If you're on enterprise, you can use the Legal Discovery feature (vault) instead - it worked at my previous employer when all the HR files mysteriously vanished. I think they maintain it properly because otherwise they might get summoned in a case. The downside is that it does a format conversion to word format (and presumably Excel for sheets), and doesn't export in the same directory structure (although I bet the metadata exists in the dump somewhere)

Oooh, this sounds promising - thank you so much!
