Sarge - how to write a filesystem backup directory to a DVD ?
Having gotten a new internal DVD burner, I'd like to know the best way to burn
a directory of files to a DVD for system backup. (Also, I'd rather burn the
DVD using a command at the BASH prompt instead of from a GUI.) The capacity
of the DVD is 8gb, write speed is 16x, and the size of the directory to be
burned to the DVD is about 7gb so there should be plenty of space.
I've installed dvd+rw-tools from the Sarge CD's.
I'm a little confused - should the input to "growisofs" be the directory that
is to be burned to the DVD, or should an .iso be created first, and that in
turn burned to the DVD, as is done with CD's ?
I've seen references to "formatting" or "initializing" DVD's on a few websites
but don't know if that's really necessary.
A URL with a step by step sequence of how to do this or troubleshoot this
would be appreciated.
