Quelques soucis avec Backup Manage

bonjour à tous et à toutes,

Je me bagarre depuis quelques temps avec mes sauvegardes. J'aurais bien écrit un truc bien à moi, mais je suis une quiche en programmation. En déséspoir de cause, je me suis rabattu sur Backup Manager.
Je voudrais sauvegarder mon home et /etc (classique).
J'ai lancé ma sauvegarde et Backup manager me répond :

Impossible de créer « /home/SVG/alain-netbook-home-alain.20111206.master.tar », lisez /tmp/bm-tarball.log.FJ7zYd pour les détails.
Une erreur a eu lieu pendant la génération des archives.

Le fichier log me donne ça :

/bin/tar: Suppression de « / » au début des noms des membres
/bin/tar: /home/alain/.local/share/Trash/files/alain-netbook-home-alain.20111206.master.tar.gz : fichier modifié pendant sa lecture
/bin/tar: /home/alain/.gvfs : la fonction stat a échoué: Permission non accordée
/bin/tar: /home/alain : fichier modifié pendant sa lecture
/bin/tar: Arrêt avec code d'échec à cause des erreurs précédentes

Mon fichier de conf est le suivant :

#  Backup Manager Configuration File
#
#  * This configuration file is divided into sections.
#    The 'global' section is mandatory, every keys defined in 
#    this section are inherited in the other sections.
#  * There is one section per "backup method", you have to 
#    fill the section of the chosen method.

# If you want to encrypt your archives locally, Backup Manager

# You will then need to fill the BM_UPLOAD_SSH variables 
# (BM_UPLOAD_SSH_HOSTS, BM_UPLOAD_SSH_USER, BM_UPLOAD_SSH_KEY).
# If this boolean is set to true, archive will be saved locally (in

# Targets to backup

# You can use two different variables for defining the targets of 
# your backups, either a simple space-separated list (BM_TARBALL_DIRECTORIES)
# or an array (BM_TARBALL_TARGETS[]).
# Use the first one for simple path that doesn't contain spaces in their name.
# Use the former if you want to specify paths to backups with spaces.

# It's recommanded to use BM_TARBALL_TARGETS[] though.
# Warning! You *must not* use both variables at the same time.
# NOTE: The Debian package will only update BM_TARBALL_DIRECTORIES 

# Paths without spaces in their name:
export BM_TARBALL_DIRECTORIES="/etc /home/alain"

# If one or more of the targets contain a space, use the array:
# declare -a BM_TARBALL_TARGETS
# BM_TARBALL_TARGETS[0]="/etc" 
# BM_TARBALL_TARGETS[1]="/boot"

#############################################################

# The "pipe" method is a generic way of making archive.
# Its concept is simple, for every kind of archive you want
# to make, you give: a command which will send output on stdout,
# a name, a file type and optionnaly, a compressor. 

# Be careful, this feature uses arrays!

# You can virtually implement whatever backup scenario you like 
# with this method.
#
# The resulting archives will be named like this: 
# $BM_ARCHIVE_PREFIX-$BM_PIPE_NAME.$DATE.$BM_PIPE_FILETYPE
# If you specified a BM_PIPE_COMPRESS option, the resulting filename 
# will change as expected (eg, .gz if "gzip").
#
# Here are a couple of examples for using this method:

# Archive a remote MySQL database through SSH:
#    BM_PIPE_COMMAND[0]="ssh host -c \"mysqldump -ufoo -pbar base\"" 
#    BM_PIPE_NAME[0]="base" 
#    BM_PIPE_FILETYPE[0]="sql"
#    BM_PIPE_COMPRESS[0]="gzip"
# This will make somthing like: localhost-base.20050421.sql.gz

# Archive a specific directory, on a remote server through SSH:
#    BM_PIPE_COMMAND[0]="ssh host -c \"tar -c -z /home/user\"" 
#    BM_PIPE_NAME[0]="host.home.user" 
#    BM_PIPE_FILETYPE[0]="tar.gz"
#    BM_PIPE_COMPRESS[0]=""

Enfin, la taille de mon archive est de 38Go alors que mon home ne fait que 29Go. Je sais bien que c'est crétin de sauvegarder /home/alain sur /home/SVG, mais pour les tests, c'esst sans doute ce qu'il y a de plus rapide. Quand ce sera réellement au point, je ferais ces sauvegardes vers un disque externe qui lui même sera mirroré sur une autremachine

Ma tuile du jour est en plusieurs niveau :
1. Je trouve la sauvegarde longue et le niveau de sauvegarde ben...
2. Quel extension de fichier prendre pour faire cette foutue sauvegarde ?

d'avance merci pour votre aide

Je déterre un sujet vieux de deux ans, pardonnez moi. Si entre temps tu as trouvé une explication, je suis preneur, merci

Re : Quelques soucis avec Backup Manage

J'ai contourné le problème : je fais mes sauvegardes avec un script utilisant rsync. Désolé de ne pas pouvoir t’aider plus que ça.
