Can you explain what the '-' does there?  Is it a stand-in for a temporary 
file?  That can't be, because how would the temporary file get to the 
remote system?

These are great - thanks.  This is especially good since I'm beginning to
design some kind of 'backup' regimen.  I was planning to just write a
handful of scripts myself, but it occurs to me that there is probably some
kind of 'standard' tool that people use to perform routine, maybe
incremental, compressed backups.  Is there?  It seems like 'tar' is the 
right tool to me.
