[Q] Nandroid 2.3: which files to maintain?

---

I have installed Nandroid 2.3 thru clockworkmod recovery 2 month ago.
1. How should i take a backup of this OS?
2. And the zip folder through which i had installed 2.3 should i delete that from my SD Card? Also there are many other files like zImage, Readme.txt, log.txt, initrd.gz...cam i delete these too?
3. Previous to running Nandroid 2.3 i was running 2.2 through SD Card. Can i delete that folder too?

1. You can back up via CWM > back up and restore > back up
2.The zip file is needed for the installation. You can delete it, but the other files - NO.
3.The folder of previos rom - if you don't need it ... delete it to. She was for other rom. Now your rom is running from NAND.
