How about:
work ~ # cat backup.sh
#!/bin/bash
mount /dev/sdb8 /y
rsync -av /bin /etc /lib32 /lib64 /opt /root /sbin /usr /var /y/bkp-sys/ \
--exclude-from 'exclude'
umount /y
echo "done"
work ~ # cat exclude
/usr/local/
/usr/portage/
/usr/src/
/var/empty/
/var/log/emerge-logs/
/var/tmp/
You can rsync multiple directories, just put dem down there one after
another, the last on is the target.
You should also consider setting the --delete flag (deletes file in
backup when deleted on your root filesystem and --delete-excluded which
will delete the files you have excluded in your backup.
I also exclude /var/cache and /var/run
