你可以使用s3cmd下载你的桶:

s3cmd --configure
s3cmd sync s3://bucketnamehere/folder /destination/folder

您可以使用另一种名为rclone的工具。这是Rclone文档中的一个代码示例:

rclone sync /home/local/directory remote:bucket

您有许多选项可以做到这一点，但最好的是使用AWS CLI。

下面是一篇简介:

Download and install AWS CLI in your machine: Install the AWS CLI using the MSI Installer (Windows). Install the AWS CLI using the Bundled Installer for Linux, OS X, or Unix. Configure AWS CLI: Make sure you input valid access and secret keys, which you received when you created the account. Sync the S3 bucket using: aws s3 sync s3://yourbucket /local/path In the above command, replace the following fields: yourbucket >> your S3 bucket that you want to download. /local/path >> path in your local system where you want to download all the files.

Aws同步是完美的解决方案。它不是双向的。从源头到目的地只有一条路。此外，如果你在bucket中有很多项目，首先创建s3端点将是一个好主意，这样下载就会更快(因为下载不是通过互联网进行的，而是通过内部网进行的)，而且不收费

100%为我工作，我已经下载了所有的文件从aws s3备份。

安装AWS CLI。选择您的操作系统并按照以下步骤操作:安装或更新AWS CLI的最新版本 检查AWS版本:AWS——version

执行config命令:aws configure

Aws s3 cp s3://yourbucketname你的\本地\路径——递归

例如(Windows操作系统):aws s3 cp s3://yourbucketname C:\aws-s3-backup\project-name——recursive

这里有一些东西可以下载所有桶，列出它们，列出它们的内容。

    //connection string

                if(app.getObjectExist()== false)
                {
                    app.setNoObjectFound(true);

//Unzip bucket after download 
public static void unzipBucket() throws IOException {
    unzip = new UnZipBuckets();
    unzip.unZipIt(app.getDownloadedBucket());
    System.out.println(CONST.getFileUnzippedMessage());

//Get the contents from the auto back up bucket
public static void listAllBucketContents(){

    System.out.println("There are a total of : " + app.getBackUpCount() + " buckets.");
}

}

aws s3 sync s3://<source_bucket> <local_destination>

是一个很好的答案，但它不会工作，如果对象在存储类冰川灵活检索，即使文件已经恢复。在这种情况下，你需要添加标志——force-glacier-transfer。
