After some reading and help from these forums, I've decided on a storage and backup setup for my 13" 2014 MBPr, which serves as my main computer. I have a 245Gb internal SSD on the MBPr, which I plan to use to keep my programs, school and personal files (MS Office type stuff on) and Lightroom catalog files on. I may or may not also keep my music on the laptop (about 70 Gb). I'm looking at picking up a 4Tb Thunderbolt Duo (DAS) as my storage drive for Movies, and my Photographs and using it in RAID 0 to allow good speed when working in Lightroom. (NAS isn't really an option for me atm due to not having a Gigabit router). Lastly, I need to backup the RAID 0 and the MBPr of course. This is where I have some questions: 1) What would be the best way/process to back up the RAID 0 and my MBPr for my uses? (ex: Could I use TimeMachine to back up both to one single, larger capacity external drive, like a My Book Studio, or do I need to do something else?) 2) Is Time Machine the best thing to use to backup the RAID 0 and the MBPr? I've seen lots of people mention CCC, but I really don't know the difference here. I apologize if this is a bit pedantic, I'm not overly knowledgeable on this stuff (yet!). Appreciate the help, and any other tips for my situation!
