Tru64 doesn't have any support for packet mode (UDF) writing on CDRW drives. The cdrecord command does permit multi-session recording, but with an overhead of ~30MB per each additional session.
I decided the easier method was to use vdump/vrestore for incremental backups, and create a wrapper for so that the saveset can be broken into chunks of <=650MB. Each chunk can then be written to a standard CDRW via mkisofs/cdrecord.
This also allows full backups to span more than one CDRW disk, which is good enough for our needs.
