Abstract

An improved content indexing (CI) system is disclosed herein. For example, the improved CI system may include a distributed architecture of client computing devices, media agents, a single backup and CI database, and a pool of servers. After a file backup occurs, the backup and CI database may include file metadata indices and other information associated with backed up files. Servers in the pool of servers may, in parallel, query the backup and CI database for a list of files assigned to the respective server that have not been content indexed. The servers may then request a media agent to restore the assigned files from secondary storage and provide the restored files to the servers. The servers may then content index the received restored files. Once the content indexing is complete, the servers can send the content index information to the backup and CI database for storage.

Claims1

Dependent claims

A networked information management system for separately storing previews, the networked information management system comprising:

a preview database;
a backup and content indexing database;
and
a content indexing service having one or more first hardware processors, wherein the content indexing service is configured with first computer-executable instructions that, when executed, cause the content indexing service to:
receive a restored version of a secondary copy, wherein the secondary copy corresponds to a first data file;
parse the restored version of the secondary copy;
extract one or more keywords corresponding the first data file based on the parsing of the restored version of the secondary copy;
generate a preview of the restored version of the secondary copy;
store the generated preview of the restored version of the secondary copy in the preview database;
and
store, in the backup and content indexing database, the one or more extracted keywords and a path to a storage location of the generated preview in the preview database.
