Hi @Sonu jatav
Welcome to Microsoft Q&A thanks for posting your question.
As I understand it, you're unable to find the backup files in the storage account.
If you're looking to persist data, you can consider using the managed Azure Cache for Redis service.
Choose a storage account in the same region and subscription as the cache. A Premium Storage account is recommended due to its higher throughput. Additionally, we strongly recommend disabling the soft delete feature on the storage account, as it can increase storage costs. For more information, please refer to the relevant documentation.

Note that data persistence is not available in the Basic and Standard tiers.
Please let me know if you need any more information. We are happy to assist
