Abstract: The present application relates to a public snapshot service for creating and managing block-level snapshots. The public snapshot service can create a snapshot using (i) a specification of a parent snapshot to be used as a basis for a snapshot, and (ii) a specification of the data blocks to be backed up in the 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. Storage locations for each block that comprise the snapshot can be enumerated on a snapshot manifest. Identification of storage location for a requested snapshot block can be improved using a manifest index. Snapshots can be configured to enable writing at the sub-block level. Subsequent modifications made to block storage volume that forms the basis of the snapshots can be backed up as a sub-block level operation.

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.
