Hi All,

I am trying to understand the purpose of rsyncd. Why does it exist?
Why not just use rsync ad-hoc or via script?

Also, to a more serious note. I need to keep a filesystem on 1 server
and another server synced by.
What is the best way to do this? I want to have /source and /target to
be exactly the same. I don't want any extra files in /target. I want
the timestamps to be the exact same in /target. Does anyone have a
good rsync arguments I can use? I have been using -avzl but I was
wondering if there was anything better.
