Abstract: Techniques for global single instance indexing for backup data are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for indexing backup data. The method may comprise generating a content hash for an item being backed up. The item may be associated with a resource name and the content hash may be used as an identifier in backup and indexing. The method may further comprise saving an entry for the item in an index database. The entry may comprise a resource list which may comprise the resource name and a reference count associated with the resource name. Moreover, the method may comprise setting a value for the reference count.

Abstract: Techniques for virtual archiving are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for performing virtual archiving comprising applying archiving rules to a backup catalog, generating a virtual archive catalog based at least in part on a result of applying archiving rules to the backup catalog, determining a backup image associated with the virtual archive catalog becoming expired and converting the backup image into an archive image.

Abstract: A method of intelligently copying recovery points from a primary storage device to a secondary storage device is presented. The decision on how to copy the recovery points depends upon the backup copy policy as well as the availability of previous backups on the secondary storage device.

Abstract: A system or method for granular application data lifecycle sourcing from a single backup is disclosed. In one embodiment of the method, a computer system periodically creates a primary backup copy of data stored on a storage system in order to create a plurality of primary backup copies. The computer system also periodically creates a secondary backup copy of data stored on the storage system in order to create a first plurality of secondary backup copies, wherein each of the secondary backup copies of the first plurality is created in part by copying data from a respective one of the primary backup copies. The periodicity of creating the primary backup copies, however, is distinct from the periodicity of creating the secondary backup copies of the first plurality. The computer system can also periodically create another secondary backup copy of data stored on the storage system in order to create a second plurality of secondary backup copies.

Abstract: Techniques for intelligent content indexing are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for performing intelligent content indexing comprising indexing by one or more processes associated with a client an initial full set of data of the client to create an index of the client data, detecting a change in the client data, and modifying the index to reflect the change in the client data.

Abstract: Synthesized backup set catalogs are created to more efficiently create synthetic full backups of a data volume or to more efficiently restore a data object of the data volume. In one embodiment, the synthesized backup set catalog comprises n entries corresponding to n data objects, respectively, of a data volume being backed up. The synthesized backup set catalog can be created with the creation of an incremental backup of the data volume. Each entry of the synthesized backup set catalog may contain a backup identification (ID), wherein each backup ID identifies at least one of two backup sets of the data volume.
