Hello everyone, I tried to seach but got lost in very descriptive explanations of what I don't know about much. I'm a recent Mac convert from windows, and have noticed I'm starting to run out of space on my MBP Retina Hard Drive (256GB). So I purchased a 1TB USB 3.0 7200rpm Hard Drive http://www.bhphotovideo.com/c/product/891239-REG/Hitachi_0s03559_1TB_2_5_External_Drive.html Now I'm debating my backup strategy and have a few questions hope you all can help... 1) I know I need to reformat the drive once I get it, but not sure how or to what to. 2) If I do a full backup style (Time Machine?), can I clear up the space on MBP after it has backed up? Since my concern is running out of space on my MBP in future, my thought is to keep my videos/music/large files on external drive and delete from MBP to keep space free. But full system backup would be nice....both possible? 3) Or is a simple manual file backup best since I can migrate large files away from MBP to save space and onto External Drive? Thanks!
