Abstract: A file-level snapshot access service provides direct access to individual files included in a snapshot for virtual volume of a block-storage service without requiring a volume to be re-created from the snapshot, attached to a computing device, or mounted in a file system. For example, a user/client may directly retrieve individual files from specified snapshots via a user interface/API of the file-level snapshot access service. Additionally, the file-level snapshot access service is configured to provide a listing of files included in a given snapshot. In some embodiments, a file-level snapshot access service may provide direct access to individual files included in snapshots generated for other types of storage systems, such as an object-based storage system.

Abstract: Generally described, one or more aspects of the present application relate to a public snapshot service for creating and managing block-level snapshots. For example, the public snapshot service can create a snapshot based on (i) a specification of a parent snapshot to be used as a basis for a given snapshot, and (ii) a specification of the data blocks to be backed up in the given snapshot. The data blocks in the snapshot may be stored in a specific storage path structure that facilitates computation of a block difference with respect to the parent snapshot.

Abstract: Generally described, one or more aspects of the present application relate to a public snapshot service for associating a block-level snapshot with certain snapshot properties that indicate a block load order, and creating a block storage volume from the snapshot by loading the blocks in the snapshot onto the block storage volume in the block load order indicated by the snapshot properties associated with the snapshot.

Abstract: Generally described, one or more aspects of the present application correspond to techniques for creating multiple encrypted block store volumes of data from an unencrypted source. These encryption techniques can use a transform fleet as an intermediary use between the unencrypted source and the encrypted volumes. The transform fleet can obtain data of the volume from one or both of two sources—an object storage “snapshot” a block storage “source volume”—and can then apply the appropriate encryption key for performing the encryption of a particular volume.

Abstract: A router receives a request to access a resource. In response to the request, the router identifies routing metadata comprising first metadata specifying a first location of the resource and a first merit value and second metadata specifying a second location of the resource and a second merit value. The router determines, based at least in part on the first merit value of the first metadata and the second merit value of the second metadata, an authoritative state of the resource associated with the first location or the second location. Based at least in part on the determination, the router identifies a preferred location for a new resource. In the event of a rollback, merit values are assigned to cause a reversal of the preferred path for the creation of new resources.

Abstract: Generally described, one or more aspects of the present application correspond to techniques for creating encrypted block store volumes of data from unencrypted object storage snapshots of the volumes. These encryption techniques use a special pool of servers for performing the encryption. These encryption servers are not accessible to users, and they perform encryption and pass encrypted volumes to other block store servers for user access. The encryption context for the volumes can be persisted on the encryption severs for as long as needed for encryption and not shared with the user-facing servers in order to prevent user access to encryption context.

Abstract: A data storage service redundantly stores data and keys used to encrypt the data. Data objects are encrypted with first cryptographic keys. The first cryptographic keys are encrypted by second cryptographic keys. The first cryptographic keys and second cryptographic keys are redundantly stored in a data storage system to enable access of the data objects, such as to respond to requests to retrieve the data objects. The second cryptographic keys may be encrypted by third keys and redundantly stored in the event access to a second cryptographic key is lost.

Abstract: Conditions are enforced to prevent unintended deletion of data stored by a data storage system. For example, to delete a collection of data, a condition on the collection of data's size may be enforced. The collection may be required to be empty, for example. In addition, a condition that there not exist a pending data processing operation that can affect fulfillment of the condition on the collection of data's size is also enforced.
