Manged instance and IAAS .bak file is working. AZURESQLDB is not supporting.bak file.Why..??

[@rajasekhar_reddy_bolla]

@@RekhaM-zk6bh Azure SQL Database is a fully managed platform-as-a-service (PaaS) offering, meaning Microsoft manages the underlying infrastructure, including backups, high availability, and scalability. Because of this, direct access to the file system (like .bak file restoration) is not available. Instead of restoring .bak files, you need to export data using tools like BACPAC or DACPAC to move databases in and out.
