I just did a zero delete on my computer and only have CS5 master suite and Lightroom on my computer now(MacBook Pro 2010). I have 2 external harddrives I'm using. Both are 1TB. I have the Master drive with everything on it, and I want to use the 2nd drive to keep an updated copy of everything. Then I have a 3rd Hard drive, that I want to backup the 2nd backup and keep that off site. What is the best way to go about this?
