I disabled backing up, how to I re-enable?

[Chodite]

I disabled backing up via this excellent trick but since I haven't had a clean backup in a while, I'd like to do one (even if it does take an hour). Any idea how I re-enable this process?

Its right there on the page you linked to.

Changing the 'true' in step 3 to 'false' will re-enable the backup feature.
