You can restore the system seperately from /users, because cpio accepts a
list of files/directories to restore.
tcio -i /dev/backupdevice | cpio -icdmuvx .profile SYSBCKUP bin dev etc hp-ux lib system usr

Alternatively, you could split the backups into system and users backups. 
Change your /etc/backup:

	backupdirs=""
	for arg in $*
	do
		case $arg in
		-archive)	aflag=""	# all files.
				aecho="archive"
				;;
		-fsck)		fflag="yes"
				;;
		-users)		backupdirs="$backupdirs users"
				;;
		-system)	backupdirs="$backupdirs .profile SYSBCKUP bin dev etc hp-ux lib system usr"
				;;
		*)		echo "usage: $0 [-archive] [-users] [-system ] [-fsck]"
				exit 1
				;;
		esac
	done
