6. The Create New Instance page is displayed for you to create an instance using the backup data. The new DB instance is independent from the original one.
   • You are recommended to deploy the restored DB instance in a different AZ to ensure that applications will not be adversely affected by the failure in any single AZ.
   • The database type, DB instance type, compatible MongoDB version, storage engine, and storage type must be the same as those of the original and cannot be changed.
   • The storage space is the same as that of the original instance by default. You can increase the storage space, but you cannot reduce it.
   • Other settings have default values and can be modified. For details, see Buying a Replica Set Instance.
   • A full backup is triggered after the new instance is created.
