Is it possible and/or a good idea to store all of my photos on an external hard drive connected via usb directly to my wifi router? My reasoning for wanting to do this is: 1. I have a desktop pc that is not really powerful enough for editing but I still use for viewing and uploading photos. 2. I have laptop that I use for editing because it has an i7 2.2ghz with 8gb ram. However I do not want to store photos on my laptop because it doesn't have enough storage and it will not always be powered on. 3. I want my photos available regardless of whether the desktop is on or not. (will mostly be on unless rebooting for updates). If I go this route, what is the best way to backup my photos? I would like for the network attached external hard drive to be automatically backed up to the internal drive on my desktop computer. Any thoughts?
