    CM5系统修改了一些配置,想按照论坛里的双U盘(backup跟install)备份跟安装系统一直失败,备份U盘里读出来了数据,换到安装U盘里然后给其他板子无法安装系统

      这个最好使用移动硬盘备份,很多U盘在长时间大数据量写入的时候容易出错。这种情况之前也又遇到过。

          我们一直都是使用这个方法和脚本备份的,没有发现有什么问题的。你要做分区备份肯定不能在当前分区操作的。

            好的,谢谢
            不过我还是有几点疑问,首先我不懂您所说的分区备份是什么意思,还望您能虚心指导一下,或者有相关的资料查阅,还有就是我还是应该使用此方法进行备份嘛,只不过换成移动硬盘,因为我的系统有30个G左右,我使用脚本或者backup U盘备份出来的系统都无法正常使用,U盘备份出来20多个文件,大概30G左右

              你仔细看一下我们的那个脚本,实际上思路很简单,先dd一个img镜像(大于你的FS的大小),然后把这个镜像分为2个区(一个放boot,一个放FS),再然后把镜像挂载到系统,再把系统对应分区直接复制到镜像分区,然后做一些文件系统检查的工作即可。

                @george 我新买了移动硬盘,但是RUFUS识别不到硬盘,没办法安装备份系统,然后我用u盘安装备份系统,再拷贝到硬盘里去,无法识别硬盘的系统。

                  先把硬盘格式化为EXT4或者NTFS格式,然后就可以正常识别了。

                  sudo mkfs.ext4 /dev/sd*
                  或者
                  sudo mkfs.ntfs /dev/sd*
