back up manila and/or reg

[enzyme]

I am looking for an app(s), preferably free, that can back up and restore registry and manila files at the push of a button. Some that works like PIM Backup.

I am on Sense2.5 There are lots of themes and fixes / edits to manila that I want to try. Being that there are so many bugs and incompatibility issues with in 2.5 (especially on TP2). Sometimes simply uninstalling the cabs will not take it back to the way it was, and it stays that way unless I hard reset.

I am too lazy to re-install every one of my apps each time I want to experiment. That is the reason I don't try most of the things I would like to. Is there a solution to this? Something like this for reg edits would be great too but more importantly is being able to back up manila.
