cyandelta may fit your needs. It does most of what this updater does, kernel updates and all, by building a small patch of recent changes relevant to your device. There's not a backup feature, but I find it a valuable tool nonetheless. Try it out if you get a spare mo.
On a totally unrelated note, the developer of this app really should change the name and this social media branding. Too many people may confuse this with an official Cyanogenmod app, which will cause obvious headaches. If it is really an amazing product, it can have its own identity and stand out on its own merit. (See goo manager, rom manager, cyandelta, etc)
