Hall Softwares

I asked this last night but now i’d like to know if anyone actually has a home network that backs up data on a dvd and what software you use. I have one, but i’d like to see if there’s a better one. Mine won’t allow for duplicates names,such as “documents and settings”. I’d really like to do the backup of all 3 of our pcs in 1 swoop. So anyone else backup a home network with dvd and what software do you use.
