This is something that I have had since I become freelance. I have to say it is good to know that I have all my photos in one place. So I do not have to worry about how many photos on my Mac or PC at any one time. I have set up a filing system for importing my photos so it is easyier to find. As I might have to look for photos that I have already done and would like to change. I have to work out when I shot the images just to find them.
This is more true with all the landscape photos that I have taken over last year. I have added all the photos from my photo hard drive to here which sadly is starting to run out of space but hopefully it will be a while till it dose feels up fully. It is easy to get on there just it will take some time to update it.
This is the one thing I am not a fan off is all the moving around I will have to do when it comes to retouching and my photos. I will need to start the move soon as I would like to have them in different places.
One thing about backing up which I should but do not do. Is to have things in other locations than where I am. This is not great as I should be doing this. Just I do not have the money right know, for it.
I would say if you are a photographer you should have your own home server as this will help out with file handling and working on photos on that you shot years ago.
