i would like to backup my dedicated server which is my web server hosting various sites and email, so that I can update the os to Ubuntu 12.04, and basically restore back to 10.04 if things go wrong. I have a local machine that I can install 12.04 onto an then I was going to rsinc between the two, but I am fairly clueless when it comes to linux. I can ssh into the remote server and gain root access. can anyone explain if i need to backup the whole server hard drive or just some of the files? Thanks Timmo.
