I paid for Sytos backup a number of times, but they did run off the 
rails mad with power.

Between them and SCO unix and general experiences concurrent with 
Stallman's as far as proprietary software was what put me off onto Open 
Source long in advance of Linux and GPL.  I don't agree with the social 
engineering aspects of Stallman, but I do not see that having hidden 
source makes any more sense than having a car you can't open the hood 
on.  The engineers and company will loose interest in a product and that 
sort of disposable attitude makes no sense.

Sytos had an excellent product for the time though as far as doing 
backups.  But the back end stuff as Chuck said, not so good.
