Better documentation in this area, I see bits and pieces that point to the possibility in a worst case scenario all I would need is an offsite copy a volume and the relevant bootstrap file to extract the data in the volume. I have not found a way to do that in the documentation, what I do see is restoring the catalog from the bootsrap along with the server config files. That seems a bit complex that the data can't be extracted without a running bacula catalog database and server.
