Linux系统备份恢复工具SYSTEM-RESCUE-CD的使用

测试系统：linux-debian

备份系统1、插入dd有systemrescuecd-x86-4.0.1.iso的系统备份恢复U盘；2、开机按DEL进入BIOS，设置BOOT为USB-HDD启动。Save&Exit；3、进入备份恢复系统界面：	--------------------------------------------------------------------	     	|

挂载U盘分区:    mount /dev/sdb2 /mnt/floppy    或直接在U盘目录中赋予一个目录读写权限:    mount -o remount,rw /livemnt/boot/6、 创建镜像：partimage
