Description

The blob soft delete configuration ensures that storage blobs remain recoverable for a set time even if data is deleted. Enabling soft delete protects data from user error or malicious actors that may deliberately delete data.

How to fix?

Set Microsoft.Storage/storageAccounts/blobServices properties.deleteRetentionPolicy.enabled attribute to be true and properties.deleteRetentionPolicy.days to 7 or greater.

Example Configuration

{
    "type": "Microsoft.Storage/storageAccounts/blobServices",
    "apiVersion": "2021-06-01",
    "name": "azure-648-allowed/default",
    "properties": {
        "deleteRetentionPolicy": {
        "days": 7,
        "enabled": true
        },
        "isVersioningEnabled": true
    }
}
