I've just been trialling Macrium It seems pretty good. It has a Good UI and is very easy to use. I backed up an image of my Windows system/boot partition of 40gb and it created a compressed image a fraction of the size in a few minutes. I removes empty disk space and compressed pretty quick it would seem. For system restore, the free version provides either a UNIX boot disk or a Bart PE plugin. Both seem to work OK for me but I prefer the Bart plugin. I made up a Bart disk with both the plugin supplied and a copy of my system partition image which has just been installed and populated with my usual core apps. So that one CD should be capable of an emergency restore. I partially tested this and my other PC booted to Bart, the plugin worked and it was all set to go. i didn't actually restore the partition. The paid version supplies an integrated Windows PE boot disk which is a neater, simpler option. but the Bart building process was not hard anyway. The free version does not do incremental backups. not sure about the paid version. But then i don't THINK I really want them. Maybe I'm missing something here but it would seem better just to back up actually user data using Cobian or something which is a pretty fully fledged free backup app with incremental and differential backups etc. My main motivator is just having had to rebuild my PC which took most of a day. A system disk image could have saved all that time and effort. What is the advantage in using images for large amounts of data backup rather then file backups?
