Yeah, I tried that, too.  It's only listing files that got changed/are
new and should be backed up.  Although, total is still very high.

+-------+--------+---------------------+------+-------+----------+----------------+-----------+
| jobid | name   | starttime           | type | level | jobfiles |
jobbytes       | jobstatus |
+-------+--------+---------------------+------+-------+----------+----------------+-----------+
| 1,105 | tic FS | 2011-01-10 02:05:08 | B    | I     |    4,585 |
39,502,153,253 | T         |
+-------+--------+---------------------+------+-------+----------+----------------+-----------+

Again, even though it's showing the jobbytes = over 39GB on disk it's
taking max 6GB.  I can see how much space individual volumes are
taking.

The fileset I am using is as follows (although I can't really see how
that could affect things...):

FileSet {
    Name                    = "tic FileSet"
    Include {
        Options {
            accurate        = mcs1
            basejob         = pmugcs1
            checkfilechanges= yes
            compression     = GZIP
            fstype          = ext2
            noatime         = yes
            onefs           = no
            signature       = SHA1
            verify          = pins1

            wilddir         = /dev
            wilddir         = /proc
            wilddir         = /tmp
            wilddir         = /var/tmp

            Exclude         = yes
        }
        File                = /
    }
}

Also, it's Bacula 5.0.3-2 re-compiled from sources provided on www.bacula.org.

If anyone has any idea on what would be causing that mis-behaviour I
would greatly appreciate advise.

Kind regards.
