When I try to backup with TWRP I get the message ''TWRP createTarFork() error 255 when backing up data''. After googling this error I found out that I needed to ADB pull the log. I did that and I think that I know what the problem is. But I am not sure how to fix it now. Here's the log: I can't past the log because this is a new account. Send a dirrect message for the log.
Edit 1: I think that this the error is: I:Check_Lifetime_Writes file does not exist '/sys/fs/ext4/system_a/lifetime_write_kbytes'

When I had twrp installed and tried to backup I would always get the error 255.
When I boot a twrp img from fastboot, a backup will succeed. (fastboot boot twrp*.img)

I could resolve my nandroid /data backup error on my EMUI 8.0 Mediapad M5 device with those following steps:
1 - Use a correct TWRP implementation
TWRP need to access the uncyphered partition /data.
There no possibility to backup it, if TWRP does not implement deciphering user data partition.
2 - Remove all users except user 0 (the administrator)
You can verify that there is no unwanted users, looking at directory /data/user : the only subdirectory should be "0".
To remove the others users :
Remove the PrivateSpace if you have one (Settings > Security & Privacy > PrivateSpace, and tap on the garbage can).
Remove all the secondary users (Settings > Users & accounts > users, and tap on each users to delete them). Keep just the main administrator user.
On EMUI, remove all twins applications (Settings > Apps & Notifications > App Twin, and disable all twin apps).
On OxygenOS, remove all parallel apps (Settings > Apps > Parallel Apps, and disable all parallel apps).
On MIUI, remove all dual apps (Settings > Dual Apps, and disable all dual apps)
On others devices ... you must find all parameters that create those unwanted users.
If you are not able to get the correct settings to suppress those users, in last resort you can try this command : "pm remove-user user-no. (For example "pm remove-user 999").
3 - Do not forget to protect your backups by a password
This would be stupid to cipher your /data partition and keep backups of this partition unprotected.
These steps fixed the nandroid backup problem for /data partition on my Huawei Mediapad M5 device.
I post on this forum because I hope that this will be helpful for others devices owners.
Well I use fastboot and "install" twrp in my phone (Xiaomi Redmi Note 4x MediaTeK). I have already put to my sd card SuperSU zip ( version: SR5-SuperSU-v2.82-SR5-20171001224502) and I click install, I choose SuperSU.zip file and swipe to install. It shows this message:
Code:
-Mounting /system, /vendor, /data and rootfs
-Extracting files
-System mode
-Disabling OTA survival
-Removing old files
-Creating space
-Placing Files
-Post-installation script
-Unmounting /system and /vendor
-Done !
Updating partition details...
...done
After this I believe that SuperSU is installed but when I click reboot system, it shows me the message "No OS installed! Are you sure you wish to reboot?"....well I rebbot and let it for 20 mnutes.....nothing happend......I tried it many times, still nothing, I tried many versions of SuperSU....nothing, I tried to flash with the same way lazyflasher-no-verity-opt-encrypt.zip......nothing, I dont know what to do
This is a Flashable Zip for restoring backups created from different recoveries. No more problems with checksums, checksums will be ignored.

I need testers for proof of concept. If you have a Mediatek Phone with encrypted userdata_20160823_100259.backup, please try to restore with bckp2raw.zip from TWRP. Please give feedback if failed or vote :good: if worked.

Is this solves problem of Android 7 stock recovery backup?
I got second phone stock recovery problem for 7 version
stock recovery do not want to recover his backup. complains - "it is corrupted, please reset your phone"
I install twrp recovery and try to install this .zip
bit it give error 134 (or something like that)
sorry this project is abandoned. in generally, backup can not restored to other device because of the checksum mismatch. Thats where this zip comes in game. If you upload recovery.log right after installing this zip i will try to fix the errors..

data partition is encrypted
Hi , I've been trying a lot of methods to get my data back from my .backup files. All with no results. Your bckp2raw script seems to be one of the most successfull , but it ends by a " data partition is encrypted" ... Do you think I can still recover my files ... The original phone is actually working but it has been factory wiped ...
that message just means that your current /data partition is encrypted (message for encrypted backup is different)
- do a backup of metadata partition (just in case)
- do a backup of /sdcard to PC (adb/mtp)
- format userdata partition
- reboot TWRP
- check userdata partition is unencrypted
- restore userdata*.backup from zip
- restore metadata partition from backup
- restore /sdcard backup
the restoring process will deny if userdata is not empty. please note if backup is encrypted it is most likely useless without corresponding backup of metadata partition

Thank you very much for your quick reply. Ok so I tried it , the restoring part worked , but when I rebooted it asked me for my code and said "password is correct but data is corrupted" ....
Do you have any idea for me to get my data back .... at least my pictures ...?
sounds like the backup is encrypted, can you confirm? more important is this the source phone of this backup? or do you try to restore on other device?

I'm pretty sure it is encrypted. Yes the phone is the source phone of the backups
encryption should work in theory, but you need a copy of metadata partition from the day you created backup. you most likely don't have it, therefore your data is lost forever

Yes I don't have the metadatas from that day, is there a chance that they have been backup with the android backup ?
Thanks for your help anyways, I'm sad
no, nothing you can do. even a old metadata from the first day when you buyed this device would probably do it. metadata partition is formatted on factory reset.
for some devices the crypto footer is not located at separate partition, but at the end of userdata partition instead. But this is not the case for your device, otherwise this zip would have restored. you can double check, search with hex editor in last -16384 bytes of last file for string aes-cbc-essiv:sha256 (or aes-xts)

Cannot find anything like this but i'm not used to HEX reading .... Is there a chance that the metadata is on the SD card i was using for (external) storage on the phone (not the ones for the backups) ?
Hello there and thanks for creating such a productive thread, just what I needed for my current situation. so am trying to retrieve .backup files on cxAir android 7.0 after root through twrp but apparently, when running the script from the zip file you've shared I get the Error: data partition not mounted.
I'm still new in the dev world but am totally excited about it and I may not understand a lot of things but am willing to work my ass off to figure out the most of what I can so please I'd really appreciate it if I could get some help on this one, thanks in advance
mount data partition and try again?
Someone help me please!
custom rom = (Pixel Extended 2.7)
device = Realme X (RMX1901)
1. I backed up all partitions (including system and vendor images)
2. installed Ancient OS rom for testing
3. removed that rom and tried to restore from backup
4. got error that user 10 could not be decrypted
5. from google searches, I tried to modify the copy of backup to remove 10 from user/, user_de/, etc., but had no fully compatible software in linux, so moved to other video
6. watched this "
" video, and deleted some key files in /data, except /data/media and the Android folder
7. flashed rom, rebooted, did not set password, back to TWRP
8. this step was to restore Data from /data/media/0, but all the folder names and files were encrypted
9. I cannot restore from backup of twrp backup because of editing of those files using incompatible software, nor am I able to copy it to the device, there is some libmtp error that doesn't allow that
10. realme x has no sdcard slot
Screenshot attached of the /data/media/0 directory at present
PLEASE HELP!
