rsync - Dec 2003 - Change one file, and they all get sent!

Hi,

Just starting out with rsync, and I think I might be missing a 
fundamental point of how it works.

Scenario:

I start an rsync daemon on host A, and define a module 'test' on the 
rsyncd.conf file. 'test' is essentially my home directory on host A

I then sign on to host B and issue

rsync --progress --recursive --links --stats arthur::test/ /var/tmp/haggis

This copies 'test' from host 'arthur' (host A)  into 
/var/tmp/haggis
(on host B)

so far so good. Everything goes to host B no problem.

Next I edit a small file in 'test' on host A, then reissue the rsync 
command above. All files are checked and transferred according to the 
summary at the end. Am I incorret in assuming that only the delta of the 
before and after of the one small file I edited would be sent, rather 
than the entire directory tree defined by 'test'?

Remember, I'm using rsync to copy  *from* a host running an rsync 
daemon...would this be the issue?

Confused and probably missing something simple .... any ideas?

Thanks!

Scotty

Is either box Windows?  When I used an NT4 server as my rsync server, I 
had to use --modify-window 2 on the client side to get it to NOT copy 
over all files.

You didn't use -t to tell it to preserve the file times.  Without that,
you must use -c to checksum the files to figure out if they need to be
resent or not (which is much slower than just using -t).
