A request is received to restore a file at a deduplicated storage system to a client. The file resides at the storage system as a synthetic file based on a base file at the storage system. The request includes an indication that the base file is also present at the client. Metadata generated during a backup of the file to the storage system is reviewed. The metadata includes references to data determined to be in the base file at the storage system, and references to other data determined to not be in the base file at the storage system. The other data determined to not be in the base file is read from the storage system and transmitted to the client. Upon receipt, the client assembles the requested file using the base file present at the client and the other data determined to not be in the base file.
