Authorization Issue Azure Blob Storage

Question

I have an Azure Database Migration Project migrating an on-premises db to Azure SQL Managed Instance. The activity works fine pulling the database backup from the network location on-premises, but when it tries to apply the backup file from Azure Blob storage it says it does not have access to the file.

The Azure storage account has a storage endpoint, but I noticed that the storage account is not in the same resource group as my Managed Instance. Does that matter at all? Also is there a way to look at the logs for that authorization failure in the Azure Portal or Azure Storage Explorer?

Answer 1

Please check if you have set the role permission to access the Azure Storage:

Add role assignment:

1. Role: choose the role (such as 'Contributor')
2. Assign access to: Azure AD users, group, or service princpal
3. Select: choose your Azure AD users, group, or service princpal.
