Ok I ran a adb backup -all and after about an hour I ended up with a file about 10MBs in size
with adb backup -all -apk I end up with a 30MB file
What is going on here? what am I doing wrong. My 8 gig phone can't possible be being backup to such a small file can it?
Note this is not a NAND backup as I can not do that on my phone because of a locked bootloader, hence the reason I am trying to make these .ab backups cuz right now besides titan backup that is my only option.

I recently tried a new ROM and made a Rom Manager recovery restore file prior to changing. Things didn't work out as well as I had hoped and when attempting to restore, it fails at the checking MD5 sum process.
Any way to work around this? I really would like to restore to the previous ROM without starting over.
Anybody? I am not quite sure how the restore file can be created on this phone and then not pass verification?
Any ideas or am I stuck starting over?

depending on the type of file format used to backup, the restoring could be done manually but a changed md5sum generally means the files are not the same as the original. this could result in corruption and generally it isnt recommended to restore corrupted files as you run the risk of nothing working.
if you're still wanting to proceeding with attempting to restore files which are different than the original and could be corrupted, off the top of my head, you can probably dd the .img files back and untar the .tar files back.
i would suggest starting over and perhaps copying the backup files over to your desktop instead of only leaving on the sdard. this should help ensure at least one of the copies maintains their integrity.
hope that helps!
You can boot into recovery, and run nandroid via adb shell command line, no md5 checksum file needed. Now if the image is bad, you of course get bad results, but if the checksum is just hosed for some reason, it will work fine.
Put the .win files for the partitions you want to restore in /sdacrd
then issue the command "tar xvpf /sdcard/data.win" or "tar xvpf /sdcard/system.win" from the adb shell while in /data or /system respectively. .win files are what TWRP creates for backups.
I had this happen with TWRP 1.01 or 1.02 once on a good backup that passed the checksum tests when I backed it up.
I was testing the reliability of the TWRP package's nandroid and first one failed.
Once I moved to the newer version, I've not had that issue.
hey guys,
I have made a nandroid backup of my nexus 7 (2012) and I need to get access to contents of the data partition without actually applying the nandroid backup to the device. I found this "unyaffs" tool, but it requires .img files if I understood it correctly. However, in my nandroid backup directory, I have a couple of files that end in ".win" or ".win000" etc (along with corresponding md5-files)...these must be image files of some sort I guess, but Windows describes them as "Adobe CMS Extensions" for some reason.
So...anyone knows how I can access this data? Any help appreciated!
cheers

Hi folks. I took an adb backup (adb -d backup -apk -shared -all -f C:\Users\Tony\backup.ab) and now only want to restore data for a few apps.
I've used the Android Backup Toolkit to turn the .ab into an openable .tar file, so I tried copying a few com.appmaker.appname folders to the sdcard, then used Es File Explorer in root mode to copy the folders to /data/data, but the app doesn't seem to use the data (it looks like it did on first run).
Can anyone outline the steps required to restore data folders?
Thanks.
Tony.
I created a TWRP backup which was 17.1 GB in size, I've restored the file whenever the need arised but today when attempting to restore nothing would happen.
I have just realised the file has gone from 17.1 GB to 0 bytes it looks like the file has become corrupt or somehow it has been overwritten with a blank backup.ab is it possible to recover my file?
My OS is Windows 10 and would really appreciate any help if possible.
@AndroidOmenon
Windows 10 automatically creates backups of your files that allows you to jump back to older file versions, of course only if this option is not disabled.
@jwoegerbauer
Many thanks for your reply, I checked my computer for any available backups unfortunately I don't have any. The backup option was set to disabled.
Before you replied to my post I decided to try data recovery software, the file is found and shows as 17.1 GB but when recovered its only 518 bytes if I remember correctly.
I am hoping it will still be possible to recover the file someone may still be able to help me.
.I want to backup the gamesof my daughters phone with ADB. I activated USB-Debug and start backup with "adb backup -f [Name for the Backup].ab [PACKAGE_ID]"
After confirming the securityquestion in the phone backup starts and comes confirmation that backup is ready. In the ADB-folder on my PC I see a new wit the name of the backup, but it is only 1kb. When I make other backups they are also only 1kb.
Is this correct?
