I've been using Paragon Software's Drive Backup utility for years. I do full system image backups from the booted OS, not outside it, so it's very convenient,
I have two RAID volumes, one system and one data on different controllers. My routine is to do an image backup to the data RAID volume, which takes me about 2.5 minutes for 28GB, and data image to the system volume, which takes about 1 hour for 500GB. I then copy the images to an external simple drive for outside storage using a BAT file that asks the target drive and the image files to copy, and also copies current versions of special files like my Outlook mailbox.
This allows me to do quick restores for non-catastrophic situations, like regressing to a previous OS state after something screwed up my OS config. System image restores are done using a WIN PE recovery DVD to which I have added my RAID drivers
and I can restore that image to any hardware that has the capacity.
It also has an archive explorer that allows me to restore specific folders / files from a backup image.
