No worries dude.  Everything is backed up every 30 minutes on DEDICATEDPOOL.COM.  I got so upset at all these bad pools that I finally had to put one up to properly mine without interruption.  Mine with us and we'll make sure you're taken care of.

However you should always set an auto transfer of at around 100-200 coins.  Don't let them pile up.  Get a wallet on your PC or send them to an exchange!
