We use a Microsoft authorized API called Graph to interface with your M365 tenant. Our M365 backup support is provided through our BluVault BaaS (Backup as a Service) offering and it is a cloud-cloud backup. It doesn’t require any infrastructure on your premises and it doesn’t impact your office network or your user’s network bandwidth in any way. In order to enable us to use the Graph API, as a one-time step, we will require you to authorize Parablu’s Azure Active Directory App to run against your MS 365 tenant. Once that is done – backups run automatically based on the schedules you specify. Completely set and forget.
