Recently I mentioned that I was looking for some good software to backup my iMac to my networked hard drive. After looking through a list of available solutions, I finally found one that seems to work: ChronoSync. It does everything I need: one-way synchronized backup, automatic scheduling, error logging, and automatic mounting of the network drive. It even sends me an email when there's an error!
You can download a trial version from Econ's website, but the trial version is really annoying. It displays a splash screen that requires you to click on it, and it only lets you make one backup before having to restart the program. This made it impossible to adequately test it out. Fortunately, Econ allows you to request a temporary license; I did, and now I can test it fully functional for 30 days. So far, so good. Barring something unexpected, I'm going to be buying this backup software.
