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 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 sample code is as follows:

<?php
// Import the dependency library.
require 'vendor/autoload.php';
// Import the SDK code library during the installation with the source code.
// require 'obs-autoloader.php';
// Declare the namespace.
use Obs\ObsClient;
use Obs\ObsException;

// Create an ObsClient instance.
$obsClient = new ObsClient([
    // Obtain an AK/SK pair using environment variables (recommended) or import an AK/SK pair in other ways. Using hard coding may result in leakage.
    // 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.
    'key' => getenv('ACCESS_KEY_ID'),
    'secret' => getenv('SECRET_ACCESS_KEY'),
    'endpoint' => 'https://your-endpoint',
]);

// Restore an Archive object.
try {
    $resp = $obsClient->restoreObject([
        'Bucket' => 'destbucketname',
        'Key' => 'destobjectname',
        'VersionId' => 'versionid',
        'Days' => 1,
        // Restore an object version at an expedited speed.
        'Tier' => ObsClient::RestoreTierExpedited
    ]);

    printf("RequestId:%s\n", $resp['RequestId']);
} catch (ObsException $e) {
    // If the operation fails, obtain the exception details.
    printf("RestoreObjectFailed: Status:%d, Code:%s, Message:%s\n",
        $e->getStatusCode(), $e->getExceptionCode(), $e->getExceptionMessage());
} finally {
    // Close ObsClient to release resources.
    $obsClient->close();
}

Repeated restorations from the Archive storage class extend the restoration's validity period. Note that you will be billed for each restoration.
