Context and considerations

The Cold Archive storage class is an archival storage class. Also existing on its own as a dedicated product at OVHcloud (bucket-level granularity), Cold Archive is now also available as an Object Storage class in a general-purpose Object Storage container.

Objects in a Cold Archive storage class must be restored before they are available for download. Moreover, the Cold Archive storage class has a minimum storage duration and additional fees to consider:

  • The minimum storage duration for Cold Archive is 180 days. If an object is deleted during this period, an additional charge will be applied (prorated cost of storing the object for the full 180 days).
  • When a restoration request is made, users are asked to set a period of time (in days) during which the requested objects are available to download and are billed upfront at the Standard class rate.
  • Once a restoration request is made, it is not possible to add another restoration request with a shorter period of time. The first request can't be preempted.
  • If you are using multipart upload (MPU), you need to know that in-progress multipart parts are billed at Standard class rate until you complete the upload.
  • There are no storage overhead charges.

Restore process can take up to 48 hours depending on the size of the objects. Download action is then available when the restore process is done.

You can restore an object in the Cold Archive storage class by using the , the Amazon S3 REST API or CLI, or by using OVHcloud APIs.

Restoring an archived object

AWS CLI
OVHcloud API

In the left-hand menu of your Public Cloud project, click Object Storage under Storage, then click the name of your bucket in the Containers tab.

In the Objects tab, click the Restore button on the row of the object you want to restore. In the Restore object window, enter the Number of days available (how long the restored copy stays available for download), then click Restore.

You can also monitor the status of your restoration in the list of objects: the object shows Restoration in progress, then Available until followed by a date. To keep the restored copy available longer, click the edit icon next to this date, enter a new number of days and click Extend.
