Microsoft Lync Server Backup RRS feed

  • Question

  • Hi, 

    I understand that to backup the Lync environment we need to run a series of commandlets etc that part I am aware of. However regarding the Edge server in the DMZ, do we need to back anything up on this or is all the config held in the CMS. Also as I understand we do not back up the DBs on the SQL side as they do not hold the CMS? Am I correct? 

    Many Thanks

  • Hi,

    You are right , you can export the configuration from CMS which includes edge server config as well.

    It's a good idea to take a backup of public certificates and persistant route information (if any) from edge box.

    Also following article would be helpful of planning the backup; http://technet.microsoft.com/en-us/library/hh202194

  • Hi,

    We do not need to backup Edge Server separately as the settings of external user access have been included in CMS.

    As my understanding, the Central Management Store file (Xds.mdf) is located in the backend database. All Lync Server 2010 servers have a local replica of CMS. One of the Front-End Servers is the Central Management Server (active CMS master server) that copies the CMS to all other Lync servers. For backing up CMS, we can use Export-CsConfiguration to import the CMS database as CMS xml file. For persistent user data (Rtc.mdf database), we need to use Dbimpexp.exe to backup. For Archiving database (LcsLog.mdf), Monitoring call detail record database (LcsCDR.mdf) and Monitoring QoE database (QoEMetrics.mdf), we need to use SQL Server database tool, such as SQL Server Management Studio to backup them on the SQL side.

    Regards,

    Kent

  • Hi,

    Nothing, requires a backup on the Edge or in the whole Lync deployment except the CMS and the Back End (for enterprise deployment) or the Fronf End (for the standard deployment). However, you may use bare metal backup for fast restoration.

    To restore, either to restore the bare metal as is or rebuild the machine with the same name and run the deployment wizard.

    Note that bare metal backup for Lync is not tested by Microsoft and not yet supported.

    and as Turgay Ongun mentione in http://social.technet.microsoft.com/Forums/en-US/ocsplanningdeployment/thread/0dbf8108-611c-4500-a0bb-a52a4e666d7f

    This may cause a certain data loss - especially on the conference directories.

    Why not to take look at "Backing Up and Restoring Lync Server 2010" guide.
