Another tool similar to to dvdbackup is vobcopy.

But you have to remember two things:
1) dvdbackup or vobcopy make a backup of the video content
of the DVD but they do not backup other files present outside 
the directory VIDEO_TS
2) If you make a backup of a DVD9, you will not be able to burn
it on a non dual-layer dvd media.

With encode2mpeg (http://encode2mpeg/sf/net)
you can backup easily the full content of a DVD with just the following command:

encode2mpeg -o DISK -cache /var/tmp/cache /media/cdrecorder -savecache -removecache -cacheonly

You have also the option to backup a DVD9 on two
single layer DVD and be able to use the 2 backup DVD
on a PC.
