Restoring a Specific Archive Object Version

If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see the API Reference.

You can call ObsClient.restoreObject to restore an Archive object version by specifying versionId.

This example specifies versionId to restore Archive object destobjectname in destbucketname as a Standard object.

The example code is as follows:

// Hard-coded or plaintext AK and SK are risky. For security purposes, encrypt your AK and SK before storing them in the configuration file or environment variables. In this example, the AK and SK are stored in environment variables. Before running the code in this example, configure environment variables ACCESS_KEY_ID and SECRET_ACCESS_KEY_ID.
// Obtain an AK/SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
String ak = System.getenv("ACCESS_KEY_ID");
String sk = System.getenv("SECRET_ACCESS_KEY_ID");
String endPoint = "https://your-endpoint";
// Create an ObsClient instance.
ObsClient obsClient = new ObsClient(ak, sk, endPoint);

RestoreObjectRequest request = new RestoreObjectRequest("bucketname", "objectname", 1);
// Restore a versioned object at an expedited speed.
request.setRestoreTier(RestoreTierEnum.EXPEDITED);
request.setVersionId("versionid");
obsClient.restoreObject(request);
