Folks,

Put a "Label Media = yes" line in your device config of your bacula-sd.conf 
file.  Do NOT set a LabeLFormat value for tapes if you're using barcodes. 
The only thing you need to do then is add each volume to the database 
individually, then if the tape is truly blank bacula will label it properly 
based on the barcode.  If it was written with some other backup system you 
may have to label it manually or write EOF's to it first.  Bacula's 
auto-label stuff works well but last I checked wasn't well documented.

To add volumes to the database you can use the menus but that's a pain if 
you do more than one or two.  I've got a script to add multiple volumes to 
the database.  I believe I got at least part of it from here so I claim no 
ownership.

Enjoy,
