The Ubuntu system is backed up to the mobile hard drive (tar) and restored to another computer.

System Version: Ubuntu 13.04 32-bit

1. Open your mobile hard disk in the desktop environment

View disk drive: df-ah

Df (DiskFree) a represents all, and h Represents characters that human can understand. For details, see command df -- help.
Www.bkjia.com @ linux:/dev $ df-ah

I want to put the backup file in ly1. So remember the device sdb1

2. Start in command mode (refer to the link)

Command:

Sudo gedit/etc/default/grub

Find this line

GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash"

Change

GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash text"

Enter the following command:
Sudo update-grub

After the device is started, it automatically enters tty1.

Mount after login:
Www.bkjia.com @ linux:/dev $ sudo mount sdb1/media/ly

3. Use tar backup (refer to the link)

1) become the root user: sudo su

1-1) Change grub to desktop startup

Sudo vi/etc/default/grub

Find this line

GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash text"

Change

GRUB_CMDLINE_LINUX_DEFAULT = "quiet splash"

Enter the following command:
Sudo update-grub

2) go to the root directory: cd/

3) tar-cvpjf/media/ly/ubuntu1304_bkp.tar.bz2 -- exclude =/proc -- exclude =/lost + found -- exclude =/mnt -- exclude =/sys -- exclude =/media/

..........

Wait patiently.

The system has been backed up.

Note:

1) tar backup can also be used without starting in command mode (directly go to the console ctrl + alt + F1), but an error will be reported at the end, saying ".... preview failure ...... "You cannot remember. I do not know whether the backup file can be used after restoration. I have not tested it. Therefore, it is safer to start the service in command mode.

2) using Live CD (or Live USB) for backup is simpler and safer. (Reference: Click to open the link)
