rsync -

[Bob Goodwin]

I have two f-10 desk top computers, boxes 6 and 9. I use them 
interchangeably and keep notes [notecase] in both. I would like to 
update each from the other without losing anything in the process.

The name "rsync" seems to imply that it will make them identical. Does 
that mean if the source has fewer files than the target the target will 
have some deleted? Is there a command string to ensure I wont lose 
anything?

None of this is clear to me from the man page.
