To allow end users to search and retrieve their own files and email, you must first configure Backup Exec Retrieve. During the configuration, you point to repositories of user data that are available in the enterprise. These repositories are known as data sources.These data sources contain backup copies of files or archives of files and email messages.
For example, you can add a Backup Exec media server on which the Archiving Option is installed, Continuous Protection Servers, or Backup Exec System Recovery Manager servers. You add these various data sources to Backup Exec Retrieve which in turn provide retrieval data to end users.
See Adding a data source.
