For more information, see Lifecycle Management.

  4. Configure related parameters.

    • Status: Select Enable to enable this lifecycle rule after the configuration.
    • Rule Name: Enter a rule name that is no longer than 255 characters.
    • Applies To: By selecting Object name prefix, the lifecycle rule will apply to objects with the specified prefix contained in their name. You can also select Bucket for the lifecycle rule to apply to all objects in the bucket.
    • If Object name prefix is selected and the specified prefix and the prefix in an existing lifecycle rule overlap, OBS regards the two rules as one and forbids you to configure the current rule. For example, if there is a rule with prefix abc in the system, another rule whose prefix contains abc cannot be configured.
    • If there is already a lifecycle rule whose Applies To is set to Object name prefix, you are not allowed to configure a new rule whose Applies To is set to Bucket.
    • If there is already a lifecycle rule whose Applies To is set to Bucket, you are not allowed to configure a new rule whose Applies To is set to Object name prefix.
    • You can use a lifecycle rule to specify the number of days after which objects that have been last updated and meet specified conditions are automatically transitioned to the Infrequent Access or Archive storage class, or are automatically deleted upon expiration.
      • Transition to Infrequent Access: This rule transitions the objects meeting the conditions to the Infrequent Access storage class after the specified number of days since the last object update.
      • Transition to Archive: This rule transitions the objects meeting the conditions to the Archive storage class after the specified number of days since the last object update.
      • Expiration Time: This determines when an object will expire and then be deleted, or the day after which objects matching the rule will be deleted.

  5. Click OK to save the lifecycle rule.
