[ubuntu-uk] backup home folder

[Norman Silverstone]

I frequently read that, before carrying out various operations, one
should first backup the home folder. Does this mean simply taking a CD
and copying the home folder to it?

Assuming that this is correct does it mean that if I mess things up or
even have to re-install Ubuntu from scratch, copying this home folder
back into the new installation will restore such things as my email
address book and stored emails, for example?

Please advise this overcautious person.
