> so not inside /opt/firebird

Sorry, I think I misunderstood the question, the firebird files are all located in /opt/firebird/
I'm pretty sure I installed it using the Ubuntu package manager, but I installed it on this machine months ago so I don't remember for sure. The nbackup program is located in /opt/firebird/bin/ and has -rwxr-xr-x rights.
Sorry for the confusion and thanks for all your help thus far.
