Related Operations

After versioning is configured for a bucket, you can go to the object details page, click the Versions tab, and then delete and download object versions, and extend the retention period of an object version.

1. In the bucket list, click the bucket you want to operate. The Overview page is displayed.
2. In the navigation pane, choose Objects.
3. In the object list, click the object you want to go to the object details page.
4. On the Versions tab page, view all versions of the object.
5. Perform the following operations on object versions:
   1. Download a desired version of the object by clicking Download in the Operation column.
      

      If the version you want to download is in the Cold storage class, restore it first.

   2. Permanently delete a version of the object by choosing Delete in the Operation column. The deleted object version cannot be recovered. If you delete the latest version, the most recent version will become the latest version.
      

      In a WORM-enabled bucket, if an object has no retention policy configured or its retention policy has expired, you can delete a desired object version on the object's Versions tab page. If an object version is within the retention period, it cannot be deleted.

   3. Locate the object version for which you want to extend the retention period, choose Extend Retention Period, and select a date. A retention period can be extended, but cannot be shortened.
