If its your still with the official ROM, I assume you didn't even create an ext partition yet.
Therefore, at this point you need the "Nand backup" option.
Assuming, you want to install a custom ROM with app2sd support (most custom ROMs), you will need to:
- backup the entire contents of your SD card to the computer (all data on card is lost in the next step!)
- repartition it through recovery, say to: 0 swap (unused), 512M ext2 (not ext3/4), and the rest for fat32.
- restore all files you backed up.
After you have made an ext partition and install a custom ROM, use "Nand + ext backup" to back it up.
Finally, restoring is always using the "Nand restore" option, regardless of which type of backup you made.
thanks a lot...

I have an SD card with 3 partitions: fat32(7gB)/ext4(488mB)/swap(91mB). not sure what order I created them in, and not sure if that matters.
when I do a nandroid backup, is it also backing up my ext4 partition where my apps2sd apps are kept? I want to be able to use nandroid to swap between many different ROMS, but still have all my settings saved per ROM. And hopefully apps as well, whether it be by the nandroid restore or (and im not even sure if it works this next way im describing) by different ROMS being able to see the apps in apps2sd and use them?
Like I said, Im not sure how apps storage/location actually works. If I install apps on the sd card, and I put an upgraded or even a different custom ROM on, does the system see the apps on the new ROM? Or are we also supposed to wipe ext partitions as well?
Can someone let me know what "wiping" data and/or cache actually does? IS there a basic phone architecture doc I can read to see what data / cache actually is used for?
Wiping refers to the internal memory of the device. Not the SD.
By wiping you remove all settings and software installed on the device itself.
If you boot after a wipe, you will have to re-enter your google account information and wait for the sync to complete.
If you have apps2sd, (most of) your apps will be on the ext partition on your SD card. Those don't get deleted when you wipe. If you have go from 1 apps2sd capable rom to another, your apps will still be there. And the apps that store settings on the SD will have their settings saved too (only one I know of is gem-miner).

I recommend using a more complete back-up and restore tool like BART or Switchrom. Do a search for BART on the Dream Development forum and you'll find everything you need. It's built in to the latest RA recovery images as well and works great.
I don't have any partitions and I'm not even sure that would be a reason to not let me backup. I can run Nandroid backup fine but I can't run Nandroid backup +ext.....Can Someone please help!
Thanks

tweet me @robotnoize1 if possible...thanks!
I've had this problem before when I rename the nandroid file.
I usually power off, go back into recovery, and it works.
Not restore but backup.

You have no partitions so backup + ext does not apply to you. That is the default error when the script doesn't detect an extX partition to backup.
okay.
Exactly, an ext partition is for the apps to sd technique which you are not using, so there is no need for an ext backup, a normal nandroid is just fine
And my apps messages etc. will all be backed up?
well it's time to try it now I guesss!
Thanks for the help guys very much appreciated!
I do believe you messages will be, however your apps will not! but a simple visit to the android market and then to your download tab will bring up your list again Otherwise just create an ext partition and do a nandroid+ext backup and that will save your apps.
Correct me please if im wrong, but hasnt the RA recovery been having issues with ext backups on cyangen?

You are wrong.
Nandroid does backup the whole phone, everything under "/". By everything I do mean everything on the phone storage.
also, make sure it is fully charged before trying to restore.
Every time that I flash a new NAND build (almost every day), I find myself at list one hour seating and installing all the apk files on my sd card.
Is there a way to install all the files on the first boot ? to save them on one folder and on the first boot android will install all of them ?
I know that in SD card builds it's possible.
Please advice.
No, that's not possible. It was a feature of SD builds only.
Why not use Titanium Backup to backup all your apps and data, and the restore them all with just 1 click (if paid - lots of clicks if not!)
Or keep your apps on a rom with ext partition support.
Backup in nandroid, wipe, install new rom, reboot cwm, restore backup where you can choose, select SD ext part.
Reboot, enjoy not having to install all your apk files

Hello,
nandroid is a backup tool. It is run from recovery mode, and makes a copy of the internal memory of the phone and saves it on the SD-card. It can also backup the apps installed on the SD-card in the same manner. It is often used when flashing new roms to the phone, since it provides a means to fully restore the phone to the previous state.

So if i did a nandroid back up on my phone it would back up everything onto my sd card and then restore it to its original state (ie nothing).

Yes, the nandroid image on the SD card is an exact copy of the relevant parts of the phones internal storage, so when doing a restore everything will be back as it were before. If, however, you have apps installed on the SD card using Froyos apps2sd (which stores the applications on the ordinary fat32 partition of the SD card) those applications is not backed up. Nandroid includes functionality for backing up apps installed on a ext partition, though.
Personally I use Titanium backup to backup applications when I'm changing ROMs.
Br,
Henrik
Does Nandroid overwite previously made backups, or will it make a new backup every time? In case of the latter, can you choose from recovery wich backup you want to restore?
(Before I flashed my Hero, I made a Nandroidbackup of the original ROM. I don't want risk loosing this backup when I make another Nandroidbackup.)
I think it overwrites, but i'm not sure.
No, it doesn't overwrite the old backups. You can choose which image to restore.
Br,
Henrik
Tanks for your reply!
Hi all
a question about cwm i have looked around and have seen the instructions for the various installs of the different mods, but the one thing i am unsure of is the ext partition on the sdcard if i create a cwm backup of the current mod i am using does it backup this partition and then if i install a new mod must i make a new one?
sorry if i am not making sense i am just trying to understand the total backup procedure for a mod and restore function of cwm and testing different mods...
thanks all
Hi,
The backup makes a copy of the contents of the partition. If you flash a different ROM requiring a different partition layout or CWM configuration and want then to go back to your original ROM, you will have to create the original partition and CWM configuration you used. The backup you created, once restored will then function as it did originally.
