I see nandroid images how do I reinstall in case of a failure

Nandroid images are restored from within your recovery...
You would boot to the recovery, data wipe, cache wipe, and dalvik cache wipe, then restore the nandroid backup from the restore sub-menu of the recovery...
Note: you must ensure that you have the same recovery that created the nandroid image...I.E. CWM for those images, or TWRP for their respective image.
They are "NOT" compatible..
It's toooo easy....g

If I need to restore a nandroid do I need to wipe/factory reset everything prior as instructed when installing new roms?
Or if I need to restore a nandroid can I just boot into cwm, go to restore nandroid, restore and go?
Is there a difference?
Just restore the nandroid. Recovery first formats all partitions and then copies the backup images. It's all automatic, so it's redundant if you format manually first and then restore.

Does system recovery "Wipe data/factory reset" resets custom kernel to stock?
I'm asking this because im noob, and I want to try JellyBlast for Galaxy GT-S5570I. It has two zip files to flash one is ROM, and one is custom kernel. If I do something wrong I'm afraid that I won't be able to restore nandroid backup.
Sorry for my bad english.
No, that just wipes app data and other user data, resetting the phone back to factory condition. Kernel is in the /boot partition, with it's related modules in /system partition along with the rest of the ROM files. So flashing a stock ROM will restore boot partition and system partition to stock too, including the kernel. No worries in your case. Just take a nandroid backup and flash the ROM and kernel. When you restore the nandroid backup, it'll automatically wipe the /boot and /system partitions and restore the ones in the backup, so you'll be back to your old ROM with old kernel.
im gonnna show you how to downgrade htc Droid dna MUST BE S-OFF AND UNLOCKED WITH TWRP OR CWM!!

If they format data, they're going to need to adb push the file in the step before flashing. You should also specifiy that's only flashing the rom and has nothing to do with firmware or radios. Also you mentioned to make a nandroid backup in step 1. But your step 3 would erase that nandroid backup so I'm thinking you need to add the step of moving the nandroid backup files to a different storage device or don't have them format the data partition.
If I was new enough to need these directions and made a nandroid backup in step 1 and followed the directions and realized that I had formatted data which erased the zip I was supposed to flash as well as my nandroid, I'd be quite pissed, but worse I would be frustrated and defeated, and I would hate to see that drive away some users.

I thought that "format data" didn't touch the virtual "sd card". It just wipes the apps and app data. But there is another option to wipe the storage. When I installed a ROM I chose in TWRP to format data, cache, and davlik from their wipe menu. It did not touch the Downloads folder I had saved the ROM to.
Factory reset in recovery is what you are thinking of, which is equal to "format data excluding /media"
In the factory reset menu it says something like "wipe data -/media, cache, and dalvic cache"
If you go to advanced wipe, and wipe the data partition instead of using the factory reset selection it wipes the entire partition, doesnt exclude /media which is the location for /sdcard

If I restore back up I made with CWM with it will it flash Rom too?
I mean let's say I have stock Samsung Rom then I flash the cm back will it be like flashing new cm Rom but with my apps and settings already?
Restoring android backup take your phone exactly at the moment the backup was done. Rom, kernel, apps, data, everything.

A Nandroid backup takes images of your partitions.
If you want to restore a previously made Nandroid backup, enter Recovery Mode select Restore. Everything should go back to how it was when you made the backup.
If you choose the ‘Advanced Restore’ option, you can select which component of the backup to restore – like the boot, system, data or cache.
Downloaded apps, apps and OS settings, contacts, messages are backed up in data (/data)
boot has the initrd.gz and zImage.
system has the system files (/system)
cache has the cache (/cache).
SD-ext has the ext partition
TWRP for the OPX brings up the partitions below:
System
Data
Cache
Persist
Boot
Recovery
EFS
I wondered which ones I should be backing up for standard nandroid backups? I used to do System, Data +/- Cache on my OnePlus One. I did EFS once and backed it up externally and on the SD card, but never restored it.
Do we need to backup all partitions every time?
More importantly, do we need to restore all partitions if restoring an older nandroid of the same ROM or one from a different ROM?
Many thanks

All recommended.
You can store your backups on SD card and forget to worry about the sizes.
