Since Office Communications Server 2007 is released to manufacturing and organizations are deploying in their production environments it's very important to backup your OCS environment correctly. More information on this topic see:
Main chapters in these documents are:
Backing up your OCS environment globally by:
lcscmd /config /action:export /level:global,pool /configfile: <drive>:\<path>\<filename>.xml /poolname:[name of pool for which settings are to be exported]
Backup up your OCS environment at machine level:
lcscmd /config /action:export /level:machine /configfile:C:\Backup\OCS1Serversettings.xml /fqdn:ocspool1server1.contoso.com
Make sure these output files are correctly saved and available when needed.
