Linux way of selctive backups

Sometimes we have a choice of only backing up some of the selected files from an
application or some other very crucial files. Below is how I do it in a real quick way:

cat >> /etc/bkup.conf
/usr/local/apache/conf/httpd.conf
/usr/local/apache/conf/httpd.global.conf
/usr/local/apache/conf/httpd.mod_jk.conf
/usr/local/apache/conf/vhosts/*
/usr/local/apache/conf/httpd.vhosts.include.conf
/usr/local/apache/conf/httpd.ssl.conf
EOF

Then I run tar command with -T flag pointing to the file which contains
the list. In my case it is /etc/bkup.conf

tar -cjf bkup-WebConfig-`date +%Y-%m-%d`.tar.bz2 -T /etc/bkup.conf

And you have your selective backup ready!
