Wow. it's been so long.
I had an issue with this
cp --preserve -R \
/{bin,dev,home,pentest,root,usr,boot,etc,lib,opt, sbin,var} /mnt/bt/
In the notes. I changed it to
cp --preserve -R /{bin,dev,home,pentest,root,usr,boot,etc,lib,opt, sbin,var} /mnt/bt/
(THIS IS ONE LINE!!!!!)
and it worked after that. Not sure what that extra SLASH is \
