Ok, I am looking for some ideas or input in case I have not thought of everything yet. Here is my situation: I have 2 computers at home, a desktop and a laptop. The laptop is my wife's and it is basically a fun/personal computer with some of her work stuff on it (teacher). I also have some of her work stuff on mine (desktop). Now I travel to and from my office with my desktop (27" Imac), I know crazy, but it works. I recently had a slight snafu with my Lightroom catalog and lost one of my latest projects, so here I am trying to better my setup. So currently, since the incident, I keep my main working Catalog with All my photos on a separate HD (30K photos). I back that up to a a 2nd slightly smaller separate HD. I also have an additional separate HD for just videos, but it's just about full. Finally I have a 4th separate HD which backs up just my computer and only the small "In Progress" catalog from light room.
Here is my process. Upload shoot into "In progress catalog" on computer. Process photos, move them to "main" separate HD for storage and Publish folders used for my website and web sharing. I then copy the processed photos to the 2nd back up separate HD, and then finally erase them from the computer.
Ok, hopefully this is making some sense. So I am now learning about mass storage, and want to make the right decision. I do most of my editing at my office and some at home, both of which are on the same desktop, so I am ok with maintaining the first portion of my process of keeping the "In Progress catalog" on the computer.
So my basic understanding is that the DAS may be a little better for my setup, but the NAS may be what I am looking for. Here is what I am thinking of a new setup. Basically I would use the Mass storage as 4-5 separate hard drives kind of like I am now, and probably not in a raid format. Let's say I go with a 4 drive setup. 1st drive will be my main working catalog with all my photos and publish folders. 2nd drive will be for storing and working with all my videos (not a big part of my life at this point). The 3rd drive will be an additional back up of both the first and second drives. And finally the 4th drive will be for my Time Machine backup of my computer (and In Progress Catalog) and my wife's laptop.
Ok, so hopefully this isn't too boring and making sense. So as it appears I will be mainly using the mass storage for back ups. I would like to if possible be able to access the information from my office, mainly to transfer the completed (in progress catalog) work to the "main catalog" on drive 1 so that I can publish it online. Also In case I want to work on some of the photos on the main catalog from the office that I have not copied to my computer.
Just looking for additional ideas, input, thoughts. I am hoping I have a decent basic idea here. I know it's a bit of overkill but hopefully it will last me several years and I can grow into it. One major question I have and am going to research is, "Can I connect my desktop directly to the NAS/Mass storage for a higher speed connection when I am at home, or does it only work through the Ethernet? I also have an Xbox, wireless printer, 2 tablets, and 2 phones in the house and if I can integrate them as well that would be cool. I am just not that quite knowledgable about this stuff, but I do learn easily.......
By the way, right now I am leaning towards the Synology NAS 415Play but am open to all ideas.
Thanks in advance for reading, and replying......Have a great day......Jake
