Hi:
How do I get the image of a given DVD? I mean, the DVD, recorded by me, contains a certain ISO9660 image in it. How do I transfer it to the hard. All it contains is data. Any hintwill be welcome.

You can do either:

Code:

dd if=/dev/dvdrw of=image.iso

Code:

cat /dev/dvdrw > image.iso

If you mean that there is a file 'yourimage.iso' on the DVD, then:
Mount the DVD as would normally to say '/mnt/dvd'.
Then 'mount -t iso9660 /mnt/dvd/yourimage.iso /mnt/tmp' should allow you to access the files under /mnt/tmp.

In no way. I think H_TeXMeX_H got the idea. I backed up a subtree from the hard into a CD. Now the subtree on the hard has grown up and is bigger than a CD capacity. So, DVD. And I must merge the old subtree with the new one. Got it?

So you want to bring back any data from the CD that is not present or has not been superseded into the tree on the hard disk.
I would use 'rsync -u /path/to/CD/ path/to/tree/'

Thank you so much, allend, for you suggestion. I'm looking forward to make it work. Regards.
