How do I mount External Hard Drive and what command to backup Home Folder to it ?
 
Hello:


On ubuntu 10.10 notebook edition, that won't boot due to /sbin/init being damaged, how would I mount the External Hard Drive and then what command would I use to backup my Home Folder to External Hard Drive , using live CD?
I am hoping to salvage my Home Folder and then do a Re-install of my ubuntu 10.10 notebook edition.

Using Live CD when I go to my home folder, I can see all the partitions on the old system and their size, but how would I back up the Home Folder to the external HD?

The external hard drive should be auto-mounted by the live cd.

To mount the partition in which resides your home folder, the command line is your friend:

1) first you have to create the directory that you'll use as mount point:
Code:

sudo mkdir /media/mypartition
2) then, mount the partition in which resides your home folder (let's say /dev/sda1)
Code:

sudo mount /dev/sda1 /media/mypartition
4) copy to the external hard drive.
For example:
Code:

cp -R /media/mypartition/home/yourusername /path/to/external/hard/drive
If you want to do things graphically, you can open nautilus in the home folder of the mounted partition:

Code:

$ cd /media/mypartition/home/yourusername
$ nautilus .

Hope these help.

Ok, I performed all the above commnads in the terminal.
But it didn't work. I couldn't copy to mypartition directroy. I suspect has to do with the fact that my External Usb Drive is an NTFS file system?

Exactly, what happens? performing the commands results in error messages?

(ps don't forget to unmount with the umount command)

Probably not but it isn't a good idea to copy directories/files from a Linux filesystem to a windows filesystem. I wouldn't expect anything but trouble from it.

I would suggest that if you are doing this from an Ubuntu CD, you run the sudo fdisk -l(lower case Letter L in the command) and post that drive/partition information here. If your external is auto-mounted it probably is in the /media directory with a UUID number. You will need to create a mount point for your external partition if you are going to use a terminal to copy to it. Post the fdisk output.

ghoultek 09-30-2011 06:38 PM

Try doing the following:
- Boot your laptop with the LiveCD
- Once you are at the desktop, connect your external hard drive to your laptop
- Start a Terminal window

In the following order:
- Type lsusb
- Type su (this should get you root access)
- Type fdisk -l
- Type mount
- Type cat /etc/fstab

Post the results of those commands.

Update: I tried sudo on my fresh Slackware v13.37 install when logged in as a regular user (non-root and non-super user) and it gave me an error message stating that my regular user account is not in the sudoers file. However, su just asks for the root password if I boot into Slackware. If I boot a Knoppix v6.7.1 LiveCD su doesn't require a password for root. I suspect the Ubuntu LiveCD may not require a password for su. If sudo doesn't work try su.

Larry Webb 09-30-2011 08:10 PM

OP is using ubuntu and for root access he should be using 'sudo' to start his command lines. With the live cd he will not be asked for a password.

yancek is right and all we need is the uuid and the following should solve all.

Your commands are wrong. Something like this would be better:

mkdir /mnt/extdrive
mount /dev/sdb1 /mnt/extdrive
# check that /dev/sdb1 is mounted
mount
mkdir /mnt/tmphome
# you need to get the right partition to mount the home directories
mount /dev/sda???? /mnt/tmphome
# check that tmphome is mounted
mount
cp -a /mnt/tmphome /mnt/extdrive

This is for if /home is on its own partition. If it isn't, your cp command should be more like this:

cp -a /mnt/tmphome/home /mnt/extdrive

And your 'cp' command won't get all the hidden files and directories either. I recommend the OP use 'tar' in order to backup the contents of the home directory.

Sure use tar if you want. But cp -a does copy hidden files and directories. Test it if you don't believe it.

The problem now is, which of the seven Linux partitions contains your home directory? You can eliminate sda1 as it is too small to be anything but a boot partition. sda2 is your Extended partition which contains no data and sda10 is swap. Do you have a separate /home partition or is it in your / partition? Why all these partitions if you only have Ubuntu? or do you?

The /etc/fstab file you posted is from the Live Cd and doesn't give any useful information.
Do you know where your /home directory is? on a separate partition? the / partition? do you know which partition that might be? If not you will probably have to try creating a mount point for each, mount each partition until you find your /home directory.

Repeat this process for each partition until you find it, partitions 5 - 11 (excepting 10 - swap) unless you know which partition it is??

sudo mkdir /mnt/sda5
sudo mount -t ext4 /dev/sda5 /mnt/sda5

After doing the above, you can navigate to the /mnt/sda5 partition to see if your /home is there: ls /mnt/sda5

You could also open nautilus file manager, sudo nautilus.

This was our first school assignment, to create so many partitions manually, so to learn how manual partitioning works in Linux. I have two other Linux machine as part of a small network, which I let Linux do the partitioning for me. It was very simple. One is Ubuntu server 10.04 , the other is ubuntu 10.04 desktop.
So my /Home partition is the one which is 13 GB in size. (/dev/sda11 )

(It includes /root and /mansour )
When I go to Places ==> Home ==> I see all the partitions in the left pane. The 13 GB partition is /Home.

I can mount them all by right clicking on them and then choosing mount from the menu.

/dev/sdb1 is my USB Hard Drive.( 1 TB and is NTFS)
OK, I see a file was transfered to my USB HD called FreeAgentGoNext.ico
That's the name of my HD backup software.
I safely removed it from my notebook and put it on the ubuntu 10.04 desktop machine.
How would I be able to read them there though?
I mean FreeAgentGoNext.ico, what would I do to transfer this to the /home folder of ubuntu desktop machine?
Please help here.
