To use the backup procedures covered in this guide, you need to install the backup tools on one or more servers from which you want to perform backup procedures, as specified in your backup and restoration strategy. If your backup and restoration strategy requires administrative tools to be run from one or more separate computers, you must install the tools on each computer to be used. The tools required to complete the procedures in this guide include the following:

• Office Communications Server 2007 R2 administrative tools, which are used for much of the ongoing administration of Office Communications Server. These tools include the Office Communications Server snap-in, along with other tools used to manage some of the optional components, such as Group Chat and Communicator Web Access. Most Office Communications Server 2007 R2 tools can be installed on any server in the domain running Office Communications Server 2007 R2, as well as on other computers (such as administrative consoles), except for the Group Chat Server Configuration Tool, which is automatically installed by default on each computer running Group Chat Server or the Group Chat Compliance service. For details about these administrative tools, see Administrative Consolesin the Planning and Architecture documentation.
  
  
• LCSCmd.exe, which is used to export settings to the backup location (and to import them, in the event that they must be restored). This tool is available on any computer in the domain on which the Office Communications Server 2007 R2 administrative tools are installed. By default, LCSCmd.exe is in the \Program Files\Common Files\Microsoft Office Communications Server 2007 R2 folder on the computer on which the administrative tools are installed. For details about this tool, see Administrative Consolesin the Planning and Architecture documentation.
  
  
• Communicator Web Access snap-in, which is used to export settings for Communicator Web Access virtual servers. This tool is available on any server in the domain on which Office Communications Server 2007 R2 administrative tools are installed. For details about this tool, see Administrative Consolesin the Planning and Architecture documentation.
  
  
• Database tools:
  
  
  • To back up databases on Standard Edition servers, and to restore the database on any Standard Edition (in the event of loss of data), use SQL Server Management Studio Express in SQL Server 2005 Express Edition with SP2, which is a free download available at http://go.microsoft.com/fwlink/?LinkId=157721 .
    
    
  • To back up databases on Enterprise pool back-end servers and, in the event of database loss, to restore any of these databases, use SQL Server Management Studio in SQL Server 2008 and SQL Server 2005 with SP2. For details about installing SQL Server for Enterprise pools, see Install SQL Serverin the in the Deploying Office Communications Server 2007 R2 Enterprise Edition documentation.
    
    
  • To back up other Office Communications Server 2007 R2 databases (such as the databases used for Monitoring Server, Archiving Server, Group Chat Server, and Group Chat Compliance Server) and, in the event of database loss, to restore any of these databases, use SQL Server Management Studio in SQL Server 2008 and SQL Server 2005 with SP2.
    
    
  The appropriate SQL Server version should already be installed on each server that already hosts a database, as a result of the original deployment of each server on which a database resides.
  
  
• File system management tool(s) used by your organization to back up file shares and files, as well as to restore file shares and files.
