Hello Everyone, this is my first post on here, and I hardly know anything about computers. We are starting a photography company and obviously want to back everything up. We have a 27" iMac, and I just picked up two 1tb g-drives. I would like to leave all of the photos on the external hard drives, so the mac doesn't get slowed down or filled up. So I would like to have anything that gets saved on the first hard drive to get automatically saved on the second. Is there any chance for this? Or do I just have to them saved on the iMac and drag the files over to the external hard drives, and then just clean them off the mac when our current project is complete. We are using adobe photoshop cs5. Any help will be beneficial, thanks.
