No. The history posted by "Le Dahut" does not end on 9/17. Beginning 
from 17/09, all files are backed up every day with incremental backup 
whatever the mod date is (I have some files that has not been modified 
since 2k8 and bacula backup these files every day).

My problem is :

- Everything worked fine until 9/16
- Bacula saves every files on incrmental since 9/17  (see list jobs in 
my previous mail)
- Files have not been modified between backups
- bacula calculate identical hashes on each backup
- Incremental backup are real incremental, bacula doesn't upgrade to a 
full (more precisely, bacula doesn't report an upgrade).


I don't know how I can see what makes bacula think files have been 
modified. Maybe it is possible to log more to see what triggers backup 
of my files ?
