Hi all,

I run server 9.6.7 on Debian 11 which appears to be working fine with a range of clients: 5.2.6, 9.4.2 and 9.6.7.

I'm wondering what typically happens when i.e. user decides to distro upgrade Ubuntu 20 to 22 and, as a result, the client upgrades to a version > 9.6.7?

Will it likely continue working without issues as long as the version gap is not too big?

Will I get a stern warning on the server if there is a problem?

Or could it fail silently only for a serious issue to be discovered on restore?

It is simple, DIR == SD >= FD.

That was pretty much set in stone when Bacula started out, Kern understood that backup and restore has to keep working, changes that interfere with that were not acceptable.

I have systems running 3.0.3 still happily talking to a 9.6.7 director.

And the people now managing Bacula development appear to be immune to the, "Oooh, shiny, we don't care if it breaks existing behaviour", effect that plagues FLOSS projects.

So yes, if you are using distribution-based Bacula for your clients you will get a failure when one breaks the rules.

This is why you should build from source.

        Cheers,
                Gary    B-)
