In light of a near crash and loss of data this week with my 2010 MBP my interest has been rejuvenated in creating a system of complimentary Apple products to share data capacity as well as backup a few crucial files. On my current MBP this is where I stand; As you can see, iTunes takes up most of the space as I'm sure it does for many others. Over the past few days I've mentally drawn up this plan which I'd like to get opinions and suggestions on. Beginning, the MBP would be sold and replaced with a 13" 2014 MBA with a 256GB drive and 8GB of ram. To offset the reduced storage space, would upgrade my current AirPort Extreme with the 3TB AirPort Time Capsule. For Time Machine purposes I'd partition 500GB of of the internal drive. The remaining 2.5TB I'd partition for iTunes library use as there are many movie purchases I've yet to download (purchased 100+/-). I have very few truly critical files, so what I do have I was going to make a secondary backup utilizing a Micro SD Card in a tray from The MiniDrive. To free up additional space, decided I could also maintain my photo library within iCloud Drive once it goes live. My financial documents; Excel, could be copied using Office 365 Personal. Are my bases covered or do I have a hole which I cannot see? I know I may need to backup the iTunes library but most can be re downloaded so at this time it's merely and inconvenience rather than catastrophic. To round out the system; will replace our iPhone 5's with 6's (Me: 32GB, Hers: 128GB if confirmed). Same with our iPad minis. All in all, trying to find a streamlined setup with data redundancy, while logically sharing data across the board to make best use of the SSD drive size, and minimizing the data streamed to her iPhone and iPad while on cellular. What would you change?
