Hello Rui Domingos (JTA Consulting S A),
Thanks for posting your question in the Microsoft Q&A forum.
Azure Analysis Services currently does not natively support using User Managed Identities for backups to Azure Blob Storage. However, there are a couple of alternative approaches you can consider:
- Create a local backup of your Azure Analysis Services database, use Azure CLI or Azure PowerShell with a User Managed Identity to upload the backup file to Azure Blob Storage.
- Create an Azure Automation account with a User Managed Identity, develop a runbook that performs the backup and uploads it to Azure Blob Storage and schedule the runbook to run at desired intervals.
