I'm trying to use Sync 2.0 to keep backup copies of 5TB of files that will eventually be offsite. When I link a new device, it takes 4-5 days for sync to transfer all of that data from the original device to the new device. Sync is pretty fast, but still only ~ 20% of the speed I get doing a plain file copy. I'd much rather have all the files on the new device and just have sync index them and make sure they are the same as the first device. But, every attempt I've tried has resulted in sync wanting to create new folders (with (1) after them) and re-copy EVERY file over again. It's a real issue, and one that will probably prevent me from using Sync if I can't resolve. The question, then, is: How can I link a new device which already has all (or most) of the files that the original device has, without forcing them to be re-copied? Thanks!
