Applicable Scenarios

You can employ lifecycle management to automatically delete files that are no longer accessed or transition files that are infrequently accessed to Infrequent Access (IA) or Archive storage. This approach reduces costs and optimizes storage resource utilization.

• Periodical data deletion: When the versioning feature is enabled for a bucket, a large amount of historical version data is accumulated in the bucket due to data overwriting and deletion. Expired or unnecessary data needs to be automatically deleted at regular intervals.

• Storage type transition: Data needs to be automatically moved to IA or Archive storage when its access frequency decreases.

• Regulatory compliance requirements: Lifecycle management meets regulatory compliance needs, ensuring adherence to data retention periods and deletion requirements while safeguarding data security and releasing storage resources.

Advantages:

• Reduced storage costs: Lifecycle management automatically moves data to more cost-effective storage types or deletes data based on access frequency and importance. Data that is infrequently accessed and requires long-term retention is moved to Archive storage, reducing storage costs.

• Simplified data management: Lifecycle management eliminates the need for manual intervention during data storage. Once appropriate policies are set, the system automatically executes transition and deletion operations. This saves time and effort for management personnel while also reducing the risk of manual errors.

• Ensured compliance: Lifecycle management guarantees that data is managed in accordance with laws and industry regulations. You can set policies to define data retention periods and automatically delete data, ensuring compliance with privacy and security regulations.

Before You Begin

• Service data, such as video surveillance footage, has explicit retention requirements.

• The versioning feature is enabled for the bucket and excessive historical version data can be deleted.
