What's on my computer, how it got there and how to use it

Installation of cdbkup done with ./configure --with-snardir=/mnt/sbackup --with-dumpgrp=root. /mnt/sbackup is a 10 GB partition I created for use with scdbackup. It’s a staging area for burning DVDs. the dumpgrp was necessary because cdbkup used a default group of operator, that I don’t have on my system.
The autodetect feature couldn’t tell how big my DVD was, so it used the default of 650 MB. Then after the message Collecting input data... it just exited.
I’ve been backing up my file systems to Travan TR-4 tape with a Seagate TapeStor SCSI unit for a few years now. Last week I was running low on tapes and a Froogle for them returned prices from $20 – $30 each! Given that these tapes hold 4 GB uncompressed and DVDs hold 4.7 GB, and media are a couple bucks at most, it was time to retire the tape drive.
So I started to look for a program that would back up to DVD. My first try was scdbackup. The system backup worked just fine. Then I tried to create a level 0 back up (to allow incremental back ups) using sdvdbackup_sys -conf_dir /root/backup_system -level -create_configuration. This hung during generating -content_list_adr. After running some tests creating a level 0 back up, it seems that scdbackup will fail collision detection if it is given an empty directory (such as /opt) to back up and it hangs during creation of content_list_adr if told to back up /dev.
