[BackupPC-users] Backing up localhost nfs share with rsync

hi,

I know this subject is sometime talked about but searching the list do not helped, a lot of testing neither so i try here in the hope someone will be able to help me.

I try to backup a nfs mount share, for that i mount it on the backuppc server so i can backup it without using a silly

backuppc -- ssh --> server web => nfs => server web ----ssh --> backuppc

   loop and clog the network for nothing

   So i used this:

----------------------------------------backupserver.mydomain.com.pl-------------------------------------------- # include default config do '/etc/backuppc/config.pl'; # # Path to rsync executable on the client # $Conf{RsyncClientPath} = '/usr/bin/sudo -n /usr/bin/rsync'; $Conf{XferMethod}       = 'rsync'; $Conf{RsyncShareName}   = ['/']; # rsync client commands $Conf{RsyncClientCmd}           = '$rsyncPath $argList+'; $Conf{RsyncClientRestoreCmd}    = '$rsyncPath $argList+'; # repertoires a backuper $Conf{BackupFilesOnly}    = {         '/' => [ '/etc','/var/www' ], }; # repertoire a exclure $Conf{BackupFilesExclude} = {         '/'     =>      [ '**/archive/**' ], }; -------------------------------------------------------------------------------

have the error "Fatal error (bad version): Exec failed for /usr/bin/sudo -n /usr/bin/rsync..." :

(root)> sudo -u backuppc /usr/share/backuppc/bin/BackupPC_dump -v -f backupserver.mydomain.com

...snip....

full backup started for directory / (baseline backup #8) started full dump, share=/ Running: /usr/bin/sudo\ -n\ /usr/bin/rsync --server --sender --numeric-ids --perms --owner --group -D --links --hard-links --times --recursive --checksum-seed=32761 --protocol=28 --ignore-times . / Xfer PIDs are now 16249 xferPids 16249 Got remote protocol 1667594309 Fatal error (bad version): Exec failed for /usr/bin/sudo -n /usr/bin/rsync --server --sender --numeric-ids --perms --owner --group -D --links --hard-links --times --recursive --checksum-seed=32761 --protocol=28 --ignore-times . /

i have my sudoers to:

# Cmnd alias specification Cmnd_Alias      BACKUPLOCAL =               /usr/bin/rsync,\                                              /bin/false # User privilege specification backuppc    ALL = (root)        NOPASSWD:       BACKUPLOCAL

   the proces of backuppc works on the right user:

backuppc 13791 0.0 0.0 63452 13432 ?        S    09:25   0:01 /usr/bin/perl /usr/share/backuppc/bin/BackupPC -d
backuppc 13793 0.0 0.0 43948 7020 ?        S    09:25   0:00 /usr/bin/perl /usr/share/backuppc/bin/BackupPC_trashClean

and command line works well:

(root)> sudo -u backuppc /usr/bin/sudo   /usr/bin/rsync --version rsync version 3.0.7 protocol version 30 Copyright (C) 1996-2009 by Andrew Tridgell, Wayne Davison, and others. Web site: http://rsync.samba.org/ ....snip....

i have tested quite a lot of configuration but i really do not find where the problem is. I tried to add --protocol=28/29 to rsync but no change to the result so far. Any ideas on how to debug this ?

best regards,
Ghis
