Hi Allen,
No, there is no automatic backup of Azure storage accounts. There are redundancy options to help make it more tolerant to hardware failures, natural disasters, etc., but that is different than backup.
For backing up blob storage you can use Azure Backup. Below article walks through setting it up:

You can back up Azure Files to Recovery Services Vault. Article below has details:

Currently there is no built-in method for backing up table and queue storage, so if you need that you would need to use script or other solution.
For more information about related options such as soft delete, versioning, immutability, please see below article:
