Abstract: Systems and methods for performing backup operations and other secondary copy operations for mail servers, such as Exchange servers, are described. In some cases, the systems and methods perform multi-streaming backup and other copy operations using a single mailbox agent, which launches backup streams via a coordinator that determines when to launch streams, at what mailboxes (or folders) to launch the streams, and so on. The coordinator communicates with controllers at different machines (e.g., servers) to be backed up, and may assign streams, mailboxes, and so on, to the different controllers, which perform the backup operations for their assigned mailboxes and/or clients.

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.
