Software for Backing up across multiple cdroms.

[Clay Holladay]

What is the best software to use to automate backing up a large amount  
of data across multiple cdroms?  I have found some programs such as  
cdtar and scdbackup, but are there any programs considered to be  
reliable?  I could just try to divide the data into segments and do it  
manually but i'm wondering if there is an "industry standard" approach  
to this problem...
