A really great plus of the paid version is Rapid Delta Restore. If, for example, you screwed up permissions on some files in a system folder which is hard to undo, and can stop parts of OS working, or you deleted some files but did not know what, then if you restore the backed up image from earlier over current install, it only restores the differences.
I did this recently and the Restore took 2 minutes instead of usual 30+ minutes.
Of course, any new data since last image backup is also removed if on partitions being restored but that is no different to any restore (also why I keep data in a separate partition).
