I've got a MacPro and MBP that are essentially set up with the same programs. I'll work on the MP most of the day but in the evenings when the kids get home or on the weekends I'll often switch to the laptop. The issue is that I need files that I work with on the main computer available to use on the laptop. I think the simple answer is to attach a shared drive to my Time Capsule, but here's the complicating problem...occasionally, I take my laptop outside my home network. I'm worried that I might forget to copy a needed file from the NAS to my laptop. I suppose I could use cloud storage or make the NAS available to the outside work, but I've been in situations with no WiFi or very slow connections. Unfortunately, in this case I'm still hanging on to my unlimited data plan for my iPhone which means I can't tether either What I think would be ideal is for my programs to simultaneously save any file I'm working on, on both my local HDD and the NAS which I think would always insure I'm working on the most recent document while also making sure I don't run out of the house with my laptop and forget a needed file. Thoughts on a solution?
