如何从计算机备份整个设备并在Linux中安装任何Bakup分区？ -- adb 领域 和 backup 领域 和 shell 领域 android 相关 的问题

I am looking for some tutorial or help to be able to make a backup of all Android partitions directly on my computer and be able to mount each of them from Linux to view them.

I don't know if it will work for your particular device and OS but I think this script is straight forward and you will be able to get the general idea and modify accordingly.

It first lists the content of /dev/block/platform/[xxxxx]/by-name directory (differs from device to device) then loops through the content files which in this case are partition names of your particular device. In each iteration it trims the 0x0d (carriage-return "\r") character that is added at the end of each file name, then it uses cat to print the partition to stdout of your terminal but we must also handle 0x0d (carriage-return "\r") byte that is added before newline(0x0a) before printing, then it calculates the md5sum of the output file which you can compare to the md5sum of the partition in your device to be sure there is no corruption.

#!/bin/bash BY_NAME_DIR="/dev/block/platform/sprd-sdhci.3/by-name" for partition in $(adb shell ls $BY_NAME_DIR) do             partition=$(tr -d '\r'<<<$partition)             echo Backing up $partition partition             adb shell "su -c cat $BY_NAME_DIR/$partition 2> /dev/null"|sed 's/\r$//' > ${partition}.img             echo Calculating md5sum              md5sum ${partition}.img > ${partition}.md5             echo Done backing up ${partition} done 

You can also refer to this question to see how you can handle the added "\r"(0x0d) characters
