Hi,

     I have a mail server running Debian 4.0 and bacula version  
2.2.8-8~bpo40+1 installed from debian backports. The mail server runs 
postfix + courier-imap and size of full backup it´s 108 Gb aprox.
    I´ve got a lot of machines on the network who are been backed up 
succesfully, but the mail server sometimes when run a incremental 
backup, it´s seems to be an incremental but bacula copy all data like in 
a full.

Log of backup:
