Many records are not kept digitally but only in hard copy. This is especially true of legacy data, but it also holds true for particularly sensitive data. That "plane that flew into the Pentagon" in 2001 gives testament to this.
Records for all transactions are required by corporate law everywhere in the world (articles of incorporation). Keeping those records in paper form satisfies the contract. Accidental fires that seem to be preferentially localized to the records rooms are an unfortunate hazard for paper records, but it's a risk that the PTB are willing to take for "security."
