Kern, Doors are special files that are used for inter-process calls. Basically the calling process goes through a door into another (server processes) context, does the processing and returns. It is designed as a quick interprocess mechanism that doesn't involve a full context switch to a different stack context. They work in a similar way to fifo where a process associates itself with a filesystem node and registers a number of handler threads that do work on their behalf.
I guess that the fact that you haven't heard of doors means that bacula hasn't either. I don't remember exactly how you make a door filesystem entry and I don't have a Solaris system on hand to take a look further. The man page for door_create(3DOOR) lives at http://docs.sun.com/app/docs/doc/816-5171/6mbb6dcne?a=view I don't remember whether these need "restoring" although I suspect that they do because some of their functionality may be needed early on in boot.
