I have recently installed Nagios 3.2 complete with NDOutils, Nagvis and using MySQL as database. I am looking for ideas for backup of the whole system. I can tar up the ancillary stuff but with all the config stuff in MySQL I need a good scheme for backing these up nightly. I can use mysqldump and log into each database and dump to a file, but not sure if his is sufficient to give a good DR backup.
Does anyone have any ideas on backup of Nagios and the associated database and config files
Thanks
use a mysql replica 
or stop the nagios service and make backup of the tables. Depends if you can afford stopping nagios for a couple of minutes during the night.
