The complete FileSet is:
# List of files to be backed up
FileSet {
Name = "FullSet"
Include {
Options {
signature = SHA1;
verify=pins1;
accurate=pins1;
}
File = /boot
File = /
File = /home/stud
File = /home/wimi
File = /opt
File = /fs/images
File = /fs/vmware
File = /fs/backups
}
Exclude {
File = /var/lib/bacula
File = /tmp
File = /proc
File = /tmp
File = /.journal
File = /.fsck
}
}

Done. The error occurs only during the differential run, on the same file as
before
/usr/share/postgresql-8.4/man/man7/table.7.bz2
That file is backed-up, though: (together with a dummy one I created to force
the differential):
*list files jobid=17
+--------------------------------------------------+
| filename |
+--------------------------------------------------+
| /usr/share/postgresql-8.4/man/man7/ |
| /usr/share/postgresql-8.4/man/man7/table.7.bz2 |
| /usr/share/postgresql-8.4/man/man7/I_AM_FAKE_AHK |
+--------------------------------------------------+
I assume that Bacula is being conservative here: Unless it can prove (by
identical checksums) that a file has not changed, it will back-up the file?

gundabad-fd: accurate.c:224-19 add
fname=</usr/share/postgresql-8.4/man/man7/table.7.bz2> lstat=PwA Dky9 IGk C A
A A 6 BAA I BMBmj+ BMBmj+ BMBmkF BU A C chksum=
Note that `chksum=´ is empty.
> What is the add fname message for a file that doesn't give the warning?
gundabad-fd: accurate.c:224-19 add
fname=</usr/share/postgresql-8.4/man/man7/alter_tablespace.7.bz2> lstat=PwA
Dkxm IGk B A A A Kz BAA I BMBmj8 BMBmj8 BMBmkF A A C
chksum=vJvtTQ9F2sguOypX9ThR7u5IJi8
Here, chksum has a value.
Also I did some more experimentation: The problem only occurs when I set
Accurate = yes (as I have normally done). If I change that to no, no warnings
are shown.
Please let me know if you need more info!
Assuming it is a bug, where can I file a bug report?
Best,
Andreas
