I backed up an image of my drive a few months ago, right after I got Acronis 9. I split into three DVD sized files totalling 11.7 Gigs. After I repartitioned, installed Vista beta, then decided to go back I restored from that image. Worked great! Now I go to update that, so I did an incemental backup hoping that means: 1. The additional image store would be very small, just the new data. 2. I could later choose between restoring the original image, or restoring the original plus the new incremental data. What I got was an additional 3 DVD sized files totalling 12.5 Gigs. Now I have 24 Gigs of files that would just be 12.5 Gigs if I did a full backup again. And, when I start a restore, it looks like I can only restore the entire 6 files...meaning I can't just go back to the original backup image. So, why did I do an imcremental backup? Seems like I should just take a full backup image. It will take the same amount of space, and I'll have more options. What am I missing?
