Despite having large hard drives in our servers, network attached storage system, and external fire wire drives we are running out of space. Therefore, we will no longer be backing up audio and video files. Audio and video files are extremely large files and best burned to optical media for storage off the network.

File type by extension no longer backed up (this list is not comprehensive)
