Abstract
Systems and methods are provided for linking data. In one implementation a method is provided. A first backup is generated. The first backup includes a first hierarchical file system, where entries in the first hierarchal file system reference corresponding source data of the first backup. A second backup is generated. The second backup includes a second hierarchical file system, where the second hierarchical file system includes one or more links referencing source data of the first backup.

17. A method comprising:
-
generating a second file system entry in a file system hierarchy, the second file system entry having a reference to source data already referenced by a first file system entry; and associated the second file system entry with the first file system entry to form a sibling chain of links. - View Dependent Claims (18, 19, 20)

21. A method comprising:
-
generating a first backup, the first backup including a first hierarchical file system, where entries in the first hierarchical file system reference corresponding source data of the first backup; generating a second backup, the second backup including a second hierarchical file system, where the second hierarchical file system includes one or more link entries referencing source data of the first backup; receiving a search query associated with particular source data; search for entries in the first and second backups referencing the source data associated with the search query; and presenting search results including an entry from the first file hierarchical system and at least one link entry from the second hierarchical file system.

22. A data structure, comprising:
a hierarchical file system having a plurality of entries, the entries having a reference to particular source data, where an entry in the plurality of entries is a first folder entry, the first folder entry having a one or more child entries, and where an entry is a second folder entry, the second folder entry being a link referencing identical source data referenced by the first folder entry.

23. A method comprising:
-
initiating a backup; identifying data to be included in the backup; locating a previous backup; comparing data of the previous backup with the data to be included in the backup to identify new data to be stored and old data that is unchanged from the previous backup; and storing the new data and a plurality of links to the old data. - View Dependent Claims (24, 25)
