The headline of this utiarticle caught my eye. The contents even more so.

I've been using Retrospect for 12 years now as a backup solution for my Macs (and PCs), and I've worked with and spoken with the guys at Dantz, as it once was, a number of times. Once in possible preparation for a backup on enterprise backup using the software.

The lack of support, and more importantly on going releases, on the Mac platform is something of a concern. Retrospect had more or less got the backup, and particularly enterprise backup, market cornered. Why would you let your company lose that kind of market?
