Abstract:
Methods, apparatus, and computer-accessible storage media for restoring data from a snapshot to a data volume. The blocks in the volume may be treated as an implicit tree structure, for example a binary tree; each local block corresponds to a block on the snapshot. A local block on the volume may be marked, for example fingerprinted with metadata, to indicate that the local block has not been restored. Initially, the local block at the root node is marked. To restore a local block, the restore process may generate a list indicating all local blocks on a path from the root node of the tree to the target node that have not been restored. The marks in the local blocks are used in generating the list. For each block indicated in the list, children of the block are fingerprinted, and the block is restored from the snapshot.
