I really don't understand the time worry. When the imaging starts, there is a 'hide' button. You click that and go on doing something else. Macrium then minimizes to the tasktray where you can always check progress or unhide it. But when it is done, it reappears automatically.
And regarding the wear and tear, I really do not think that this is a problem. The normal OS operation reads and writes a thousand times more each day.
Btw: I assume you know that you can schedule the Macrium images - e.g. at a certain time of day, or at boot time, etc. Just right click on the xml file and you will see.
An alternate backup strategy is to create weekly images plus daily restore points for the case that something happens during the week.
