Hi - First time poster here. I just backed up (and am in the middle of testing the Archive Integrity) about 74 gig of data from 3 drive partitions on my XP SP2 to a separate hard drive. So far, so good! If you can't tell already, I am VERY much non-technical, I feel kind of fortunate things didn't blow up as I got to this point! I wonder ... do I need to trust the Archive, or is there a way I can confirm that I will be able to truly replace the contents of my computer's hard drive? I don't understand how the 74 GB of data gets stored to a 10.2 GB archive size, if that is compression, that's not exactly a mirror image I'm guessing, but I guess it doesn't matter? I'm doing all that on a non-internet computer, I had to go back and forth with USB drives and pieces of paper to make it work, but the computer needs to be not connected to the internet (it's a music production computer, and bad things happen more when they're connected to the web). I wrote all that so you'd have an idea that I'm not a techy, just a regular end user kind of guy. Given all that - is the free one good for me, or do you think there are big advantages to my shelling out some $$ for a paid version? Thanks so much for reading all this!
