Overview

Archived objects can be restored in the COS Console, so that they can be accessed or manipulated. For more information about object storage classes, see Object Overview.

The restoration operation will create a replica of the object in standard storage class, which can be read and downloaded. The object replica will be billed as a standard storage object. If the source object is not deleted, it will continue to be billed as an archive storage object. For pricing details, see Product Pricing.

Directions

  1. Log in to the COS Console and click Bucket List in the left sidebar to enter the bucket list page.

  2. Click the bucket name to enter the bucket details page.

  3. In the "File List" module on the bucket details page, click Restore in the "Action" column to the right of the object you want to restore.

  4. In the dialog box for restoring the archived object, configure the restoration mode and the validity period in days of the replica. The related configuration items are detailed below.
    Restoration Mode: Standard, Expedited, or Batch mode.

    • Expedited mode: This is the fastest way of restoration. Files below 256 MB can be restored in 1 to 5 minutes. When you need to access the archival data urgently under certain circumstances, using this mode can greatly reduce the time required and increase the efficiency.
    • Standard mode: Restoration can be completed generally in 3 to 5 hours.
    • Batch mode: If your need for the archival data is not urgent, this mode can help retrieve massive amounts of data generally in 5 to 12 hours with the lowest cost.

    Replica Validity Period: Set in how many days the replica should automatically expire and be deleted. The value range is 1 to 365 days. After the object is successfully restored, you can click Restore again to change the validity period of the replica in the pop-up window.

  5. Click OK after the configuration items are set, and the object restoration will start. You can click Details to enter the object details page and check whether the restoration has been completed.

  6. After confirming that the object has been successfully restored, you can click Restore again to modify the validity period of its replica.

  7. Enter the object details page where you can access, download, and do more with the object.
