Where do uploaded files go (photos, videos etc.)?

I want to save all my members uploaded photos, music and video, in case something happens. Like profile photos for instance. Where can I find them all so I can store them on to external hard drives or somewhere?

mem pics = /media/images/profile

mem movies  = /ray/modules/movie/files

mem music = /ray/modules/music/files  & /ray/modules/mp3/files

safe to just save a copy of your entire /media folder

thanks alot! that was easy
