Glory
Typically, glory in archiving comes from the knowledge that what you're doing will be preserved for years, decades, perhaps even centuries to come. You know how important record keeping is to civilization―just look at the difference between the incredible discoveries and innovations of Rome and the Game of Thrones-level horror that was the Dark Ages.
There's a certain satisfactory spark that comes with knowing that future generations will benefit from your work in some way, even if it's just being able to find a really great recipe for kale frittatas.
There's also the glory that can be given by your position. Running a film vault is cool, sure, but what about running the Disney vault? Working at a college is neat, but what about being the lead archivist at Harvard? There's even a position called the Archivist of the United States, appointed by the gosh-darned President of the United States. Work your little butt off, make the right connections, and the glory will follow.
