is there any need to do any wiping if restoring a nandroid backup? would there be any benefit?
thanks

Nah, not that I know of. I do a factory reset and system wipe just out of habit. I'm fairly certain restoring a nandroid wipes the system partition in the initial steps.

Technically you don't have to wipe because the nand restore process actually does a full wipe for you... but me personally, I always wipe at least cache and dalvik before restoring a nand, just to make sure there's nothing left over from the previous ROM.
When a restoring a Nand backup through CWM, does it actually wipe data,cache,boot etc..
Or do we have to manually wipe everything.
I noticed that when restoring it said erasing boot and stuff.
Asking because i always run into trouble when restoring a backup, Would be helpfull if someone can share the proper way of restoring a backup.

By default restoring a backup through cwm recovery does not wipe everything. If you choose to restore through Rom Managaer you will be given the option to wipe data, cache etc. I would recommended doing wipes manually, just to avoid any issues that may occur from not doing it before a nand restore

Wiping data/cache is enough or should we format boot/system etc?
It'd be better to do a manual wipe before restoring (system, data, cache, dalvik).
Here are some tips on what not to do when restoring a nandroid
A. Forgetting to wipe system before restoring a nandroid
B. Forgetting to wipe data, cache, and dalvik at the same time

Yeah wrong section.
My advice: know which kernel you are on before doing a nandroid backup. Make sure you are on a compatible kernel first, flash the same rom as the nandroid backup just in case.
You know better
Forgetting to run Qkster wipe script.
Sometime renaming the nandroid zip creates trouble.
Actually I was referring to when you wipe everything on ics cwm recovery and trying to restore a nandroid

I've restored nandroids many times and have NEVER wiped anything before doing so without any issues. I'm not sure why you'd worry about wiping everything when it is all overwritten by the restore process.
it happens between the Slim ICS Restore and CM9 flash
I've been thinking. I wonder if it's best to wipe everything (system, cache, dalvik, factory reset) before you do a nandroid restore. I thought I remember reading in a thread once that someone thought some things carry over from the rom you were on even though you restored your previous backup. Does anyone wipe before they restore a backup? I usually don't but this last time I did. I don't think I'm going the notice any difference tho but maybe that's why some people have problems. If they're on a rom that has a bunch of bugs some of them could carry over without doing a wipe before restoring a backup.
If you look at the nandroid procedure it wipes system and data. I never thought of the caches. Hmmm.

What is the process? Factory wipe then restore? Or wipe then format data? Can I format everything then restore? I am coming from BoneStock ROM and restoring to JellyBean v19.
You don't have to do anything. I always do a factory reset then restore my nandroid. The restore will wipe System as its first step anyway so doing anything more is optional not required.
