Hello @ypkkhatri

Here's an example snippet from one of my projects.

public boolean backup() {

    Properties properties = new Properties();
    properties.setProperty(MysqlExportService.JDBC_CONNECTION_STRING, dataSourceProperties.getUrl());
    properties.setProperty(MysqlExportService.DB_USERNAME, dataSourceProperties.getUsername());
    properties.setProperty(MysqlExportService.DB_PASSWORD, dataSourceProperties.getPassword());

    properties.setProperty(MysqlExportService.PRESERVE_GENERATED_ZIP, "true");
    properties.setProperty(MysqlExportService.ADD_IF_NOT_EXISTS, "true");

    String basePath = getClass().getProtectionDomain().getCodeSource().getLocation().getFile();
    File tempFile = new File(basePath, "/backup");

    properties.setProperty(MysqlExportService.TEMP_DIR, tempFile.getPath());
    MysqlExportService mySqlExportService = new MysqlExportService(properties);
    try {
        mySqlExportService.export();
        storageService.storeBackupFile(mySqlExportService.getGeneratedZipFile());
        return true;
    } catch (Exception e) {
        logger.error("Error Occurred in DatabaseBackupService: " + e.getLocalizedMessage());
        e.printStackTrace();
        return false;
    } finally {
        mySqlExportService.clearTempFiles(false);
    }
}

I configured the properties PRESERVE_GENERATED_ZIP to true. What this means is that when I call the mySqlExportService.export(); method, the generated zip file will be preserved and I can access it as java.io.File object.

Which is exactly what I did here storageService.storeBackupFile(mySqlExportService.getGeneratedZipFile());

In my case, the StorageService makes use of the AWS S3 SDK to upload the generated zip file to an S3 bucket.

Here is the implementation of that storeBackupFile() method:

public void storeBackupFile(File file) {

    if(!Objects.isNull(file)) {
        String newFileName = RandomStringUtils.randomAlphanumeric(5) + "_" + file.getName();
        AmazonS3 s3 = s3Factory();
        String bucketName = storageProperties.getAwsS3BucketName() + "/backup";

        Try.of(() -> s3.putObject(
                new PutObjectRequest(bucketName, newFileName, new FileInputStream(file), null)
                        .withCannedAcl(CannedAccessControlList.PublicRead)))
                .onFailure(e -> logger.error("Error Storing Object to S3: " + e.getLocalizedMessage())).get();
    }
}

I hope this helps you.

Cheers
