Hello, I have two Synology NAS - DS414 - DS214 + I setup a folder on DS414 read / write copy of the key. The DS214 + I am sharing with the key. If I add, modify, delete a file on the DS414 is ok. It is the syncho the DS214 + but if I make a change on the DS214 + => Nothing no syncho on the DS414. I forget what? what is my mistake? Thank you for your advice. (Sorry google translation)
