	cpio -ivF cpio_file [file_to_restore ...]

the [ ] indication optional file name(s); you can list multiple files

do your full backup and when it's done, create a file so you know when
the last backup was:


	find / |cpio -ovF cpio_fullbackup
	touch /etc/lastbackup

next time you need to do an incremental, only backup files newer then
/etc/lastbackup (these will be the files that have changed).

	find / -newer /etc/lastbackup | cpio -ovF cpio_incremental

this should backup all files newer then /etc/lastbackup

to list files on the tape:

you could redirect this to a file and the more the file:

	cpio -tvF cpio_archive > tape.list

hope this helps.
