This environment variable specifies the Azure storage account name 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.

Because Azure storage accounts have unique endpoint URLs (for example, primaryacct.blob.core.windows.net), this variable points directly to the primary storage account rather than using a bucket name replacement. This is why AZURE_RECOVER_FROM_REPLACE_BUCKET is not used for Azure DR.

During reverse recovery (failback), this variable points to the secondary storage account name.
