What are some of the operating system compatibility aspects to consider when using Backup Exec 11.x, 12.x and 2010 R1/R2/R3 with a Network Attached Storage (NAS) appliance when the NDMP agent is not in use?


The NAS operating system determines the level of protection that Backup Exec (tm) for Windows Servers can provide to the device. It also determines if the device can be used as Backup-to-Disk (B2D) storage media.
I. NAS Devices using Windows 2003 or Windows 2003 Operating Systems

  • The NAS devices are seen as remote Windows 2000 or Windows 2003 Servers. A Remote Agent for Windows Server (RAWS) and a RAWS license will be required.
  • After the installation of RAWS on the NAS device some of the native backup options can be used during backups with the following exception:
    • Backup Exec Intelligent Disaster Recovery (IDR) option
    • Backup exec Open File Option (OFO)
  • Windows based NAS Devices can be used as a B2D storage location.                     

Note: Be sure to use a duplicate backup set job to backup B2D data stored on a NAS device. For more information about Duplicate Backup Set job please refer to    

II. NAS Devices using Operating Systems that 'Emulate' Windows 2000 or Windows 2003 Operating Systems

  • The NAS devices that are 'emulating' a Windows 2000 or Windows 2003 Server permits the file system used for data storage. Backup Exec Remote Agent for Windows would not be able to be installed on such devices though files and directories can be backed up as ‘User-defined shares,’ from the Backup Exec for Windows Server itself.
  • The following Backup Exec options cannot be used:
    • Backup Exec Intelligent Disaster Recovery (IDR) option
    • Backup exec Open File Option (OFO)
  • If a NAS Device is emulating Windows please confer with the NAS manufacturer for assistance before creating backup to disk (B2D) folders on the NAS Device.

Note: In Backup Exec 12.5 and earlier, a RAWS License is not required to back up these systems via User-defined Shares. The backup job log will indicate a failed backup because of the Remote Agent not being present and a licensing error. Confirm that the amount of data backed up compares with what is physically on the share and run test restores to validate the integrity of the data that was backed up. Starting with Backup Exec 2010, at least one RAWS license is required to back up NAS systems.


III. NAS Devices using or Emulating other Operating Systems

  •  NAS Devices that are not using or emulating a Windows 2000/2003 Operating System may only be able to backup its CIFS shares.

Note: NetWare Servers cannot be used as a Backup-to-Disk (B2D) Target because of file system rights issues.
