Depends on your configuration. You're not saying anything about your phone, ROM version, nothing... how should we be able to help?
Anyway, here's a small guide:
- Nandroid backup simply backs up the OS (data, cache, boot, system);
- Nandroid + .android_secure = OS + applications you installed or moved to sdcard using the OS (not a2sd);
- Nandroid + .android_secure + ext = OS + native apps on sd + a2sd apps = everything.

Depending on the rom you run, and the partitioning of your sd, not all of the options that Masteryx described will work, you should do some reading on recovery. But for sure you could use the first option, nand backup, it will bkp your system. You can backup you apps with Titanium, so you have everything covered.

OK, if you're using Megatron you can choose any option (all of them will work) but recommended is Nandroid + android_secure + ext (option 3) because like this you will have a complete backup.
Because of the bad translation I can't understand what you need next. Try again, using different words.

Oh thank you very much.
My problem 2: In the process up ROM, the first choose Partition SDcard. Is this option required in the process up ROM?
Because when I choose this option, my SDcard lost almost 1GB and must format it. Do you understand? Again Im sorry

---

Oh...I choose option3 & error
Error : Run 'nandroid-mobile.sh' via adb

---

Yes, I understand now. Mostly because you have that error I understood what happens to you.
In the process of installing a custom ROM, you encounter the instruction to "Partition the SD card" from the custom recovery menu, and you want to know if this is really necessary. If the ROM developer said to partition the SD card, then you definitely should do it. If you flashed Megatron, you had to partition the SD card, create an 512 MB ext2 partition which then had to be upgraded to ext3 and finally to ext4. Also, if you use Megatron and followed the installing instructions you probably still have ThunderG custom recovery v1.1.0. This version can't back-up ext4 partitions, that's why you get an error when you choose "option 3" from nand backup.
Update your ThunderG custom recovery to v1.2 using the "flash_image" from here and the recovery image from here. Extract the files from the archives and put them on your SD card, then type these commands in console (do not type the $ and the #):
$ su
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system
# cat /sdcard/flash_image > /system/bin/flash_image
# chmod 755 /system/bin/flash_image
# mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak
# mount -o remount,ro -t yaffs2 /dev/block/mtdblock1 /system
# flash_image recovery /sdcard/LGp500-recovery-v12.img
# reboot recovery
Click to expand...
Click to collapse
If you receive a "File not found" message at the mv command, don't worry and continue with the rest.
With the updated custom recovery you will no longer receive an error message when you will do nand + android_secure + ext backup.
As for the missing space from the card after partitioning, it is normal When you create an ext partition, it takes space from the SD card. The rest of the space is used for the FAT partition. The ext partition is not visible from the phone or from Windows, that's why it appears that your SD card capacity is smaller.

I tried but not working
on the LCD phone whether Build : RA-thundderg-1.2.0-gnm but error. Not backup. I think del old nandroidbackup on sdcard
Thanks

Please make sure you have enough free space on the card for the backup. If it's still not working, try any of the other options, you will have a backup which can restore your phone if it doesn't boot anymore, but you may lose some applications. No problem, you can reinstall them.

For option 2. it working good maybe not enough memory card. Almost 5GB I don't know have enough to backup. Anyway, thank you very much
