I've done a complete back up of my c drive with Acronis true image!My c drive is 76.3gb(it's an 80 gb drive)with 38.3gb used space yet the complete Acronis back up is only 35.5gb?Is this because of the compression method used?P.s the compression was set to normal!Thanks!
Partly the compression, but also partly because Acronis does not (to my knowledge) include your page file or hibernate file in the image (as they don't contain any meaningful data for the purposes of an image). Acronis just records the page and hibernate file details (e.g. size and location) in the image and then recreates them on a restore.
BTW, for contrast, my C partition (basically WinXP Pro & Programs) is 12GB, 5.6GB used and image is approx 3GB. My page file is 0.75GB and no hibernate file. Image takes around 3 mins to create / restore.
