Business Central 24x7

Hi there,
 
We are implementing the Business Central on Dynamics 365 cloud. I want to ask you the following important questions related to the fail-over for the Dynamics 365 Business Central applications.
 
1. Because we are using the cloud version of Dynamics 365, could you explain how Microsoft ensures system uptime and reliability? 
 
2. In the event that Business Central becomes inaccessible or experiences downtime, such like the recent AWS outage that affected multiple applications, who should we contact for support? Does Business Central have SLA (service level agreement)?
 
3. Because we are using the cloud version of Dynamics 365, and we don't have the access to the database. Who is responsible for backing up the database and where it is securely stored? Additionally, if we encounter a situation where the database is unavailable or data is lost, what should we do?
 
Thanks
 
Jamie

    Hello,
     
    Business Central Online runs on Microsoft Azure with built-in redundancy and a 99.9% uptime SLA.
    Microsoft manages all backups, automatic daily backups kept for 28 days, restorable from the Admin Center.
    If downtime occurs, check the Service Health Dashboard or contact Microsoft Support via your 365 Admin Portal.
     
    Regards,
    Oussama Sabbouh
