Mar 11, 2015 5:32 PM in response to Nielby AddNic,That was quick . I have a mid-2012 MacBook Pro, 2.3 GHz Intel Core i7, 4 GB 1600 MHz DDR3 with Intel HD Graphics 4000 1024 MB, and I want to back up the whole thing. My system came under attack recently and I want to make sure I can go back if malware ever completely tries to destroy my life. haha Should I get a terrabyte? I have an external lacie hd, but i think it's only 114 GB. Probably not enough, eh?

Mar 11, 2015 7:18 PM in response to AddNicby LaPastenague,If the MBP has 500GB disk then a 1TB drive is about the min you should buy.. The cost per GB goes down as the disk size goes up.. so larger disks are better value than smaller ones.. I would not even bother with disks smaller than 2TB now.. unless you are after small 2.5" disks.. For most people 3 or 4TB are really great and cheap.. you can then partition it and use a disk image not just Time Machine.. make a bootable clone of your MBP and recovery is as simple as boot from USB .. back to your previous setup.. recovery from TM is a process that takes many hours or days.
