Hi Marc, everything works fine. I have recently installed BTSync from the SynoCommunity and until now the result is excellent. It was very easy to define the new repository for the packages, and then install it is a newbie action. Once the app is in both sides it begin to sync perfectly. I need to sync around 400 GB so let´s see how it performs. Thank you very much. PS: If you are looking forward a NAS, I highly recommend you a Synology. I have it for 2 years and I am very happy with it. And as you can see it has support from the community for such great things as this.
