Microsoft Outlook backups (DS-MLR)
DS-Client supports the backup and recovery of Microsoft Outlook data using DS-MLR. 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. You can perform message-level backups and restore email data at the message level to the original location or an alternate location.
IMPORTANT: The DS-MLR service must be installed and running on the same machine where the email messages are stored and DS-Recovery Tools must be enabled in DS-System by your service provider. For more information, see the Client Software Installation Guide and DS-System User Guide.
