Essential for safe data habits and very flexible.

Sync Folders Pro is well worth the money for making backing up data and synchronizing data across various platforms simple and reliable. It is easily able to synchronize folders between my local hard drive, networked Airport Disk, Drop Box and Transporter Sync volumes. This allows me to set up data redundancy between these platforms that allow access remotely. While you can supposedly do this through Terminal commands and Applescript, I found this to be a much simpler and more reliable way to set up recurring and scheduled synchronizations across these various platforms. It is also helpful in consolidating data that has been warehoused in various volumes to syncronize content so that a copy of everything is preserved in the location of your choice. The Sync modes take a little bit of figuring out at first, but the pro version allows significant control over what to copy and in which directions.
