining an unwrapped blob, obtaining the data key and the ACL from the unwrapped blob, authenticating a user associated with the second request, authorizing the user against the ACL, decrypting the data using the data key, and providing a snapshot of the data to the second VM.
