Answer options:
Create an Azure Automation runbook that runs a PowerShell script daily to change the access tier of older blobs.
Configure a Lifecycle Management policy to move blobs to the Cool tier after 30 days, and to the Archive tier after 180 days.
Use Azure Data Factory to copy data older than 30 days to a new Storage account configured with the Cool tier.
Enable Blob versioning and set the default access tier of the storage account to Archive.
