An update to the Lync 2013 Enterprise Backup script

I have now updated the Backup script for Lync 2013 Enterprise to support a topology with a mirrored back-end server (SQL). The script is tested on systems with and without a mirror configuration.

Also, the script is updated to take backup of the persistent chat server. If none is deployed in your topology, either ignore the error message, or REM out that part of the script.

Thanks to Dino Caputo for alerting about the error in my script!!

The script can be found right here, and the other links are all updated.
