I'm done with this crap, too. Installed the "new version" and still running 2 days later to back up 13gb. Even took my laptop to work and connected to our gigabit connection and still only seeing 400-500K upload speeds (same as at home). I suppose if the incremental function really worked then it would be OK but when it wants to do a full backup every single time this really isn't acceptable.
Idrive - don't bother with your "send us the ticket number" response...too little, too late. I've been down the path and ZERO response on my ticket weeks later.
