I run a web server on Debian-Lenny.
For the moment, I backup my whole system with tar with a daily script.
But for the recovery, I need to reinstall a clean Debian and then untar my latest tar file into the clean Debian and then I get my working system back.
Now, I would like to use a software like Ghost to backup my system daily.
If my system crashes, what I want is an usb key that I insert into my server with the latest image backed up from my server and I want to be up and running again.
