I have been working on a configuration for backing up to disk during  
the evening and then copying the volume(s) to tape using a copy job  
during the day.  I have previously only used Bacula to back up to disk  
volumes and need some pointers on how to solve a couple of issues that  
I am running out of time to resolve.

My first issue is that a copy job will only copy a volume if it has a  
status of full, used or error.  For the most part I have always used  
"Volume Use Duration" when using disk volumes.  This leaves the volume  
in append mode until the next usage, so "last nights" volumes are not  
selectable for copying "today".  At the moment I have used "Max Volume  
Jobs = 1" which gives me multiple volumes in a "used" state to copy.   
This works and I do not have an issue with it, but I was wondering if  
there is away of "forcing" the Volume Use Duration" to take effect  
prior to the next use of the volume?

My second issue is with the loading and unloading of tapes.  I want to  
users to load and unload tapes as prompted by emails.  The users will  
have no bconsole access.  The system is Centos 5.5 with an HP Ultrium  
920 LTO3 tape drive.  I have tried a few things but cannot find an SD  
configuration that does not require the manual mounting/unmounting of  
tapes most of the time.  Am I correct in assuming that the only way to  
do this reliably to is to use a "virtual auto-changer" script"?  If so  
does the ak-mtx-changer.txt script that is on the distribution  
examples directory work with Bacula 5.0.3?  I found some information  
that suggested that it does not and just what to understand what I am  
getting into before I go there :-)

Thanks

Mike
