Retrying with the _correct_ address this time. *blush*

Hi,

I recently got caught out by the behaviour in rsync and 
am not sure if it is a bug or not.

I was running rsync like:

rsync -avz -e ssh --progress <source> <destination>

The source was a directory structure.  Partway through the 
transfer I stopped it with a Ctrl-c.  Later I ran the same
command again and it completed.

<Cut out irrelevant confusion here>

I did a checksum on the files in the source and destination
directories and the checksums on one of the files was different.
I think it was on the file that I stopped rsync on.
>From what I read on the manpage, I thought rsync was supposed 
to create a copy of the the source on the destination.  Is 
this not the case?

After testing a bit I found that adding the --checksum option
provided the behaviour I needed.  Can someone offer some 
enlightenment?

rsync version on source:
rsync  version 2.5.6  protocol version 26

rsync version on destination:
rsync  version 2.5.4  protocol version 26

Thanks for a great tool like rsync!

Most likely you hit a temporal window on the modification
time.  This was probably not related to the interruption.
