I am using the latest version of adb with the pull command to backup my data.

Sometimes adb pull doesn't backup all of my files, so I am trying to figure out which files have not been backed up.

Using adb logcat -f logcat.txt bugreport pull "my path" "my path 2" just throws me a create bugreport fail! and create bugreports dir error!!. I've tried multiple directories with full permission but with no luck.

If you want to execute an adb pull comand and at the same time monitor the on-device log via adb logcat you can do so by executing each command individually in it's own terminal/cmd.exe instance.

adb is not limited to a single connection (as the MTP protocol is). Hence you can execute two or more adb command simultaneously. Even multiple adb push or pull commands can be executed at the same time.

However I doubt that doing so will get you much insight regarding your problem with adb pull that some files are not copied via adb pull. The main problem is that adb logcat just displays the log of your device. All errors on adb level, for example if a file could not created on your PC or transmission problems between device and PC are not covered by this log as the device does not know about them.

Additionally I am not sure that the on-device adb daemon writes messages to the logcat log at all.

  • I wasn't aware of logcat and pull being two different commands. My bad. – computationalprince May 24 '20 at 11:27

    @computationalprince adb can be seen as some sort of ssh connection that connects to the device and executes commands commands on-device (e.g. logcat is simply a binary that is executed on-device). Only in case of file transmissions some additional logic (pull/push/install) for the file transfer is executed by adb itself. – Robert May 24 '20 at 11:32
