That seems a working solution, but creating a symbolic link for every
volume required by a restore job introduces a manual operation that would
be better to avoid, especially if a lot of incremental volumes are being
considered.

I suppose that using "vchanger", suggested by John in this thread, or the
"disk-changer" script, provided by Bacula, is the only solution to automate
the symbolic links creation.

But, in my opinion, an Autochanger is a too specific tape related concept
that introduces a lot of complexity that is not really needed by a
filesystem solution, i'd prefer not to deal with redundant configuration
tasks performed exclusively in order to work around software architectural
lacks... but of course i will if i'm obliged to: in my environment it is
important to have different directories for each job level.

Do you, Uwe, confirm that an Autochanger is the only way to have working
and automated restore jobs with volumes in different directories?

Thank you again.
