When it comes to backup products for the Apple Mac, you only really get three options: EMC's Retrospect, Archiware's PresStore and BakBone's Netvault. I have spent the last couple of months evaluating this software for use in an enterprise scale environment and have chosen PresStore as my backup product of choice. Why? Well configuration can be complicated and the licenses can be expensive, but the performance and reliablity of this software is very impressive indeed. Although I found the configuration to be unusually complicated and convoluted in comparison to Retrospect and Netvault (it is a steep learning curve), once it is setup the software is easy to use and incredibly powerful.
