2 Backups on a CD-R

[Nick]

Hello Barry

I have a 700 MB CD-R that has 150 MB of data from a previous backup job. I tried to use this CD-R to add another (different) backup job but AISBackup said that this CD-R can not be used. I try to minimize the number of CD-R I use and I find it strange that I can not use the remaining space on this CD-R. Am I doing something wrong?
Thank you

When using the integrated CD Mastering system each backup must use its own set of CD’s. This is because each backup uses the volume number of the CD to keep track of files, this is usually different for each backup job.
