The [msdb database](/sql/relational-databases/databases/msdb-database) enables backup transparency in Azure SQL Managed Instance by making backup history tables queryable. However, there are a few key differences between the backup tables in a traditional SQL Server `msdb` database, and the `msdb` database in Azure SQL Managed Instance, such as what information is visible, what tables are supported, and what fields are available.

Backup transparency in SQL Managed Instance is available through the [msdb database](/sql/relational-databases/databases/msdb-database), which makes backup history tables queryable.

It's important to know about a few key differences between the backup tables in a traditional SQL Server `msdb` database and the `msdb` database in SQL Managed Instance. The main differences include the information that's visible, supported tables, and the fields you can use.
2423

25-
- The type of automated backup taken, such as full, differential, or log.
26-
- Metadata about native backups taken manually, though some fields, such as file path and usernames, may not be populated. Use the `is_copyonly` column to determine if a backup was taken manually or automatically.
27-
- Metadata about the backup such as the status, size, time, and location.
28-
- The replica where the backup was taken, such as the primary, or secondary. The ability to take backups from the secondary replica is currently in private preview, and only available on the Business Critical service tier.

When reviewing your backup history in the `msdb` database, consider the following:
60-
61-
- Backup history doesn't contain all information about user-initiated backups, such as usernames of the user who initiated the backup.
62-
- Fields that aren't relevant to the cloud won't be populated, such as the machine name, physical drive, and physical name.
63-
- Backup information is inserted to the `msdb` database when the backup completes. Ongoing backups aren't supported.
