(As there were no other replies) - there's nothing wrong with the
example - I often want to copy something somewhere else to the directory
I am in now.  I would also add -P to give me partial files (i.e. resume
midway through semi-transferred files) and a progress meter, and -v for
verbose output if I was running interactively.  Give it a try.

You can also specify "-e ssh" if the remote side supports login via ssh
- which keeys your details lovely and private.  the -e means 'this
  shell', so if ssh is running on a diferent port, it is legal to say :

     ...   -e "SSH -P 222"

I would start with an empty local directory so that the --delete was not
needed personally.

need to in order to get your backups working though.  I tend to use
rsync rather than scp for copies because rsync has had resumes for
longer .. but they are similar in interface behaviour, really.
