I'm going to be sending in my laptop for a repair (damaged touchpad) and the company warned me to backup my data and system since they are not responsible for damages. I've done some google searches but all the articles tell you to use Windows backup tool but I don't have a Windows Home CD to install it from (wither lost it or never got one), I have plenty of external space to backup the whole drive on but how would I do it with out the Windows Backup tool?
