I assume the Catalog is the database structure used by Bacula Director to perform its operations. In this case the only catalog manipulation (update) the IBAdmin is doing is job and volume comment field update. All other write operations are performed using IBAdmin specific objects structure which is not a part of the Catalog. > > All management is based on database objects.

IBAdmin does not store its configuration data in Bacula Catalog but stores it in the same Postgresql database. > If so, why?

You will have to connect to it anyway. :) Do you think an average Bacula user or even a newbie who have a serious problems to setup a basic Bacula installation (just check bacula-users mailing list) will be happy when he has to setup an another database just to use a simple IBAdmin when all other Bacula GUIs do not require it? I think it is impossible to make everybody happy. :) > > I assume you want to test it, right? > > > Yes, I do, I am interested, but not if I must give it write access to my > Bacula database. > Do you use any Bacula GUI except BAT? Do you know that all of them require the same database write access as IBAdmin does. >From technical point of view it is possible to redesign IBAdmin to use multiple databases, but it requires some development which (in my opinion) has no real value. If you think this kind of separation has any real value other then "do separation - it is good" I'll be happy if you will share it with me. best regards -- Radosław Korzeniewski rados...@korzeniewski.net
