What Are the Application Scenarios of Lifecycle Management?

You may configure lifecycle rules to:

Periodically delete logs that are only meant to be retained for a specific period of time (a week or a month).
Transition documents that are seldom accessed to the Warm or Cold storage class or delete them.

If you want to delete a large number of objects from a bucket, you can configure a lifecycle rule to automatically delete the expired objects. Table 1 lists the parameters for configuring such a lifecycle rule on OBS Console.

**Table 1** Parameters for deletion upon expiration

Status	Enable
Rule Name	Example: rule-delete
Applies To	You can apply the deletion rule to the entire bucket or to objects that share the same name prefix in the bucket.

One day later, objects in the bucket are successfully deleted based on the rule. If you do not need this lifecycle rule, you can disable it or delete it.
