Our software is SO primitive still (Windows, Linux, Mac, all of them) - When is someone going to just completely alter the entire paradigm of digital data beyond MBRs, aligned partitions, clones, backups, operating systems... there is definitely a better way to store bits in a secure, redundant and SIMPLE fashion - even VonNeumann architecture could probably give way to biologically based neural networks. End Rant.
@ElectricRhino - it takes me months in between when I have time to address these issues, but I have found some interesting software, perhaps you know of it already:

This software is basically ONLY used to CLONE drives, and whilst it doesn't do the incremental cloning you speak of, it does allow the SCHEDULING (unlike Acronis, or nearly any other software I've found out there) of the Clone operation, which allows for automated maintenance of a (relatively) up to date clone drive.
While it won't be the incremental version you've mentioned - presumably if you do it frequently enough you can mimic that functionality to some extent.
There's a free trial I'm going to test.

On a more general note - currently my strategy is to use Acronis to create Images with incremental backups of all my data AND primary OS drive. I used the PlusPack add-on to Acronis TI2013 to create a Win-PE bootable media Disc which provides the boot environment to restore the images.
I then maintain a separate clone drive which I've been doing manaually with Acronis.

Basically, Cloning of HDDs is apparently deprecated as a backup solution for its inflexibility. And while this has merit, I think what is not well conceived is that it's NOT a replacement for backup, in fact.
What "Cloners" are REALLY trying to achieve is what RAID in theory does (but has all manner of complex issues that a non-server running person probably doesn't want to deal with (drivers, firmware, etc.).
A clone drive is essentially just a slave-drive as they called them back in the early 90s - a REDUNDANT harddisk that, while not as seamless viz. uptime as RAID (as the system DOES go down for a time), still restores the exact system to its pre-fail state more-or-less instantly, without the need for BOOT environments, and without the need to worry about RAID issues.
In my opinion - it's a redundancy strategy, not a BACKUP one, but that doesn't means it's less useful. I think if people understood it better, and it was marketed better (particularly with the cheap prices of large HDDs out there), I think it would catch on tremendously. It makes SO much sense afterall.
Analogously - it's like a backup electrical generator - in fact, the most sophisticated format of this doesn't even exist yet to my knowledge - which would be completely independent clone drives that fail over seamlessly (again, RAID-like, but without the problems).
