RDK X5 镜像备份（详细）

前期准备

1 准备读卡器和SD卡

新 SD 卡好像默认是 ext4 格式

2 接入RDK X5

3 查看SD卡显示

新插入的SD卡显示在 /media 路径下面，但在 /mnt 路径下没有

关键步骤

ubuntu 下ext4格式挂载磁盘

sudo mkdir mnt/mytext
sudo mount /dev/sda1 /mnt/mytext/
df -lh

参考文章：Linux (ubuntu18) 下ext4格式挂载磁盘

官方教程

参考官方教程：rdk-backup命令 用于将当前系统备份成镜像。

注意给路径就行！！！

sudo rdk-backup /mnt/myext

成功备份（ 终端输出 ）

保存的文件名称格式： rdk-年月日-时分.img

sunrise@ubuntu:/mnt$ sudo rdk-backup /mnt/myext
mount_dir: /mnt/myext
