In cloud storage, retention policies are often used to manage the lifecycle of data, determining how long data should be retained and when it should be deleted. A rolling retention storage method could imply a dynamic approach where data is continuously retained for a specific period, and as new data is added, older data is automatically removed based on the defined retention period.

This approach ensures that storage resources are efficiently utilized by automatically removing outdated or less relevant data to make room for new data. It can be particularly useful in scenarios where the storage capacity is limited or there are cost considerations associated with storing large volumes of data over extended periods.
