Overview

You can restore archived objects in the COS Console for further access and operations. For more information about object storage classes, see Storage Class.

The restoration operation will create a copy of the object in standard storage class, which can be read and downloaded. The object copy will be billed as a standard 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. Click File List, select a single object or multiple objects you want to restore, and click Restore under More Actions.
   
4. In the Restore Archived Objects pop-up window, configure the restoration mode and the validity period in days of the copy. The related configuration items are detailed below.
   • Recovery Mode: Standard, Expedited, or Batch.
     • Expedited mode: This is the fastest mode. Files below 256 MB can be restored in 1 to 5 minutes. When you need to access the archival data urgently, using this mode can greatly reduce the time required.
     • 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.
   • Validity: set the number of days after which the copy would 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 copy in the pop-up window.
