Setting the Direct Reading Policy for Archive Objects in a Bucket

Functions

The direct reading function of Archive objects means that a user can directly perform operations on the Archive objects without restoring them.

By default, the direct reading function is disabled in a bucket.

This API enables or disables the direct reading function for Archive objects of a bucket.

  • When the function is Enabled:
    • You can directly perform operations on the Archive objects of a bucket regardless of whether they have been restored.
    • If the Archive objects are not restored, your operations on them will be charged separately.
  • When the function is Disabled:
    • You need to restore the Archive objects before you perform any operation on them.

To perform this operation, you must have the PutDirectColdAccessConfiguration permission. By default, only the bucket owner can perform this operation. The bucket owner can grant the permission to other users by configuring the bucket policy or user policy.

The direct reading function is available only in the following regions: CN North-Beijing1, CN North-Beijing4, CN East-Shanghai2, CN South-Guangzhou, CN Southwest-Guiyang1.
