Topic: Verify burned DVD Backup

[psoren]

Hi all,

I have just started using a backup routine based on this script:

Using the MD5 sum for verifying the backup after the burning, is from my understanding not reliable, So my question is: Is there an easy way to compare the data written on the DVD to the contents of the ISO?

Would it maybe be possible to compare the TAR files MD5sum using scripts, and how would that look?

I need this backup to go on a DVD every month, and it is not a part of my normal backup routines. It is an online backup from another server to my server using rsync. And we want just that online part to go on the DVD, but we also want to make sure it's there and valid.

Any suggestions?
