Object Storage Service:Fees related to lifecycle rules

API operation calling fees

Successful API operations that are asynchronously called to perform actions triggered by lifecycle rules are recorded in access logs. You are charged for only successful API operations. Failed operations are not recorded or charged. The following section describes the fees generated when API operations are called to convert the storage class of objects or delete objects based on lifecycle rules:

• Fees generated when API operations are called to convert the storage class of objects

  You are charged based on the storage class of objects before storage class conversion. For example, when you convert a Standard object to an Infrequent Access (IA) object, you are charged for API operation calls based on the Standard storage class. When you convert an IA object to an Archive object, you are charged for API operation calls based on the IA storage class.

  Important

  When you convert an IA object to an Archive, Cold Archive, or Deep Cold Archive object based on lifecycle rules, you are charged higher fees compared with converting a Standard object to an IA, Archive, Cold Archive, or Deep Cold Archive object.

• Fees generated when API operations are called to delete objects

  When you delete an object, you are charged based on the storage class of the object.

  Important

  When you delete an IA, Archive, Cold Archive, or Deep Cold Archive object based on lifecycle rules, you are charged higher fees compared with deleting a Standard object.

For more information about API operation calling fees, see API operation calling fees.

Storage fees

You are charged for the objects stored in Object Storage Service (OSS) based on the storage class, size, and storage duration.

IA, Archive, Cold Archive, and Deep Cold Archive objects have a minimum billable size. Objects that are smaller than 64 KB are charged as 64 KB. Objects that are greater than or equal to 64 KB are charged based on their actual sizes.

If you delete an IA, Archive, Cold Archive, or Deep Cold Archive object within the minimum storage duration based on lifecycle rules, you are charged for the storage usage of the object that is stored for less than the minimum storage duration.

• Fees generated by objects that are converted from Standard to IA or Archive and then deleted within the minimum storage duration based on lifecycle rules

  The minimum storage duration is 30 days for IA objects and 60 days for Archive objects. The minimum storage duration of an IA or Archive object is calculated from the time when the object is last modified.

  For example, if you convert the storage class of a Standard object to IA 10 days after the Standard object is created, convert the storage class of the IA object to Archive after 20 days, and then delete the Archive object after 5 days based on a lifecycle rule, you are charged for the storage usage of the Archive object that is stored for less than the minimum storage duration (25 days).

• Fees generated by objects that are converted from Standard, IA, or Archive to Cold Archive or Deep Cold Archive and then deleted within the minimum storage duration based on lifecycle rules

  The minimum storage duration is 180 days for Cold Archive and Deep Cold Archive objects. The minimum storage duration of a Cold Archive or Deep Cold Archive object is calculated when the object is converted to a Cold Archive or Deep Cold Archive object.

  For example, if you convert the storage class of a Standard object to Cold Archive or Deep Cold Archive 10 days after the Standard object is created, and then delete the Cold Archive or Deep Cold Archive object after 1 day based on a lifecycle rule, you are charged for the storage usage of the Cold Archive or Deep Cold Archive object that is stored for less than the minimum storage duration (179 days).

• Fees generated by objects that are converted from Cold Archive to Deep Cold Archive and then deleted within the minimum storage duration based on lifecycle rules

  The minimum storage duration is 180 days for Cold Archive and Deep Cold Archive objects.

  For example, if you convert the storage class of a Cold Archive object to Deep Cold Archive after 10 days, and then delete the Deep Cold Archive object after 1 day based on a lifecycle rule, you are charged for the storage usage of the Cold Archive object that is stored for less than the minimum storage duration (170 days) and the storage usage of the Deep Cold Archive object that is stored for less than the minimum storage duration (179 days).
