Don't I look happy in this photo? You know why? It's because I figured out how to manage my thousands of photo files. After 1 and 3/4 365 projects, I learned that hardrives don't have unlimited space. Not only do you have your 365 photos, but you have the photos you took alongside those photos. Say you went on a week long trip. You have 7 photos at the very least (for the sole purpose of being in the 365), but you probably had to pick those photos from a large library of photos you took on your trip. Those photos add up fast, and chances are your laptop hardrive isn't going to be able to handle a year of that.
A while back, I wrote a piece on my personal backing up and storage system. Storage management is extremely important to being a photographer or just taking a ton of photos. A thousand things could destroy or erase your files, and you need to protect them. In my mind, there are 3 basic storage avenues you need to keep your photos safe. There's no end-all perfect way to store your files, so you need back up your backups.
1. External hardrive(s): You need a backup for your main machine so your ongoing projects are safe. Not only that, but you need another external hardrive to hold the things you can't fit on your computer, also, a backup for that. This is pretty basic, and you can find a 500GB backup for pretty cheap these days.
2. Cloud storage: Dropbox, Google Drive, or Joe's Cloud Service, you can't just trust yourself to protect your files. Just think, all 4 of your hardrives could be destroyed in a flood or fire, but if you keep it in the almighty cloud, they are safe from the elements.
3. Syncing: This isn't essential, but it's useful. (It will also be kicked up a notch with Apple's Continuity feature in the new OSX update) How do you access your files? Is it convenient or painful? How do you get to your 365 when you need to post them on Instagram? With cloud storage, you get the added advantage of accessing your files through a number of devices, but it also goes the other way around. Say I took a 365 photo with my iPhone, I can walk over to my laptop and access it seamlessly without wires or any of that iTunes crap. It also backs up your photos from your phone or tablet.
Your system is flawless and your files are syncing perfectly, you are in the homestretch of your project, what now? When your 365 ends, do you just toss your folder aside to make room for the next one? The 365 is an archive of an entire year of your life, it doesn't deserve to sit in the depths of your hardrive without being touched or looked at. I haven't gotten this one perfect yet, but I think this project deserves more than to be digitally buried in your computer's backyard. Make a book, print them out, bring them into the real world. For my first project, I printed out 5x7 prints of each photo and hung them on a wall, for the 365 Reloaded, I'm making a book. Some pictures may not be as great as others, and you may not be proud of all of them, but they are important nonetheless. Once you'll see your body of work all together, you'll know what to do. No matter what, these photos will mean something to you, and maybe even your friends and family too. Don't waste them.
