Titanium backup also backups all your system data so that whenever you do a factory reset ot flash a new ROM, you can easily restore your favorite apps, settings and whole appearance of phone.

If you are using a SD Card, remove it before rooting and insert it again after rooting has been done. Backup all data on internal storage on your computer.
