This environment variable specifies the Azure Blob storage endpoint URL for the primary storage account to recover data from. It is deployed only on the secondary (standby) cluster when dr="standby" and is removed when promoting to dr="active". Removing this variable changes the HumioCluster spec and may cause the operator to restart pods during promotion.

Azure storage accounts each have a unique endpoint URL (for example, primaryacct.blob.core.windows.net). This variable points directly to the primary account endpoint. This is why AZURE_RECOVER_FROM_REPLACE_BUCKET is not used for Azure DR — swapping container names while keeping the secondary endpoint would cause 403 authentication errors. Use BUCKET_STORAGE_MULTIPLE_ENDPOINTS to ensure each bucket retains its own endpoint configuration.

During reverse recovery (failback), this variable holds the secondary storage blob endpoint.
