Backup to DVD drive problem



I’m trying to do a system backup to a DVD+RW disc on my laptop using a Sony DVD+RW DW-Q58A

I’m getting the following message…

The back up file could not be used “D:/backup.bkf”
Please ensure it is a valid path, and that you have sufficient access

Can anyone shed any light on what’s going on?

Many thanks


Did you ever get this to work?


Thanks for asking. I bought an external hard drive in the end. I suspect I should have downloaded some DVD burning software.
