Claim Text:
1. A method for processing backup data, comprising: receiving, from a protected system, a predetermined subset of metadata associated with backup data at a data router in a backup system, wherein the predetermined subset of metadata includes (a) an operating system associated with the protected system, (b) a file type from which the backup data was obtained, and (c) backup-related metadata, including one or more of the following: (1) a backup level associated with the backup data and which specifies if a backup performed on the protected system and which caused the backup data to be generated is associated with one or more of the following: a full backup, an incremental backup, or a differential backup, (2) a backup retention policy associated with the backup data and which specifies a policy for retaining the backup data on the backup system, or (3) a backup data type associated with the backup data and which specifies if the backup performed on the protected system and which caused the backup data to be generated is associated with one or more of the following: a file-based backup or a block-based backup; using a processor on the data router in the backup system to generate a locality-sensitive hash key for the backup data based at least in part on (a) the operating system, (b) the file type, and (c) one or more of the following: (1) the backup level associated with the backup data, (2) the backup retention policy associated with the backup data, or (3) the backup data type associated with the backup data, wherein: assigning the backup data to one of a plurality of deduplication nodes included in the backup system based at least in part on the locality-sensitive hash key.
