most of the csync2 installations I did do not use SSL,
as they just go via direct link.
maybe someone else can give you some hints there.

"Error while backing up" ...

now, is it possible that you have a backup directory configured,
but that backup directory does not exist?

if so, just mkdir it.

what about

host2# touch "file I don't want to remove"
host2# csync2 -xv "file I don't want to remove"



SSL: I've tried with nossl once and it does the same thing as two 
identical ssl certificates. So I'm waiting for an answer for this, a 
configuration example or after the bug on debian.
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=501289

Error: Oh! you are right, I've forgot to mkdir my backup directory on 
the second host.
I suggest that the error:
ERROR from peer siduxbox: Open error while backing up 
'/backup/website/mont-laurier.local/Makefile': No such file or directory
should be rewritten with the final destination, not the source file:
ERROR from peer siduxbox: Open error while backing up 
'/var/backups/csync2/backup_website_mont-laurier.local_Makefile.0': No 
such file or directory

OK for the backup, I didn't think about the rotating archive.
If I want to do a script that automatically restore deleting file, I 
could do
1. select all file inside the database
2. if the file don't exists,
check in the archive ( sed 's#_#/#g' ) and copy it removing the .0

or
1. Check with database all files that don't exists.
2. Upload the list on the server side and touch the server file from the 
list
