Preventing file access in Azure storage account using archive tier

You can prevent access to a specific file in your Azure storage account by changing its tier to the archive tier. This method ensures that the file cannot be read or modified without affecting access to other files and containers. Follow these steps to change the tier to archive for a single file:

1. Go to the Azure portal and open the storage account containing the file.
2. Find the specific blob you want to restrict.
3. Set the access tier of the blob to "Archive."

Note that data in the archive tier should be stored for at least 180 days. If you move a blob to the archive tier and then delete it or move it to the hot tier within 45 days, an early deletion fee equivalent to 135 days (180 minus 45) will be charged.

For bulk archiving at the container level, use the Azure Lifecycle Management feature, which lets you define policies for efficient data management across containers.
