This is the one I basically followed - I read both that one and the freebsddiary one. I decided to reinstall the server though, because I was any way going to reinstall world and lots of packages were outdated as well.

Luckily I have a small UPS which should provide five to ten minutes of full power. In Finland the power cuts are quite rare and usually measured in mere seconds than minutes, so it's sufficient most of the time and if not, apcupsd shuts the server down after few minutes if something bigger happens. -- Henry Karpatskij http://ripe.net/fcgi-bin/whois?searchtext=HK1203-RIPE
