Restoring Archived Objects

Last updated: 2021-08-13 11:57:33

    Overview

    You can restore an object from the ARCHIVE or DEEP ARCHIVE storage class through the COS console. The restoration operation will create a copy of the object in the STANDARD storage class. You can read, download, or perform other operations on the copy within a specified time period, after which the copy will expire automatically. For more information, please see Storage Class Overview.

    Note:

    If you restore objects from ARCHIVE, the object copy will be billed at STANDARD rates. If you restore objects from DEEP ARCHIVE, the object copy will be charged request fees at the marked unit price, and traffic fees at STANDARD rates. For more information, please see Product Pricing.

    Directions

    1. Log in to the COS console.

    2. In the left sidebar, click Bucket List to go to the bucket list page.

    3. Locate the bucket where the object resides and click the bucket name to go to the bucket management page.

    4. In the left sidebar, choose File List to go to the file list page.

    5. Locate the object to restore and click Restore in the Operation column.

      To restore multiple archived objects at a time, select them all in the object list, and click Restore from the More Actions drop-down list at the top.

    6. In the pop-up window, configure the restoration mode and the validity period (in days) of the copy.

      The parameters are described as follows:

      • Restoration Mode: expedited, standard, or batch mode.
        • Expedited mode: This is the fastest mode. Archived files can be restored within 1-5 minutes. If you need to access your archival data urgently, you can use this mode to greatly reduce the restoration time. Please note that expedited mode is not available for DEEP ARCHIVE.
        • Standard mode: Files can be restored from ARCHIVE within 3-5 hours, and from DEEP ARCHIVE within 12 hours.
        • Batch mode: This is the lowest-cost mode. If your need for the archival data is not urgent, this mode can usually restore massive amounts of data from ARCHIVE within 5-12 hours, and from DEEP ARCHIVE within 48 hours, both with an ultra-low cost.
          Note:

          The QPS of data restoration requests is limited to 100.

      • Validity: 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.
    7. Click OK. The object enters the restoration process.
      During this process, you can click Details to go to the object details page to check the restoration progress.

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

      You can go to the object details page where you can access, download, and do more with the object.
