Need help burning/erasing DVDs from command line
I am trying to make a script that will automatically backup my home directory onto DVD. The only thing I have left to try and figure out is how to erase DVD+RW disks from the command line and then burn the ISO onto them. I tried:
$ cdrecord blank=all dev=0,0,0 speed=1
It started working, the drive got ready to start erasing, but in the end, all I got was:
cdrecord: Cannot blank disk, aborting.
I don't know if it is the setup I am using or if cdrecord just doesn't do DVDs, but I want to try and get my backup script done. Any help on a command line option to burn and erase DVD+RW's would be greatly appreciated.
