When SAV for NAS is integrated with a NAS device the NAS sends files to SAV for NAS over the network.  Doing this for large files may cause performance issues on the network or on the NAS device.  


Configure the NAS device with filename extension exclusions.  These extensions include known file-types that are significant in size. 

SAV for NAS also has the ability to limit the files scanned based on size.  See the following article for details: Excluding large files from scanning to improve scan and network performance in Scan Engine 5.2.5 and later.
