Modern cyber insurance applications (from carriers including Chubb, AXA, Travelers, Beazley, and Coalition) now explicitly ask whether you maintain backups that are independent, immutable, and regularly tested.
If you suffer a data protection event and your only "backup" was Intuit's platform-level business continuity — which you don't control and cannot restore from — insurers can deny your claim on grounds of failure to implement adequate data protection controls.
The 3-2-1 Backup Rule is now a de facto standard in cyber insurance underwriting: 3 copies, 2 different media, 1 offsite. QuickBooks alone satisfies none of these for your individual data.
