When was the last time you backed up your computer? It has been a while for me too! I am the WORST at remembering it! That is why I was excited to review Carbonite!
The best part? You can try it for FREE for 15 days-- you do not have to enter a credit card or anything like that. It is just free! After the free trial, it is only $59.99 a year (you can access higher plans as well). Check them out at: http://www.carbonite.com/
