Hi all, I have a Macbook pro, I'm a photographer and I've purchased 2x external 4TB Thunderbolt G drives to relocate my all of my photos (around 1TB) to. The plan was to copy all of the files on "drive 1" and then manually copy the day/week across onto "drive 2" on a regular basis so they would be a duplicate of each other as I had been advised that time machine would not be suitable. However, I have looked into carbon copy cloner which seems like it would be a better option from manual. From what I have read; I can automatically schedule the back ups plus if I make changes to a set of images on "drive 1" then that will be reflected on "Drive 2" when it backs up. Not sure if you need to know but: MacBook Pro 15-inch, Late 2011 Memory 8 GB 1067 MHz DDR3 Software Mac OS X Lion 10.7.5 (11G63b) Replaced original HD with a 1tb HybridSSD and replaced optical drive with original 500gb HD. Advice would be great fully received as I am quickly running out of room! Many thanks.
