20. A computer-readable storage medium, excluding transitory propagating signals, storing instructions that, when executed by a processor, cause the processor to execute a method of enabling a user to search from a user-device for content stored in a file archive of an information management system, based on multi-dimensional indexing of a plurality of files archived to the file archive, the method comprising: providing a search interface; receiving a search criterion; searching, based on the search criterion, indexing information about the file archive, which comprises respective archive copies of the plurality of files archived to the file archive, wherein the indexing information comprises, for each respective archive copy in the file archive: (i) a file attribute index generated by a media agent when the respective file was archived to the file archive, and (ii) a content index generated by at least one of the media agent and a user-device when the respective file was archived to the file archive, wherein the content index indexes at least part of the contents of the file being archived based on at least one of: text content, picture content, video content, and audio content, and wherein the search criterion indicates at least one of: text content, picture content, video content, and audio content to be searched for; and performing an action on a first archive copy in the file archive, which archive copy satisfies the search criterion used in the searching, wherein the action comprises providing a fast-forward progression through a plurality of smaller portions of the archive copy without individually restoring the smaller portions of the archive copy, wherein the fast-forward progression is based on searching at least one of the file attribute index and the content index of the archive copy, and wherein each of the smaller portions of the archive copy is indexed at least once, during the archiving of the file to the file archive, in at least one of the file attribute index and the content index of the archive copy, and may be restored to the user-device without the other smaller portions of the archive copy also being restored.
20. A computer-readable storage medium, excluding transitory propagating signals, storing instructions that, when executed by a processor, cause the processor to execute a method of enabling a user to search from a user-device for content stored in a file archive of an information management system, based on multi-dimensional indexing of a plurality of files archived to the file archive, the method comprising: providing a search interface; receiving a search criterion; searching, based on the search criterion, indexing information about the file archive, which comprises respective archive copies of the plurality of files archived to the file archive, wherein the indexing information comprises, for each respective archive copy in the file archive: (i) a file attribute index generated by a media agent when the respective file was archived to the file archive, and (ii) a content index generated by at least one of the media agent and a user-device when the respective file was archived to the file archive, wherein the content index indexes at least part of the contents of the file being archived based on at least one of: text content, picture content, video content, and audio content, and wherein the search criterion indicates at least one of: text content, picture content, video content, and audio content to be searched for; and performing an action on a first archive copy in the file archive, which archive copy satisfies the search criterion used in the searching, wherein the action comprises providing a fast-forward progression through a plurality of smaller portions of the archive copy without individually restoring the smaller portions of the archive copy, wherein the fast-forward progression is based on searching at least one of the file attribute index and the content index of the archive copy, and wherein each of the smaller portions of the archive copy is indexed at least once, during the archiving of the file to the file archive, in at least one of the file attribute index and the content index of the archive copy, and may be restored to the user-device without the other smaller portions of the archive copy also being restored. 23. The computer-readable storage medium of claim 20 wherein the method further comprises: mounting the archive copy that satisfies the search criterion used in the searching to a drive accessible by the user-device using a network file system (NFS) interface without also mounting archive copies that do not satisfy the search criterion; restoring to the user-device a first smaller portion of the archive copy in response to a user command indicating the first smaller portion; and restoring to the user-device, without receiving a further user command, a second smaller portion of the archive copy which, according to the content index, is immediately before or immediately after the first smaller portion of the archive copy in the fast-forward progression; and wherein the first and second smaller portions are restored without also restoring the other smaller portions of the archive copy.
