I recently got a Synology DS411j NAS. I have spent quite a while transferring everything to it from an external HD. I was finally ready to back it all up with Time Machine, but it turns out TM doesn't even see the NAS drive. I tried mounting it through the "connect to server" option in Finder, but the folder on the NAS with everything on it is greyed out. Oddly enough, TM gives me the option to exclude it from backups, but when I exclude it, it doesn't even show up on the list of exclusions. Unfortunately, every time I google any variation of Time Machine and NAS, I am inundated with "using your NAS for Time Machine." However, this is not what I want to do. I would like to have access to my NAS and back that up, along with my computer, to Time Machine. Can you guys help? Thanks in advance!
