I'm getting a new iMac to replace my MBA. My wife has a mid-2012 MBA and we are fully on the Apple platform with iPads, iPhones, Time Capsule, and Apple TV. I've done a very poor job at managing all of the photos and videos that are kept on our devices. Some have also found their way into iCloud which I need to reel in. With that in mind, I'm hoping that I can use the new iMac as a central "hub" to create some kind of photo/video data mart. I prefer to keep my family photos and videos out of the cloud. With that in mind, I'd like to keep everything local. My plan is to continue using the Time Capsule as the "end of the road" back up as well as a mix of periodic, ad hoc hard drive back ups that travel with me and sit at friends houses. However, where I get hung up is the desire my wife has to access the family iPhoto and iMovie library. She's used up all the space on her MBA and doesn't like the idea of me moving data from her machine to a hard drive. She gets that we need to free up space, but she doesn't like the not having photos of our kids from three years ago at her fingertips. With that in mind, my plan with the new iMac is to put the iPhoto and iMovie library into a folder and share it with her mac over our network. This would become the first point of upload as well as serve as a data mart. I would back this folder up to Time Capsule as well as pull periodic back ups to my hard drives. I could also share this folder out to the two apple TVs and I assume to our devices like iPhone and iPad. The only downside I see to this approach is that the iMac would have to remain "on" all the time, or at least in sleep mode... correct? So if I've got the machine in sleep mode, and my wife pulls out her MBA and hits the shared folder, will that wake the machine up? Is it 'ok' to keep a Mac running this way? What are the other alternatives? Basically I want to put all of our photos and movies in one folder and have it serve as the single point of entry and access.
