Howto: Backup and restore your system!

[psusi]

It means what it says; there were previous errors. So read what it said previously for details.

Does this not leave a lot of junk on the system? I want to copy a Ubuntu installation to another computer. I freshly installed the other PC, but there is still a lot of junk of uninstalled apps (e.g. Rythmbox, Totem)

I have created three separate backups using the method in the first post. Backed up to separate partitions (excluded all other mounted devices) and have not been able to restore the backup on any occasion.

For example, backed up Ubuntu 9.10 to the external partition (tar cvpzf /media/Linux_Backup/2010Mar10backup.tgz --exclude=/proc --exclude=/lost+found --exclude=/backup.tgz --exclude=/mnt --exclude=/sys /). Unmounted all unnecessary volumes.

Installed Ubuntu 10.04 as an upgrade, then decided to restore 9.10 with
tar xvpfz /media/Linux_Backup/2010Mar10backup.tgz -C /. The restore failed as all other attempts.

What am I missing?

sudo?

To make the backup have a date extension, you might want to check out this script which I am now using as it does everything I need.
http://ubuntuforums.org/showthread.p...pt+run+nightly
The section that you need is this bit:

# Create archive filename.
day=$(date +%a)
time=$(date +%R)
hostname=$(hostname -s)
archive_file="$hostname-$day-$time.tgz"

Hi...

Please tell me, I've done a backup as mentioned on the first post.
Now I want to restore everything, but I want the process to delete files that were made after the first backup. I want a clean system. When I do the restore, it says "tar: Exiting with failure status due to previous errors" and that's just it... All the files added after the backup are still there.

Can I use this method to backup everything from my 32 bit 9.04 to 64 bit 9.10?
I am going to install fresh 64 bit 9.10 to new hdd.
My current hdd have 32 bit 9.04.
Anyone had already done like this?
Will it cause any problem? damage? compatibility issue etc?

This question does not make sense. You backup from one disk to another, not from one version of the OS to another.

Thank you so much for this tutorial.
I was trying to repair my grub for the past few days and was really frustrated.
None of the suggested method works.

When I tried method two, posted my remmelt, the terminal just replied:
/
The program 'grub' is currently not installed. You can install it by typing:
sudo apt-get install grub
grub: command not found
/

I don't have internet connected to my computer (the one I am trying to repair), what should I do?

I can use the command "grub-install" though. However, when I tried the method provided by rpakdel
(the 4th method), the terminal tells me that it can't do that:

me : mkdir /ubuntu
me : mount /dev/sda /ubuntu

system:
/dev/sda already mounted or /ubuntu busy


me : grub-install /dev/sda

system :
/usr/sbin/grub-probe: error: cannot find a device for /boot/grub (is /dev mounted?)

What should I do? I really need to repair it!
