Question

A media company stores raw video footage uploaded by field crews in Azure Blob Storage. Files are large (multi-GB), accessed frequently for the first 30 days during editing, occasionally for the next 90 days, and then rarely accessed but must be retained for 7 years for legal compliance. The company wants to minimize storage costs while ensuring files remain retrievable within milliseconds during the editing window. Which approach should you recommend?

Accepted Answer

Configure a lifecycle management policy that keeps blobs in Hot for 30 days, moves them to Cool after 30 days, and to Archive after 120 days.

Answer

Store all files in the Archive tier and rehydrate them on demand when editors need access.

Answer

Keep all files in the Hot tier for the full 7-year retention period to guarantee fast access.

Answer

Store files in Premium block blob storage and delete them after 120 days to control costs.
