Download File From S3 Bucket

Amazon S3 Bucket. Amazon Simple Storage Service (Amazon S3) provides organizations with affordable and scalable cloud storage. Amazon S3 buckets can be pre-configured in GoAnywhere and then used as file repositories for trading partners. Workflows in GoAnywhere can also connect to Amazon S3 resources to upload, download and manage documents. And/or to upload to a Neo4j S3 buck anonymously run: Shell. Copy to Clipboard. $ aws s3 cp file s3:///file -acl=bucket-owner-full-control -no-sign-request. Replacing with the name of the AWS S3 instance, file with the name of the file on your server, and bucketName with the name of the bucket.

There are some s3 applications/tools which recognize versioning feature and either allow you to download one versioned object at a time or download all current revision of all objects inside your bucket.

1. For example when you use AWS CLI

You can list all objects along with its version ID using CLI command:

Example Output:

And then use the get-object command while specifying the version ID to download that particular object:

Example Output:

2. When you use application like S3 Browser you can download all current versions of all objects as shown here in the screenshots.

Select the bucket --> right click on Versions menu --> Download

If your requirement is to Download ALL versions (current + old versions) of ALL objects inside your bucket, you may use the scripted approach

The following script is tested with Wasabi to achieve this use case:

  • Make sure you have installed AWS SDK boto3 and click package for python on your CLI before running the script
  • Note that this code example discusses the use of Wasabi's us-east-1 storage region. To use other Wasabi storage regions, please use the appropriate Wasabi service URL as described here

Execution syntax for the above program:

Here are the outputs:

1. The bucket has multiple versions of different files inside a 'download-versions-bucket' bucket, the below command is listing all of those along with its Version ID



Example output:

2. Listing based on prefixes:

From the entire files, you can choose to list files based on prefix matching, in this example we are listing all objects that has 'Wasabi' as prefix and only listing those files


Example output:

I would like to grab a file straight of the Internet and stick it into an S3 bucket to then copy it over to a PIG cluster. Due to the size of the file and my not so good internet connection downloading the file first onto my PC and then uploading it to Amazon might not be an option.

Is there any way I could go about grabbing a file of the internet and sticking it directly into S3?

Download the data via curl and pipe the contents straight to S3. The data is streamed directly to S3 and not stored locally, avoiding any memory issues.

As suggested above, if download speed is too slow on your local computer, launch an EC2 instance, ssh in and execute the above command there.

For anyone (like me) less experienced, here is a more detailed description of the process via EC2:

  1. Launch an Amazon EC2 instance in the same region as the target S3 bucket. Smallest available (default Amazon Linux) instance should be fine, but be sure to give it enough storage space to save your file(s). If you need transfer speeds above ~20MB/s, consider selecting an instance with larger pipes.

  2. Launch an SSH connection to the new EC2 instance, then download the file(s), for instance using wget. (For example, to download an entire directory via FTP, you might use wget -r ftp://name:[email protected]/somedir/.)

  3. Using AWS CLI (see Amazon's documentation), upload the file(s) to your S3 bucket. For example, aws s3 cp myfolder s3://mybucket/myfolder --recursive (for an entire directory). (Before this command will work you need to add your S3 security credentials to a config file, as described in the Amazon documentation.)

  4. Terminate/destroy your EC2 instance.


[2017 edit]I gave the original answer back at 2013. Today I'd recommend using AWS Lambda to download a file and put it on S3. It's the desired effect - to place an object on S3 with no server involved.

[Original answer]It is not possible to do it directly.

Why not do this with EC2 instance instead of your local PC? Upload speed from EC2 to S3 in the same region is very good.

regarding stream reading/writing from/to s3 I use python's smart_open

You can stream the file from internet to AWS S3 using Python.
