Very good. I haven't tested the load (cpu, network, disk) on the hardware yet, but it's working flawlessly.
I have been testing it quite some weeks now. I have set it up to automatically sync c:\documents and settings\ to a network drive (samba/cfs share). Realtime sync. Autostart as a service. 3 Backup changes.
My wife doesn't even notice all of her documents on her pc are automatically synchronised to a network share
At the moment Dsyncronise.exe uses 2284KB memory and 0% cpu time.
Memory use gradually rises after some actions (now 2404 KB) , but cpu isn't hardly affected. (still 0%).
Gonna keep using it. It's an excellent no pain no hassle form of backup, especially for people who don't want to think about backups
