Search filtered file system using secondary storage, including multi-dimensional indexing and searching of archived files

摘要

Techniques for enabling user search of content stored in a file archive include providing a search interface comprising a search rules portion and an action rules portion, receiving a file archive search criterion comprising at least one search rule, and searching the file archive using the search criterion. The techniques also include generating a set of files filtered using the search criterion and performing an action specified in the action rules portion on a file included in the set of files.

主权项

1. A method of multi-dimensional indexing of a file being archived to secondary storage in an information management system, comprising:
receiving, by a media agent component of the information management system that has been identified for archiving a file, a command to begin multi-dimensional indexing of the file being archived; performing multi-dimensional indexing of the file, by the media agent, in response to receiving the command, wherein the multi-dimensional indexing comprises:
(i) generating, by the media agent, a file attribute index for the file,
wherein the file attribute index includes extrinsic information about the file and is independent of contents of the file, and(ii) creating, by the media agent, a content index for the file,
wherein the content index is based on at least one of: text content, and image content, and audio content within the file; archiving the file to secondary storage, by the media agent,
wherein the file archiving operation includes dividing the file into multiple independently accessible smaller portions of the file being archived,wherein any one independently accessible smaller portion of the file being archived is identified at least once in at least one of the file attribute index and the content index, and
may be later restored from secondary storage, to a user, without also restoring the other independently accessible smaller portions of the file being archived; storing, by the media agent, the file attribute index to a first location, the content index to a second location, and the archived file to a third location; and based on the multi-dimensional indexing of the archived file, providing to a user of the information management system a fast-forward progression through a plurality of the independently accessible smaller portions of the archived file without individually restoring each portion in the plurality from secondary storage,
wherein the fast-forward progression is based on searching of at least one of the file attribute index and the content index within the information management system.
