Most I dont care about but, the ogg, mpg, mpeg, avi and mp3 - I do. Im
not sure why these would be excluded. I mean, you obviously want to
backup all your movies and music. Why would it exclude it?

"It" did not exclude them. The programmer who set the default
configuration did. Why? dunno.

easy enough to copy that to exludes.back and edit it so it does not
pass over media files.
