Be very careful as GNU tar is buggy and does not always like to read
continuation volumes from multi volume archives. This is extremely nasty as
you will realize the problem once it is too late.
GNU tar also does not support to archive all meta data from Linux.
I recommend to use star. Star implementes reliable multi volume support and
archives all meta data that is available on Linux. Only a reliable multi volume
support inside the archiver allows you to read back archives starting past
volume#1.
Note that star also implements a nice true incremental backup feature that
does not need additional data while creating backups. There is a database
for old and new inode numbers in incremental restore mode.
Check the star man page for examples on backups and incremental backups.
Use tsize=4200k -multivol to tell star to write archives with multi volume
information that split files across volumes.
Use mkisofs to create a ISO filesystem (hve a look at the -stream-media-size
option.
Use cdrecord to write the ISO file to DVD.
