A Blueprint report will tell you exactly how your platform was configured on any specific backup point and can be accessed from the job history section of the screen.

Why is this useful?

This enables you to take a definitive snapshot of how your tenancy was configured on a certain date and is essential for compliance and auditing, including (ISO27001:2022 8.9 Configuration Control and NIST SP 800-128). The report can also form part of a security review process.

Blueprint reports are HTML documents, which show every configuration element and since this is a full-fidelity configuration backup, the report is comprehensive.

Descriptions as to what each item means can be found on the Microsoft365DCS documentation, for example, the above object is for AADApplication.
