1. A method for restoring a backup of a storage media, the method comprising:
- receiving a request for a cluster data,the request associated with the backup,a backup database comprising the backup,the backup database further comprising a plurality of cluster data,each of the plurality of cluster data being unique wherein single-instance storage within the backup database is provided;
reading the cluster data from the backup database; and
providing the cluster data read from the backup database.

17. A method for restoring a backup of a storage media comprising:
-
receiving a request for a cluster data, the request associated with a backup, the backup comprising a set of cluster indexes and a first set of cluster hashes, each index of the set of cluster indexes corresponding to a single cluster hash of the first set of cluster hashes, the backup associated with a backup database, the backup database comprising a first plurality of cluster data, the backup database further comprising a second set of cluster hashes, each of the second set of cluster hashes uniquely corresponding to one of the first plurality of cluster data, each of the first plurality of cluster data uniquely corresponding to one of the cluster hashes in the second set of cluster hashes, each of the first plurality of cluster data being unique wherein single-instance storage within the backup database is provided; reading the cluster data from the backup database; and providing the cluster data read from the backup database. - View Dependent Claims (18, 19, 20)
