Restoring Objects from the Archive or Deep Archive Storage

Scenarios

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

Objects can be restored at an expedited or a standard speed. With the expedited speed, it takes 1 to 5 minutes to restore Archive objects and 3 to 5 hours to restore Deep Archive objects. With the standard speed, it takes 3 to 5 hours and 5 to 12 hours to restore Archive and Deep Archive objects, respectively.

To restore a large number of objects from the Deep Archive storage class, you are advised to use the standard restore. The restore time spent depends on the object size restored.

Constraints

• If an Archive or Deep Archive object is being restored, you cannot suspend or delete the restore task.
• You cannot re-restore an object that is in the Restoring state.
• 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.

  During the restore validity period, you will be billed for the space taken up by both the object and its copy. The copy will be automatically deleted upon expiration of its validity period.

How to Use

You can use OBS Console, APIs, SDKs, OBS Browser+, or obsutil to restore Archive objects.
