Archiving Server requires the Microsoft SQL Server database software to store the archive data. You must install Microsoft SQL Server on the computer that will host the Archiving Server database. This can be the same computer that runs Archiving Server, the computer that runs Monitoring Server, the database for the Monitoring Server, or a dedicated database server for archiving. You can also use the same SQL instance that you use for the back-end database of a Front End pool. For best performance, you should deploy the Archiving database on a computer that is separate from the Central Management store. For details about collocating Microsoft Lync Server 2010 components, see Supported Server Collocation in the Supportability documentation.

Lync Server 2010 supports the following 64-bit versions of SQL Server:

SQL Server 2008 Express, SQL Server 2008 R2 Express, and SQL Server 2005 Express Edition are not supported. For additional SQL Server requirements and restrictions, see Database Software and Clustering Support in the Supportability documentation.

If the account used to publish the topology has the appropriate administrator rights and permissions, you can create the archiving database (LcsLog) when you publish your topology. You can also create the database later, including as part of the installation procedure.
