[Q] TWRP Backup and Restore question - Android Q&A, Help & Troubleshooting

Hi guys... I have a quick question..
I want to make a nandroid backup before I try a custom rom, so i can simply restore my backup if i dont like the rom.
I only have about 1.8GB left on my internal storage... I dont have an external sd card right now.
The backup size is about 2.8GB... so I am 1GB short...
My question is, if I backup System and Boot as first batch, then transfer the file to my PC to free up my phone again, then backup Data as 2nd batch and transfer that to my PC again..... now once I want to restore my backup, will those 2 batches of restore process work or not? Im not sure if a nandroid backup needs to be a single file only.... Im out of storage capacity that's why splitting the backup is my only option
thanks in advance!

Backup Question

Hi
Just wondering about the different backups that are recommended before reflashing
You can do an apps + contacts type back up with say titanium. I take it you then save these back ups to say a desktop/laptop.
My question is, what does the NAND backup save, where is the backup saved and the next step is usually to do a full wipe. Does this not wipe what you have just backed up?
Thanks

Hello Macolli,
you are correct about the titanium backup, but personally I just let the backup remain on the SD card. The nandroid backup consists of filesystem images of the phones internal memories, and are also stored on the SD card. They are located in the "nandroid" folder, one subfolder per backup. The full wipe only clears the internal memory areas in the phone, not the SD card.
Br,
Henrik
thanks, that clears that up!
Sorry for the further questions,
If I have 2 or 3 ROMS i want to try, and test each one for a week or so once i find one i prefer can i just to a restore of that ROM from the NAND option or is it best to reflash?
i would restore it because then i would not have to download the apps again

How much space does nandroid backup use?

My s3 is a 16GB one and I have 3GB free. If I do a nandroid backup will I need over a 13gb sd card?
generally they are 2GB or there abouts. It varies depending on what you have installed and the rom etc.

So what does nandroid actually backup?
If I've used 13gb, how is the backup only 2gb or so?

it doesn't back up your internal or external sd cards, but it does backup all your system data and apps, user apps and data
Ok so if I do a nandroid backup and I flash a new ROM and something is ot working thwn reflash from the nandroid backup, will everything like apps and their data, photos, settings be the way it was before I flashed a new ROM?

Yes... flashing shouldnt touch your media files like photos or music (internal/external sdcard)

I'm not so sure about that. When you restore, I thought you definitely want to be on the same Kernel as you were on when you created the Nandroid and to be safet it's also good to be on the same Rom as you were when you created the Nandroid backup. Otherwise... bootloop and ugly stuff. At least that's what I get from poking around the Infuse forums (my phone)... mileage may vary with S3.
I'd be interested to hear if others have opinion on this. I stumbled onto this thread while searching about Nandroid procedures.

[Q] EFS Backup

Hi all,
need to ask a couple of questions regarding the EFS backup.
1) If i use the kTool for EFS backup and do a total wipe before flashing custom ROM, (mounts and storage>format system) will the EFS backup also get wiped out? My common sense tells me yes since the internal SD will be wiped out and kTool saves the EFS files on the internal SD but just want to be sure so that i can search an alternative method for backing up as i want to flash custom ROM with total wipe.
2) Does the EFS Pro app save the EFS backup on the internal SD only or does it have an option to save on ext SD card?
3) Do i just have to be rooted to backup my EFS files? Im just asking as im terribly obsessed my EFS files will get corrupt while rooting the phone! Is there a simple way to backup my EFS files on my ext SD card without root?
4) Can my EFS files really get corrupt just by rooting my phone?
Thanks in advance for any feedback

I know nothing about EFS backup but how about this. I assume you have access to a PC and the usb cable that came with the fone. Or else you do have a microsd card in the fone. Why don't you do the backup and copy the files to either the microsd card or a PC. That way you know you have a backup you can use.
In most cases, and someone can correct me if I'm wrong, the format system will not touch your backups.

Yes very true, i can also do that and it also crossed my mind but im afraid that by doing so, copying the EFS files and folders onto a PC or directly to the ext SD card will alter the files and folders in a way that they cannot be restored and i dont want to take that risk unless im totally sure of what im doing or if this can actually be done.
Thanks just the same for ur feedback
Ok so I just found out that with EFS Pro I can backup on my pc safely. Do I need to be rooted to use this app and safely backup the efs files?
Thanks

[Q] Does Nandroid backup the internal storage??

Hi guys,
I own a S3 and for one year I just dealed with the stock ROM, just root access. Saturday I decided to enter the modding world but I knew it would bring a lot of troubles...
I did a nandroid backup of 4.1.2 stock FW just before the flashing, but no way it restores, after an hour of processing it shows - Error restoring data! - it boots but it's a total mess. I even restored the original stock FW with triangle away, wipe all and double ODIN flash and then reflashing the clockworkmod recovery to restore the backup again but nope, won't work.
Luckily I did a full backup with Titanium backup prior, the real trouble is with ES file explorer: I did copy/paste of the entire internal storage to the external microsd but for some reasons it stopped at "D", "Downloads" folder... I lost everything else and I realized this only AFTER wiping and flashing, of course...
I'm trying to recover the files with Hexamob, hope this will work....
I have this two questions:
Does Nandroid work only with backup < 2.5 Gb? Mine is 4.5 Gb...
Does Nandroid backup the internal storage, too??
Thank you all guys

If I am not wrong, Nandroid does a backup of your phone (system, data etc) so that when you restore it, you got anything like it was. It does not backup the SD card though. In addition backups of over 2.5gb should work.
/data is the internal memory? Or is it /sdcard?

its all the internal memory.
/system
/data
/cache
...are all on the emmc memory and are backed up in a nandroid backup.
/sdcard is actually a mount of /data/media, however this is ignored by nandroid backups for obvious reasons

So /sdcard is the external microsd? And /data is the internal memory (I mean what you see when connecting phone to PC, Internal memory and external sd)?
If nandroid backed up internal memory would be great, may be there's some way to recover datas from backup files (unyaffs won't work, Titanium Backup just shows apps and their datas).
I'll do some further research.
no. sdcard is the internal SD, which is just a link to /data/media. to backup it, use copy and paste. no, it's not possible to recover internal SD data from a nandroid backup
Be aware that Nandroid does not backup your EFS .
jje
it can. depends on the recovery
Yep i know problem is that some think any recovery backs up EFS .
Wrong recovery no EFS backup .
We desperately need some stickied faqs and guides on this forum .

/sdcard is the "internal sd"
/extSdCard is the "external sd"
/data is something different that just so happens to be the home of /sdcard
As I feared, no internal storage backup in Nandroid. But what makes me more angry is that s****y ES file explorer so crappy it can't even perform a simple task like copy-paste. If that worked I wouldn't have lost anything. :crying:
Not to mention the useless nandroid... doesn't work either.
However I did manually backed up the EFS folder, but I don't really think it matters in this case.
If your /sdcard was 90% full, where would the nandroid go? External obviously? But recovery devs cannot assume that everyone has an external sd card with enough free space to store a 15 GB backup.

Just clarifying
Hey guys, this is my first ever post on xda!
Just to clarify, a nandroid backup will only backup device root files, and not the (internal) sdcard, nor the extsdcard files, from my understanding of this thread. So to do a complete backup of ALL phone data, I should perform the nandroid backup to extsdcard, and then simply copy (internal)sdcard and extsdcard to my computer for safe keeping?
Thank you!

[HELP] Does a CWM / nandroid backup includes WhatsApp images?

Yesterday I whiped my internal storage. Sadly I forgot to secure my WhatsApp images from the respective folder.
Before whipping the device I've made a nandroid backup with CWM.
The question is: does a nandroid backup includes also the images and videos from the internal storage folder of WhatsApp? Can I restore it with the nandroid manager?
I would be pleased for a fast answer :good:

Yes it should because it backed up /data which some devices have their internal sd partition. Extract the data and see. It should be there as long as you didn't store images on the external sd.

So you're saying that there was no backup in the first place? Or it was wiped?
There is a backup on the external SD. What I meant is that I used nandroid manager for a restore but it only restored the WhatsApp data and sadly no images or videos at all. Maybe there is another possibility?

A cwm backup will restore data but it won't restore the files.
