I have XP Pro, Pent 4, 3.2 ghz, 1 gig RAM. I am a newbie who is trying to create a backup strategy for my computer. I am going to purchase Acronis True Image based on everything I have read about it. I bought the Maxtor external drive with Christmas money. It comes with backup software called Retrospect Express HD. I have a couple of newbie questions: 1. Can I install the Retrospect Express software and use it as well as Acronis? Or should I just use Acronis? (I like the idea of using the "one touch" button to back up "my pictures" after photo-editing and down-loading.) 2. Do I install Acronis on my Maxtor external drive (which I will use solely for backup)? Or do I put it on my C: drive? 3. I frequently defrag my hard drives. I read in a computer magazine that one could experience backup problems with defragging and using image backup software. Is this true? I read the FAQ and surfed to find these answers. My apologies if I missed them. Your help and advice is much appreciated. Thank you in advance.
