So I have gddrescue installed and I am trying to figure out what signifies the entire contents of the harddrive. Now the syntax:
ddrescue /dev/<partition_to_backup> filename.iso
First, what does /dev signify? If it means root, what specifies everything in it? I am a Linux newb obviously.
I want to make sure that whatever back up I create, is able to be put on a new ubuntu install and all applications etc can be used and configured identical to how this install is.
