Creating file backups to DVD
I'm trying to set up a file server on my home network. And, I want a way to backup selected files for a nightly backup (just in case the disk dies). Can this be done with a DVD writer? If so, are there any particular brands of DVD writers that just aren't compatible with Redhat Fedora Core 2? Also, can this kind of backup be scheduled in cron? If so, what would the command line be?
