Abstract
Generally described, one or more aspects of the present application correspond to techniques for managing snapshots in a partially encrypted state and providing access to partially encrypted snapshots. These snapshot management techniques allow a snapshot that is being encrypted to be accessed prior to the encryption being completed. Such a snapshot may have some blocks that have been encrypted, and other blocks that have not yet been encrypted. In order to provide access to such a snapshot in a partially encrypted state, a system may allow the encryption status of the blocks in the snapshot to be checked at the block level instead of at the snapshot level (or at some other intermediary level therebetween), according to some embodiments. By doing so, the system can reduce the delays resulting from snapshots that are locked during the encryption process.
