Ok, thanks for your informations Toni.
It's nice.
For the moment I can connect to the BackupPC server (via SSH) from the
Windows client but I can't do the reverse.
When I try to do a Backup via "rsync" :
=================================================================================================================================================================
Fichier /data/BackupPC/pc/vsds-mov-w0316/XferLOG.bad.z
Contenu du fichier /data/BackupPC/pc/vsds-mov-w0316/XferLOG.bad.z, modifié
le 2007-10-05 14:21:59
full backup started for directory /c/test (baseline backup #58)
Running: /usr/bin/ssh -q -x -l root vsds-mov-w0316 /usr/bin/rsync --server
--sender --numeric-ids --perms --owner --group -D --links --hard-links
--times --block-size=2048 --recursive --ignore-times . /c/test/
Xfer PIDs are now 3770
Read EOF: Connexion ré-initialisée par le correspondant
Tried again: got 0 bytes
Done: 0 files, 0 bytes
Got fatal error during xfer (Unable to read 4 bytes)
Backup aborted (Unable to read 4 bytes)

When I try to do a Backup via "rsyncd" :
=================================================================================================================================================================

full backup started for directory /c/test (baseline backup #58)
Connected to vsds-mov-w0316:873, remote version 29
Negotiated protocol version 28
Error connecting to module /c/test/ at vsds-mov-w0316:873: Unknown module
'/c/test/'
Got fatal error during xfer (Unknown module '/c/test/')
Backup aborted (Unknown module '/c/test/')
=================================================================================================================================================================
Have you got some explanations ?
Thanks for your help.

This is how I add a ssh-based client to my backup system:
* On the backup server, the user backuppc generates a ssh-key
(ssh-keygen -t rsa -f clientname) inside .ssh of the backuppc home
directory. Passphrase is empty.
* On the backup server, the file .ssh/config belonging to the backuppc
user is updated with some needed info for the client (user to connect,
ssh-key to use, port to use, ...)
* The key is copied to the client (ssh-copyid -i clientname.pub
client.domain.com) This action will ask if you trust this host. Answer
'yes' to add it to the know_hosts list.
Finished. The user 'backuppc' has now root access to the client through
SSH. Setting up BackupPC is now the most easy part: use rsync, set the
clients directories to backup. Done.
Why do I use a separate key for every client? Security! If someone can
get 1 private key from my backup server, he/she can only connect to 1
client instead of all my clients (70 at this moment).
Yes it is a bit more work, but security is always more work.
Good luck.
