Mozy, the cloud-based backup service for both PC's and Macs has just released version 2.0 of its Mozy for Mac software. Lifehacker reports that while most users won't notice anything other than the shiny new Mac-native appearance, Mozy also added a new query builder to make creating advanced backup rules easier, improved performance and stability, increased backup speed, and added an easy on/off switch for setting up automatic backups. In other words, they have attempted to make it even simpler to use than it already was.
