Or is Nandroid smart enough to just restore what is needed (for me that would be all my data and settings) and leave all the new bits of the new ROM intact? If so this is the way to go for me as I am sick and tired setting EVERYTHING back up when I want to have the latest version of a ROM.
If you restore a NANDROID backup then it effectively wipes the partition before flashing the saved image. This means if you have an exsiting Rom on your phone with apps and settings and then restore the backup, no part of the previous Rom will remain.
One advantage of a NANDROID backup is that you can select advanded restore and restore 'parts' of the backup. You could flash a new Rom and then restore just the DATA part of the backup thus restoring your installed apps and settings.
The only problem with that is that some Roms at the moment are built slightly differently and are advising that you do a full wipe before flashing so that no settings or parts of previous roms are left that may cause trouble.
So you have a few different options before you. A NANDROID backup would be good for backing up a complete Rom and going back to it in future if you wanted to. A Titanium backup is good for backing up all your apps and app data but you have to reinstall Titanium Backup before restoring your apps and it takes up alot of space on your Internal Storage if you have alot of big apps on your phone. My personal preference is an Adb Backup which you can do through the ToolKit and which backs up all your installed apps and user data (and Internal Storage if you want it to) and saves the backup as a .bak file on your PC with a time stamped file name. This can be restored on ANY Rom and takes up no extra space on your phone.
Hope that gives you the information you need.
