I've donated and I will not hesitate to buy it either. It is good software and he deserves to be paid.

Likewise! Depend on CCC for regular interval backups using for overall system (startup), Documents, Movies, Pictures and Virtual (Windows) machines.
I use Retrospect for my "Primary Backup". Actually, CCC and Retro have their uses in my plan. We have three machines and use both independent of each other for full back ups so there is redundant backup. At no time is any machine completely vulnerable.
Scattering my backup among eight drives (my family of JBODs), in two groups - FW800, four drive set, and a group of four USB drives (PATA/SATA bare drives in a Startech drive slotted, sort-of hot swappable carrier) – all running on a recent MacMini Server, provides flexibility and sufficient space for all backups and other file sharing uses. There have been occasional drive failures and fairly easy recoveries over the past 10 years, but it's something that works. I am next planning a move of all this hardware when we sell our house. That should prove interesting.
I found something that works fine, for me in my networked environment (for each app). Planning on sticking with it. Having two different apps running backup with CCC in a distributed environment seems to work well as a backup plan component. Certainly worth the price.
The documentation on what's running on what machine was a little cumbersome to build (one of CCC's drawbacks is that any backup up of a single machine is best done from the machine itself, there is no server version). We developed a method to do it that's different for each app and that reliably works.
Retro is more suited for server use.
