Ok people like me and some colleague where not up to date on the whole
debconf/dbconfig universe and get mislead be the man page.

You're absolutely right, with the help of our deb guru, we have been able to
figure out how to do this, by simply explaining (in our documentation) how to
disable it.
```
echo "bareos-database-common bareos-database-common/upgrade-backup boolean
false" | debconf-set-selections -v
```
Will simply do the trick.

;-) was a suggestion, and if you find the idea to be useful I will simply open
a new one, but if it has now chance to be fixed, then it can stay like it is.

Thanks for your proposal, adding the "debconf" would at least for myself ring
a bell that's not concerning the module but the global state.
I'm not too confident in myself and my limited knowledge of the debconf system
doesn't allow me to propose something that would make the sentence more easier
to understand even with a quick look.
But still the non empty is a bit wired compared how to all the other variables
are used ('true', 'false') might be a "ancient time" way of life ;-)
