Hello All I copied all the Files of one file server to a brand New ReadyNAS 104 (about 3 Terabytes of files). After that I tried several times to let it finish sync (it only compares the Files, as I see it, there are no data copied). It always starts very fast, but after a while it takes forever to sync as more and more files are inside the dataset.. any thoughts on that? The idea is that the ReadyNAS creates a exact Copy of my Business Files at home, so I have an automated Offside Backup. The ReadyNAS has only 512 MB RAM. I suspect, that it cannot cope with a Database for 120'000 Files in 3 Terabyte of date.. could that be the reason? Any other ideas? regards, Urs
