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=192.168.0.100 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:
6 Restore Image/Install Image On A New System
On the image server, execute the following command:
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:
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 192.168.0.100
(Make sure your firewall allows connections to port 873!)
On the image server, run
si_getimage -golden-client 192.168.0.101 -image my_golden_client -ip-assignment replicant
8 Delete An Image
If you want to delete an image on your image server, simply run
(my_golden_client should be replaced with the name of the image to be deleted.)
