Mapped network drives cannot be backed up or restored with Backup Exec for Windows Servers.
Remote Agent for Windows Servers (RAWS) is required to be installed on the remote system and the serial number for the remote agent should be registered on the Backup Exec server. The Remote Agent for Windows Servers (RAWS) license is not required for workstation operating systems for versions up to Windows XP. Windows Vista and onwards requires a License key, however the component needs to be installed on the workstation.
Remote Agent not only exposes all the Windows features for Backup Exec to back it up, but also increases throughput during the backup.
