I am using mkisofs to create ISO image for backup. I was just wondering if there is a way to restrict the iso image size so that when you try to image a directory which contains files with sizes over 650MB, it would know where to stop so that you actually get an image of 650MB.
For example, lets say I want to backup my entire /home directory. The folder is about 900MB. I just run
mkisofs -o myhomebak.iso /home
Is there anything to keep track of the current iso file size so that when it hits 650, it can either create another iso for the remaining 250MB or prompt you where it left off. I don't want to use any gui tool for this since this may be part of a shell script. Thanks.
