1. A method of restoring a backup from a deduplication vault storage, the method comprising: accessing entries in a list of unique blocks in a backup of a source storage at a point in time, the list initially being ordered in a first order, each of the entries in the list being associated with a hash value of the unique block; reordering the list into a second order that matches a numeric order of block addresses of corresponding unique blocks as stored in a vault storage; reading the corresponding unique blocks in the second order from the vault storage; establishing communication between the vault storage and a restore storage; and storing the corresponding unique blocks in the restore storage.
