Bonjour, of course I know ;-)

Thanks, that what I wanted to know, so I keep them all.

I fully agree but I don't like long options ;-p

Of that what it should do! But I'm sure not: the target is a very 
low-quality-and-performance USB key. I had to do it on another computer witch 
write on it a little less slow, otherwise I would have last forever with less 
than 3 kb/s. And looking the FS during the transfer, I saw the temporary files 
being written. And since I was using --backup, the files has been backuped... 
only to be replaced by exactly the same thing :-(

So this disable a lot of interest in Rsync :-( Isn't there a way to disable 
"--whole-file"?

Even if, I must admit, the source problem is the changes in timestamps. It's a 
mystery, it seems that there was an exact one-hour difference each time. So I 
suppose it's related to timezone, but how can this be? Is it the fact that the 
source is in Vfat(but almost always used under GNU/Linux) and target in Ext2? 
However, "date -r {file}" was saying "GMT+2" in both cases... I don't know and 
don't have time to investigate on this.

Another strange thing, regarding this mailing list this time: I'm subscribed in 
digest mode, but this doesn't prevent some mails to be missing. For example, in 
the thread "copy to destination only new files" one week ago, I got the two 
from SE at SHCH262.com but not the one from Robin Lee Powell
