    Object Storage Service:Real-time access of Archive objects

    Last Updated:Sep 11, 2023

    If you enable real-time access of Archive objects for an Object Storage Service (OSS) bucket, you can access Archive objects in the bucket without the need to restore the Archive objects. Real-time Archive data access requires less time to retrieve data and incurs higher fees than accessing Archive data after data restoration. This feature is suitable for occasional access to extremely infrequently accessed data. This topic describes how to enable and use real-time access of Archive objects.

    Prerequisites

    • A bucket is created. For more information, see Create a bucket.

    • A RAM user that has the following permissions exists: oss:PutBucketArchiveDirectRead and oss:GetBucketArchiveDirectRead. For more information, see Common examples of RAM policies.

    Scenarios

    Real-time access of Archive objects is suitable for scenarios that involve data lakes, cloud photo albums, media asset archiving, and medical images. Real-time access of Archive objects meets the requirements for real-time access of data that is extremely infrequently accessed while reducing the overall storage costs.

    Fees

    After you enable real-time access of Archive objects for a bucket, when you access Archive objects that are not restored in the bucket, you are charged Archive data retrieval fees based on the size of accessed Archive data (RetrievalDataArchiveDirect). When you access Archive objects that are restored in the bucket, you are not charged Archive data retrieval fees. For more information, see Data processing fees.
