My good friend is a professional photographer who, while not totally inept on Macs and photoshop, is not necessarily a computer whiz and needs help setting up some sort of easy backup system. She has a Dual 1.8 G5 with 2gb of ram and wants to set it up to run all of her photoshop projects. The computer only has an 80gb HD in it, and she is going to replace that with a two 250gb drives along with a 1TB My Book Pro II from WD. She is going to be working on about 2-5 projects at a time that will be no greater than 15gb in size each. Her main concern is backing everything up all the time and not risking or worrying about losing all sorts of files in a crash. My initial thoughts are to partition the internal drives- one 120gb partition for apps, and then break the rest of the space up into multiple sizes that would handle a variety of projects. Here's where I (we) start getting a little bit confused: the WD My Book 1TB supposedly has two internal 500gb HD's. I think she wants the first WD HD to mirror the two HD from inside the G5 (I'd assume in RAID 1 config) and the second WD HD to mirror the other HD inside the My Book. She also wants either one-touch backup or it just to backup up periodically so she has to do nothing. Here are my main questions: 1)Is RAID 1 the proper config, since redundancy is the main goal? 2)Is it necessary to have one of the internal 500gb HD's inside the WD My Book mirror the other? 3)What's the best and/or easiest way to create this whole configuration for a moderately computer literate person? 4)What's the best way to change the boot drive from the 80gb to one of the 250gb? She has all of her programs (photoshop, final cut, shake, etc) on the 80gb but wants to get them on one of the 250gb. I told her to sort through and look for all the licenses just in case she has to uninstall and reinstall. Is there a way to setup a new boot drive and put the programs on it without all the hassle? Thanks for the help!
