Follow-up Procedure

You can specify its storage class when uploading an object or change its storage class after the upload in the object list. The procedure is as follows:

NOTE:
  • Objects can be changed from the Standard storage class to Warm or Cold storage class. Objects can be changed from the Warm storage class to Standard or Cold storage class. Objects of the Cold storage class must be restored before being changed to Standard or Warm storage class. The latter two changes incur penalty and restoration fees. Determine an appropriate change path based on your actual needs.
  • You can also transition storage classes by configuring the lifecycle rule. For details, see Lifecycle Management. For details about differences between changing storage classes in the object list and transitioning storage classes through the lifecycle rule, see Object Storage Classes Overview.
