Check out rsync
. This command will synchronize any two machines, or any two directories
in one machine. It is a REALLY good way to accomplish incremental backups to a USB hard-drive
for example. It checks dates and sizes and only updates the new stuff. It
keeps your file trees intact and can recurse through directories. It is also blazingly
fast. I do not know whether DVD's are rewriteable more than once, but if they are, you could
probably use rsync with DVDs. I really recommend an external hard-drive though. That is a forever
backup solution and you don't have to track all those DVDs.
