How to Delete Files Older Than 30 Days in Azure Storage | Azure Data Engineer Mock Interview

Want to crack Azure Data Engineering interviews with confidence? This playlist is your complete roadmap.

In this video, I explain a very practical interview question:
👉 How to delete files automatically older than 30 days in Azure Storage?

In Azure Blob Storage, we use Lifecycle Management Policies to automatically delete or manage old files.

✔ Define rules to delete blobs based on age
✔ Automatically runs without manual intervention
✔ Helps reduce storage cost
✔ Best practice for data retention

👉 Real-time scenario:
In data engineering projects, we configure lifecycle policies to delete staging or temporary files after 30 days to optimize storage and maintain clean data layers.

This is not just theory. Every answer is explained the way experienced professionals speak in real interviews.

🔥 What you will learn:

Azure Storage Account (Blob vs Data Lake Gen2)
Blob Types & Access Tiers (Hot, Cool, Cold, Archive)
Azure Data Factory (ADF) real-time pipelines
