How to use PHP and Google Cloud Storage Transfer Service for file transfer and backup

With the advent of the big data era, data backup and migration should be indispensable skills for every enterprise. In addition to traditional backup methods such as disk cloning and tape backup, Google Cloud Storage Transfer Service is a fast, reliable, and affordable backup and migration method. In this article, we will explain how to use PHP and Google Cloud Storage Transfer Service for file transfer and backup.

1. Create and configure Google Cloud Storage Transfer Service

First, you need to create a new storage transfer job on the Google Cloud Platform console. Select Cloud Storage transfer on the console and follow the prompts to fill in the information about the storage transfer job. You need to provide the details of the source and target data repositories. You can specify to transfer data from a bucket, or you can choose to transfer data from Google Drive, Amazon S3, or other supported repositories.

In the process of creating a storage transfer job, you also need to specify the data transfer schedule, including daily, weekly, monthly, etc.

2. Use PHP to connect to the Google Cloud Storage Transfer Service

Once you have set up the storage transfer job, you can use PHP to transfer data to the source and target repositories. First, you need to set up authentication for the Google Cloud Storage Transfer Service.

To authenticate, you need to download the Google API PHP Client and start Composer, then add the following dependencies in the composer.JSON file.

"google/apiclient": "^2.7"

After adding the dependencies, you need to enable the Google Cloud Storage Transfer API in the Cloud Platform console. When enabling the API, you need to create a service account to authenticate to the Google Cloud Storage Transfer Service.

Next, you need to authorize the service account to your PHP file through some code, as shown below.

require 'vendor/autoload.php';

$client = new Google_Client();
$client->setApplicationName(' Storage Transfer');
$client->setScopes([

Google_Service_StorageTransfer::DEVSTORAGE_FULL_CONTROL,
Google_Service_CloudPlatform::CLOUD_PLATFORM,

]);
$client->setAuthConfig('path/to/your/auth/json/file.json ');

$service = new Google_Service_StorageTransfer($client);

?>

After authorizing the service account, you can use PHP to call Google Cloud Storage Transfer Service API.

3. Use Google Cloud Storage Transfer Service in PHP for file transfer and backup

The following is a code example of how to use PHP and Google Cloud Storage Transfer Service for file transfer and backup.

require 'vendor/autoload.php';

$client = new Google_Client();
$client->setApplicationName(' Storage Transfer');
$client->setScopes([

Google_Service_StorageTransfer::DEVSTORAGE_FULL_CONTROL,
Google_Service_CloudPlatform::CLOUD_PLATFORM,

]);
$client->setAuthConfig('path/to/your/auth/json/file.json ');

$service = new Google_Service_StorageTransfer($client);

//Set the conditions for transfer from the source Bucket
$srcConditions = new Google_Service_StorageTransfer_AwsS3Data();
$ srcConditions->setBucketName('my-first-bucket');
$srcConditions->setAwsAccessKey([

'accessKeyId' => 'xxxxxxxxxxxxx',
'secretAccessKey' => 'yyyyyyyyyyyyy',

]);

// Set the conditions for transmission, including Transfer scheme and transfer time
$transferSpec = new Google_Service_StorageTransfer_TransferSpec();
$transferSpec->setAwsS3DataSource($srcConditions);
$transferSpec->setGcsDataSink([

'bucketName' => 'my-target-bucket',

] );

$schedule = new Google_Service_StorageTransfer_Schedule();
$schedule->setScheduleStartDate([

'year' => 2021,
'month' => 12,
'day' => 30

]);
$schedule->setScheduleEndDate([

'year' => 2022,
'month' => 1,
'day' => 5

]);
$schedule->setStartTimeOfDay([

'hours' => 12,
'minutes' => 30,
'seconds' => 0,
'nanos' => 0

]);
$schedule->setEndTimeOfDay([

'hours' => 13,
'minutes' => 0,
'seconds' => 0,
'nanos' => 0

]);

$transferJob = new Google_Service_StorageTransfer_TransferJob();
$transferJob->setDescription('My Transfer Job Description');
$transferJob->setTransferSpec($transferSpec);
$ transferJob->setSchedule($schedule);
$transferJob->setStatus('ENABLED');

// Create a new storage transfer job
$createdJob = $service-> transferJobs->create($transferJob);

?>

In the example code above, we set up the source repository ('my-first-bucket') from Amazon S3 Transfer specifications and schedule to the Google Cloud Storage target repository ('my-target-bucket').

Summary

Google Cloud Storage Transfer Service is a very useful and flexible data backup and migration tool. Using PHP and the Google Cloud Storage Transfer Service, you can easily transfer data to various types of data repositories.
