How To Back Up An Ubuntu 8.10 System With SystemImager - Page 2

5 Create A Boot CD

SystemImager lets you install images on systems that have nothing installed on it. But we have to tell such a system where to get the image from. This can be done with a boot CD. To create the boot .iso image (which you can then burn onto a CD), run the following command:


si_mkautoinstallcd -append "IMAGESERVER= IMAGENAME=my_golden_client" --out-file /home/administrator/image.iso

Please fill in the correct values for the image server and the image name and specify an output directory of your choice in --out-file.

You will be asked for a "flavor". Please type in the name of the golden image:

Here is a list of available flavors:


Which flavor would you like to use? [standard]:
 <-- my_golden_client


6 Restore Image/Install Image On A New System


On the image server, execute the following command:

/etc/init.d/systemimager-server-rsyncd start

Be sure that port 873 TCP can be accessed from the outside (firewall!).


Now insert your boot CD into the system and boot from it. Your new system will install the image my_golden_client automagically, and you are done!


After the image has been successfully restored, you can stop rsyncd:

/etc/init.d/systemimager-server-rsyncd stop 


7 Update An Image

Let's say you have made some important changes to your golden client, and now you want to update your previously created image my_golden_client. The steps are the same as in chapter 4:


On the golden client, run

si_prepareclient --server

(Make sure your firewall allows connections to port 873!)


On the image server, run

si_getimage -golden-client -image my_golden_client -ip-assignment replicant


8 Delete An Image


If you want to delete an image on your image server, simply run

si_rmimage my_golden_client

(my_golden_client should be replaced with the name of the image to be deleted.)

No, they are not. Please take a second look.

Aren't figure one and figure two on page one identical?  I see no relatime in line six of figure one.

Wouldn't it just be easier to use Clonezilla Live?



Since CD/DVD-players, due to their size,  are a little bit inconvenient to handle, I would love to read a "How To" made for booting a USB flash disk as well.


Well, I tried clonezilla, and a few other "image" backup software, and they all failed to re-size the partitions during a restore. The only software I found that did a good image backup/restore was Acronis TrueImage. It has full network support, and I was able to backup my Perfect Server/Ubuntu 8.04/ISPConfig/Ventrilo/Dyndns/PHP, etc from a 40GB drive to an image on a Windows machine, and then restore it to a 80GB drive and automatically restored everything to the 80GB drive, using all the available disk space.

 Most of the image backup tools for Linux seem to want exact disk-disk copies (same size), or restore the original image with only original disk space allocated (ie restore 40GB to 80GB drive, but Ubuntu only sees the 40GB ext3 partition- rest is unused). Being somewhat green to Linux, I just didn't want to play around with partition resizing on a working system

I have not tried systemimager as noted in this howto, but will someday - If it works, great. But if you can find a copy of Acronis, try it. I believe they may even have a 15 day trial demo (has to be installed on Windows - then make a boot CD. Boot CD is Linux based anyway) I'm not trying to promote it or anything, just my relate my experience on finding something that would do a full image restore that worked for me..

 Thanks Falko for all your help in these forums...
