Problème mondo debian

Bonjour,
Je voudrais recréer une image de mon serveur sous debian à l'aide de mondo.

J'ai pu en faire une il y a 3 semaine environ mais depuis hier lorsue je lance mondo il m'affiche cette erreur :

# mondoarchive
Initializing...
Execution run ended; result=-1
Type 'less /var/log/mondoarchive.log' to see the output log


Voici le log (/var/log/mondoarchive.log) :


[TH=3961] libmondo-tools.c->reset_bkpinfo#856: Hi
root is mounted at /dev/sda

No, Schlomo, that doesn't mean /dev/sda is the root partition. It's just a debugging message. Relax. It's part of am_I_in_disaster_recovery_mode().
[TH=3961] libmondo-devices.c->am_I_in_disaster_recovery_mode#147: Is this a ramdisk? result = 0

Quelqu'un aurait-il la solution?
