Hi @Devanshi Patel ,
Thank you for your reaching out and welcome to Microsoft Q&A!
Are you worried about whether the data in the database will be lost if all the servers are unavailable? Please refer to this official documentation, we can get the information:
In addition, we can always add a database of the same Azure SQL Server to an existing failover group. When a new database is added to the existing failover group, it automatically creates a new database in the secondary server with the same name, edition and computes. For more information, please refer to Failover groups overview & best practices.
Best regards,
Lucy Chen
