Message-level backup and restore using DS-MLR

DS-Message Level Restore (DS-MLR) is a Windows service that searches for email messages based on a user defined filter, then transforms each email message into a data stream, and passes this stream to DS-Client for processing for backup to DS-System. DS-MLR treats each email object as a separate backup item. During backup, DS-Client scans all items and backs up only the new or changed items. Changed items are processed as deltas and only the changes are sent to DS-System. Email messages are saved (along with any attachments) as individual objects on DS-System.

DS-MLR can perform message-level backup and restore for the following types of email servers:

Microsoft Exchange Server (using MAPI)

Microsoft Outlook

IBM Domino and Notes

Novell GroupWise

IMPORTANT:  The DS-MLR service must be installed on the email server as part of the DS-Recovery Tools installation process, and DS-Recovery Tools must be enabled in DS-System by your service provider. For detailed instructions see the Client Software Installation Guide and DS-System User Guide.
