I've got the same error with different folders:

'/data/user/999'
'/data/misc_ce/999'
'/data/system_ce/999'

if they are unnecessary files I could delete them and try again.
does anyone know if these 999 folders are important?

also in my twrp the listed folders above look kind of encrypted (had some struggle with the oos5 update before), but in my file explorer they look decrypted.

are there some ideas what I should do?

looks like it's an error with parallel apps oder multiple users. since i do not use something like that, i just removed this user with the android terminal emulator:

su
pm remove-user 999

everything was fine after that

In my case i made a parallel app (facebook). So the backup failed every time. I killed the app and there is a folder called "999" in the internal storage. Delete it and the backup will work.

I did that, still doesn't work.

 

[krumbman0wnz]

I did that, still doesn't work.

you need to turn off parallel apps, then go into a root explorer and delete

data/system/999
data/system_ce/999
data/misc/999
data/misc_ce/999
data/user/999
data/user_ce/999

This will allow you to do a backup, but you'll get "extractTarFork() process ended with ERROR=255' when trying to restore. So it feels kind useless, unless someone can figure this out.

You need to delete those folders even before restoring a nandroid backup. At least worked for me

 

[more_than_hater]

oh, well, its kinda bad for me cuz i'm allmost at OP situation right now.
So, using 8.61 blue sparks twrp i made full backup of my partitions and got '' extractTarFork() process ended with ERROR=255 '' when i was trying to restore backup. Any idea, how can i restore my backup now?

From twrp go to advanced then filmanager. U have to delete all those 999 folders then u can restore

 

[more_than_hater]

There is no such folders at /data folder, only media and lost+found

Any idea?

looks like it's an error with parallel apps oder multiple users. since i do not use something like that, i just removed this user with the android terminal emulator:

su
pm remove-user 999

everything was fine after that

Thank you very much. Worked like a charm. Thanks a bunch.
And i second that the culprit here is folder 999 of parallel apps as i found facebook data from second account in this folder like profile pics etc.

Worked for me on 8.0! Thanks!

I've tried removing all 999 folders prior to backup, but it still fails. I'm rooted on 5.0.4. with magisk.

Anyone?

I could resolve my nandroid /data backup error on my EMUI 8.0 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 device.
I post on this forum because I hope that this will be helpful for others devices owners.

Thanks a lot for this! Helped me with OOS 9.5.4 on OnePlus 7 Pro.
