It depends on how you built the backup. If you used tat to backup the files, before burning them, then the -d option of tar will let you compair the files in the archive to the origionals.Hello Mikkel,

You need to be sure, if you are going to rely on this. Check the permissions of the files. If necessary try to open them as root. If you can't even do that the backup is pretty useless, I would have thought.

Agree totally! BUT - from the recent messages, it appears that there is NO WAY to verify a just-burned CD/DVD to make sure the data is the same and can be read OK. Still looking......
For a "quick, cheap, and dirty" check of the files, I find something like
for i in /mnt/dvd/* ; do echo Reading $i ; cat "$i" > /dev/null ; done
works well. It will tell you if the files are readable. It will not tell you if the files match the origional ones. It also doesn't follow directories. Do not forget the quotes around $i in the cat command, or you will get errors if you have any file names with spaces in them.
