The DocRetriever Agent software must be installed on the front-end web server for each SharePoint server farm where you want to recover content.
Optionally, if you have more than one front-end web server, you can install the DocRetriever Agent on each SharePoint server. For example, if you have a substantial amount of traffic on a primary front-end web server, you may wish to install the DocRetriever Agent on another machine to relieve pressure on the primary web server.
To restore SharePoint data, the SharePoint administrator must also install the DocRetriever Console on the machine to be used to browse SharePoint offline databases. This machine must have a version of SQL Server 2005, 2008, 2008 R2, 2012 or 2014 installed. Microsoft SQL Server Express, Standard, and Enterprise editions are supported. If using SQL Server Express, SharePoint databases must be smaller than 4 GB. To use the content search function of DocRetriever, Express version installed must be Microsoft SQL Server Express with Advanced Services.
You install both the DocRetriever Agent and the Console by using a single installation wizard. Upon launching the wizard, you can select the specific components you want to install.
Complete the steps in this procedure to install DocRetriever.
