Live ubuntu backup by billbear
This program will help you back up the running ubuntu system to compress the backup file into a startup squashfs.
Start the backup file and run the program again.
You can restore the backup file to another machine.
You can migrate ubuntu from a virtual machine to a real machine.
You can migrate the wubi-installed system to a real partition.
Installation:
You only need to copy the script to any place and grant the execution permission.
I like to put it in/usr/local/bin, so that no absolute path needs to be written every time I run it.
Usage:
Sudo path to this script-B
Is a backup, and
Sudo path to this script-r
Yes.
You can also use
Sudo bash to this script path-B
And
Sudo bash to this script path-r
Note that it cannot be used
Sudo sh path to this script-B
And
Sudo sh path to this script-r
Backup:
The program depends on squashfs-tools to work.
In addition, you must install lupin-casper to make a boot backup.
Run the following command on the terminal to install them:
Sudo apt-get install squashfs-tools lupin-casper
Then you can use this command to back up the running ubuntu system:
Sudo path to this script-B
If the script is in/usr/local/bin
Sudo lub-B
Then follow the prompts.
You can specify the backup storage path and the files and directories to be excluded.
You do not need to detach a mobile hard disk, windows partition, or any partition that you manually mount. They will be ignored automatically.
Therefore, you can directly store backups to mobile hard disks, windows partitions, and so on.
Be careful: Make sure you have enough space to store the backup.
The script will generate several other files required for startup.
Read the menu. lst generated in the backup storage directory, which will show you how to start the backup file directly.
Recovery:
Read the menu. lst generated in the backup storage directory, which will show you how to start the backup file directly.
After live ubuntu backup is started, open a terminal and enter
Sudo path to this script-r
If the script has been stored in/usr/local/bin during backup
Sudo lub-r
And restore as prompted.
Note: This script does not provide the Partition Function (you can only format but cannot create a partition, delete a partition or adjust the partition size ).
Only partitions that have been backed up can be restored.
Therefore, we recommend that you install gparted before the backup so that you can use the partition tool to recover the backup.
In addition, if an error occurs in the Partition Table, the backup cannot be restored until the error is fixed.
You can specify Several partitions and Their mount points.
If you do not have a swap partition, you can create a swap file for you (if you do ).
A new fstab is automatically generated and grub is installed.
If necessary, you can change the host name, user name, and password.
The backup system must be running.
Enter sudo lub-B as prompted.
Code:Ubuntu @ ubuntu-laptop :~ $ Sudo lub-B
Back up the system. We recommend that you exit other programs. Continue? (Y/n)

Specify an empty directory (absolute path) to store the backup. You can drag and drop the directory from the Nautilus File Manager to this point. You can use a mobile hard disk.
If this parameter is not specified, it will be stored in/home/ubuntu/backup-20090524
Specify the file/directory to be excluded and write one line. You can drag and drop this point from the Nautilus File Manager. End with a blank line.

Backed up to/home/ubuntu/backup-20090524. Please read the menu. lst in it :)
Let's look at the backup. In addition to the backup file itself, there are also kernels for Direct start:
Code:Ubuntu @ ubuntu-laptop :~ $ Ls/home/ubuntu/backup-20090524/
Backup20090524.squashfs menu. lst
Initrd. img-2.6.28-11-generic vmlinuz-2.6.28-11-generic
Let's see how to start the backup file-it's all written in the notes of menu. lst.
Note:
You can store all backups on a built-in hard disk for startup;
You can store all backups on the mobile hard disk and start them from the mobile hard disk;
You can also place the kernel on the built-in hard disk, squashfs on the mobile hard disk, and boot the kernel from the built-in hard disk to start the backup of the mobile hard disk)
Code:Ubuntu @ ubuntu-laptop :~ $ Cat/home/ubuntu/backup-20090524/menu. lst
# This menu. lst is for grub4dos. Can be used for gnu grub with slight modifications
# How to directly start your backup20090524.squashfs on a windows machine:
# Download the latest grub4dos from the http://download.gna.org/grub4dos
# Decompress the downloaded grub4dos and copy grldr and grldr. mbr to the c: root directory.
# Copy this menu. lst to the c: root directory.
# Then create a "casper" directory in the root directory of any partition and copy the backup20090524.squashfs, initrd. img-2.6.28-11-generic, vmlinuz-2.6.28-11-generic to it
# Add the following line of text to the end of boot. ini (not including)
# C: \ grldr. mbr = "grub4dos"
##### For Windows Vista, you can create a boot. ini file and write it as follows:
##### [Boot loader]
##### [Operating systems]
##### C: \ grldr. mbr = "grub4dos"
# Restart grub4dos.
# How to directly start your backup20090524.squashfs on a linux machine:
# Create a "casper" folder in the root directory of any partition (note gnu grub cannot read NTFS, so casper cannot be put there) and copy backup20090524.squashfs, initrd. img-2.6.28-11-generic, vmlinuz-2.6.28-11-generic to it
# Copy the following two Live Ubuntu Backup boot items to the end of/boot/grub/menu. lst and change the "find -- set-root" line to "root (hd ?,?) "(The partition where you created the" casper "folder)

To recover the backup file, it is best to start the backup file first. Restoring the backup in other environments is unpredictable. Of course, the same version of livecd should guide us to recover our backup theoretically. The following is the recovery operation (which can also be called installation) after the backup file is started)
Code:Ubuntu @ ubuntu :~ $ Sudo lub-r
