I recently installed a Synology DiskStation on my network. I mounted it from an Ubuntu 12.04.1 computer with the Browse Network button in Nautilus 3.4.2. It shows up as afp://randall@DiskStation.local/photo/ in Nautilus.
So far, so good. I then uploaded a lot of photos to it, all with modifications times covering several months. When I looked at the directory of photos on the DiskStation, they all had modification times for the moment they were copied, not the modification times on the source computer. So much for sorting them by date on the DiskStation.
Is there a way to re-copy the files but have their modification date be preserved? Perhaps I mounted the DiskStation the wrong way. Perhaps Nautilus was the wrong tool to use. Any suggestions?
BTW, I have moved gigabytes of photos to a different NAS (Plextor PX-EH) over SMB/CIFS from Ubuntu 10.04, 10.10, 11.04, and 11.10 with modification times fully preserved. The problem must be with the Synology or some Ubuntu 12.04 software.
