In this instance, it's a one-off, manual thing, in preparation to 
flattening and reinstalling the machine, or at least I *think* that's 
what Glenn said.

As a side note, that's true even if the root account has no password 
- Glenn can put a public SSH key into the /root/.ssh/authorized_keys 
file (or copy a public key there if it doesn't exist) using the sudo 
method, and then the account owning the private key can ssh in as 
root.

Of course, your comments in general are spot on in terms of ongoing 
backup.
