OnePass for Exchange Mailbox (Classic) is a comprehensive solution that incorporates the traditional backup and message archiving in a single operation. You can move the mailbox messages to a secondary storage and use these messages to function as both backup and archive copy. Stubs are retained on the production storage. The stubs point to the messages that were moved as part of the backup. The archived messages are available for quick and easy retrieval by administrators and end users.
In addition, this integrated agent can age messages and stubs selectively to reclaim space on the primary storage and the secondary storage based on message age in the mailbox.
