I know that if i want to have a fully backup i need 3 things.

1) Mysql dump

2) copy of config.php

3)and copy of .rrd folder.

My question is: Do it's enough to have first two things: MYSQL dump and copy of config.php ? Because old traffic data (.rrd) is not so critical as loosing all the rules/alerts of Observium (and weathermap which is on other directory)
