I have a macbook. Running Mac Os 10.68 Have 211 GB open. 4 GB memory. I have lightroom 4 running on it. I have one Western Drive my passport and have it partitioned 250 memory and 250 for backup. It has quit backing up. I have over 3000 pictures on the storage side that are fine right now. Could someone give me advise on my next move? I was looking at the Seagate FreeAgent GoFlex 1 TB USB 3.0 Ultra-Portable External Hard Drive for $99. Then thinking about reformatting the old drive and see if it will backup and use new one for my pictures. I was trying to empty my hard drive since I am shooting raws and knew it would fill up fast. Money is an issue. I would like to go around $100. It is my understanding that I would have to upgrade operating system to use icloud to Lion. Believe me I know just enough to use buzz words about all this and be dangerous.
