How to copy a whole directory (and all of its content recursively) over USB with adb pull
? For instance to backup the SD card.
Attempt:
$ adb pull /sdcard backup
failed to copy '/sdcard' to 'backup': Is a directory
The trick is to add /.
to the name of the folder you want to copy:
adb pull /sdcard/. backup
This copies the whole directory recursively.
