我注意到似乎没有从AWS管理控制台下载整个s3桶的选项。

有什么简单的方法可以把所有东西都装进我的桶里吗?我正在考虑使根文件夹公共,使用wget抓取它,然后再次使它私有,但我不知道是否有更简单的方法。

使用awscli下载/上传文件到s3总是更好。同步将帮助您恢复没有任何麻烦。

aws s3 sync s3://bucketname/ .

Windows User need to download S3EXPLORER from this link which also has installation instructions :- http://s3browser.com/download.aspx Then provide you AWS credentials like secretkey, accesskey and region to the s3explorer, this link contains configuration instruction for s3explorer:Copy Paste Link in brower: s3browser.com/s3browser-first-run.aspx Now your all s3 buckets would be visible on left panel of s3explorer. Simply select the bucket, and click on Buckets menu on top left corner, then select Download all files to option from the menu. Below is the screenshot for the same:

然后浏览文件夹以下载特定位置的bucket 点击OK,下载就开始了。

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

试试这个命令:

aws s3同步您的bucketnamedirectory您的localdirectory

例如,如果你的桶名是myBucket,本地目录是c:\local,那么:

aws s3 sync s3://myBucket c:\local

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
    private static void dBConnection() {
    app.setAwsCredentials(CONST.getAccessKey(), CONST.getSecretKey());
    conn = new AmazonS3Client(app.getAwsCredentials());
    app.setListOfBuckets(conn.listBuckets());
    System.out.println(CONST.getConnectionSuccessfullMessage());
    }

    private static void downloadBucket() {

    do {
        for (S3ObjectSummary objectSummary : app.getS3Object().getObjectSummaries()) {
            app.setBucketKey(objectSummary.getKey());
            app.setBucketName(objectSummary.getBucketName());
            if(objectSummary.getKey().contains(CONST.getDesiredKey())){
                //DOWNLOAD
                try 
                {
                    s3Client = new AmazonS3Client(new ProfileCredentialsProvider());
                    s3Client.getObject(
                            new GetObjectRequest(app.getBucketName(),app.getBucketKey()),
                            new File(app.getDownloadedBucket())
                            );
                } catch (IOException e) {
                    e.printStackTrace();
                }

                do
                {
                     if(app.getBackUpExist() == true){
                        System.out.println("Converting back up file");
                        app.setCurrentPacsId(objectSummary.getKey());
                        passIn = app.getDataBaseFile();
                        CONVERT= new DataConversion(passIn);

                    }
                }
                while(app.getObjectExist()==true);

                if(app.getObjectExist()== false)
                {
                    app.setNoObjectFound(true);
                }
            }
        }
        app.setS3Object(conn.listNextBatchOfObjects(app.getS3Object()));
    } 
    while (app.getS3Object().isTruncated());
}

/---------------------------- 扩展方法 -------------------------------------/

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

//list all S3 buckets
public static void listAllBuckets(){
    for (Bucket bucket : app.getListOfBuckets()) {
        String bucketName = bucket.getName();
        System.out.println(bucketName + "\t" + StringUtils.fromDate(bucket.getCreationDate()));
    }
}

//Get the contents from the auto back up bucket
public static void listAllBucketContents(){     
    do {
        for (S3ObjectSummary objectSummary : app.getS3Object().getObjectSummaries()) {
            if(objectSummary.getKey().contains(CONST.getDesiredKey())){
                System.out.println(objectSummary.getKey() + "\t" + objectSummary.getSize() + "\t" + StringUtils.fromDate(objectSummary.getLastModified()));
                app.setBackUpCount(app.getBackUpCount() + 1);   
            }
        }
        app.setS3Object(conn.listNextBatchOfObjects(app.getS3Object()));
    } 
    while (app.getS3Object().isTruncated());
    System.out.println("There are a total of : " + app.getBackUpCount() + " buckets.");
}

}

当在Windows,我的首选GUI工具这是CloudBerry Explorer免费软件 Amazon S3。它有一个相当精致的文件资源管理器和类似ftp的界面。
