Restoring Archive or Deep Archive Objects

Scenarios

You must restore an object in the Archive or Deep Archive storage class before you can download it or access it with a URL.

To learn the costs involved in data restore, see Product Pricing Details.

Important Notes

  • After an object is restored, an object copy in the Standard storage class will be generated. This way, there is an Archive or a Deep Archive object and a Standard object copy in the bucket at the same time. After an Archive or Deep Archive object is restored, the object status displays Restored, and the generated object copy in Standard storage class is not displayed in the bucket.
  • After versioning is enabled, if you do not specify a version ID, OBS restores the current version. You can specify a version ID to restore a specific version.
  • If the RestoreObject API is called for the first time, 202 will be returned, indicating that the server has received the request. If the RestoreObject API is called again after a successful object restore, 200 OK will be returned.

Constraints

  • Archive and Deep Archive objects can remain in a restored state for a maximum of 30 days.
  • If an Archive or a Deep Archive object is being restored, its restore speed cannot be changed, and the restore task cannot be suspended or deleted.
  • If you attempt to restore an object that is being restored, error 409 will be reported. Wait for the current restore to finish before trying again.
  • Objects that are being restored cannot be added to a batch restore.
