Exam DP-300 topic 6 question 51 discussion

Answer correct - SAS and COPY-ONLY. In Azure SQL Managed Instances, the COPY_ONLY option is required because the service manages the regular backup chain. The COPY_ONLY backup ensures that the backup chain is not interrupted or affected, which is essential for Azure SQL Managed Instance. So, the correct completion of the command should prioritize COPY_ONLY to meet the requirements of the managed instance environment.

The answer is correct https://techcommunity.microsoft.com/t5/azure-sql-blog/native-database-backup-in-azure-sql-managed-instance/ba-p/386154 The only mandatory property is COPY_ONLY. Azure SQL Managed Instance owns the backup chain. This means that you cannot perform database backup that breaks the backup chain. Azure SQL Managed Instance allows you to perform only COPY_ONLY backups.

Going with COMPRESSION because according to best practices it can save on costs: https://learn.microsoft.com/en-us/sql/relational-databases/backup-restore/sql-server-backup-to-url-best-practices-and-troubleshooting?view=sql-server-ver16#manage-backups
