JIMSTRONG I've used ChronoSync for 18 months now and have been very pleased with it - I do several scheduled backups overnight from my G4 Mac to a PC over a small network, with a total backup size of around 55 Gigabytes.
I recently picked up what turned out to be a really strange error deep in the operating systems, where a couple of files would not archive. Given that this was quite a rare occurrence, EconTechnologies couldn't have been more helpful in working with me over several weeks to identify the problem and implement a solution. So this is just to say "Thanks Guys, great product and excellent support!"
