Downloading an entire S3 bucket?

Question

I noticed that there does not seem to be an option to download an entire s3 bucket from the AWS Management Console.

Is there an easy way to grab everything in one of my buckets? I was thinking about making the root folder public, using wget to grab it all, and then making it private again but I don't know if there's an easier way.

Answer 1

Using the AWS Management Console(AMC) to download an entire S3 bucket isn't straightforward, but there are better ways than your WGET approach. Here's the easiest method:

Use the AWS CLI

1. Install AWS CLI (if you haven't already): Download the AWS CLI and set it up on your system.

2. Configure AWS CLI: Run AWS configure to provide your credentials and set the region.

3. Download the entire bucket: Use the following command in bash:

   aws s3 cp s3://bucket-name /local/path --recursive

Replace bucket-name with your S3 bucket's name and /local/path with the directory where you want the files.

This approach is secure, and efficient, and avoids making the bucket public.

Answer 2

AWS S3 Sync is definitely your best option for downloading everything from your bucket, but if you prefer a graphical interface, tools like Cyberduck or Mountain Duck are great alternatives. These tools let you easily browse and download from S3 buckets, including bulk downloads. They do require setting up your AWS credentials, but they offer a more intuitive, user-friendly way to manage your files.

Answer 3

If the folder is public and you don't want to have to go through the configure steps, you can use the --no-sign-request option along with the s3 sync command to download the contents of the bucket:

aws s3 sync --no-sign-request s3://bucket_name/prefix/ <path to local folder>

Answer 4

100% works for me, i have download all files from aws s3 backet.

1. Install AWS CLI. Select your operating system and follow the steps here: Installing or updating the latest version of the AWS CLI

2. Check AWS version: aws --version

3. Run config command: aws configure

4. aws s3 cp s3://yourbucketname your\local\path --recursive

Eg (Windows OS): aws s3 cp s3://yourbucketname C:\aws-s3-backup\yourbucketname --recursive

Answer 5

I was also searching this to download multiple files from s3 bucket but haven't found the solution.

After some research and experiments, I tried below command and it's working

aws s3 cp s3://spebucket ./ --recursive

spebucket: is the bucket name

./ is the main folder where you have to download all the files I have used the aws s3 cp command with the --recursive flag to copy multiple files and directories recursively from a specified S3 bucket to your local directory.

Make sure while you run above command then you have to inside your folder then you can use the ./ in the above command

Answer 6

just use aws s3 sync command to download all the contents of the bucket. eg : aws s3 sync s3://<bucker name> to <destination/path> note: do aws configure before proceeding

Answer 7

Multiple Approaches to this, Preferred way would be using CLI.

1. Download the AWS CLI.
2. Configure it using your secret and access keys.
3. Now use the below commands within the AWS CLI.

 1. aws s3 cp s3://YourWholeBucketName YourLocalFolderName --recursive   |--> This will download the complete S3 Bucket
 2. aws s3 cp s3://YourWholeBucketName/FolderName YourLocalFolderName --recursive   |--> This will download the specific folder within your S3 Bucket

Answer 8

there are three options allow to download files or folders from S3 bucket:

• Option 1: Using AWS console
• Option 2: Using AWS cli
• Option 3: Using AWS SDK

---

About option 1:

• Navigate to the file's location within the bucket.
• Select the file by clicking on it.
• Click the "Download" button from the top menu.
• The file will be downloaded to your local machine. About option 2: Using the following command:

aws s3 cp s3://bucket-name/file-path local-file-path
# or 
aws s3 cp s3://bucket-name/folder-path local-folder-path --recursive

About option 3: In this case I am using boto3

import boto3
import os

def download_folder_from_s3(bucket_name, folder_name, local_path):
    s3 = boto3.client('s3')

    try:
        response = s3.list_objects_v2(Bucket=bucket_name, Prefix=folder_name)
        for obj in response.get('Contents', []):
            file_name = obj['Key']
            local_file_path = os.path.join(local_path, os.path.basename(file_name))
            s3.download_file(bucket_name, file_name, local_file_path)
            print(f"File '{file_name}' downloaded to '{local_file_path}'")
    except Exception as e:
        print(f"Error downloading folder: {e}")

# Replace with your actual bucket name, folder name, and local path
bucket_name = 'your-bucket-name'
folder_name = 'techvuehub-folder/'
local_path = './downloaded-files/'

if not os.path.exists(local_path):
    os.makedirs(local_path)

download_folder_from_s3(bucket_name, folder_name, local_path)

Download AWS CLI to Download S3 Bucket Data

Step 1: Install the AWS CLI

If you haven't installed the AWS CLI already, you can follow the instructions in the AWS CLI User Guide for your specific operating system: https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-quickstart.html

Step 2: Configure AWS CLI Open a command prompt or terminal.

aws configure

AWS Access Key ID [None]: <your_access_key>

AWS Secret Access Key [None]: <your_secret_key>

Default region name [None]: <YourBucketRegion>

Default output format [None]: json

Step 3: Download files from an S3 bucket

`aws s3 cp s3://<bucket-name>  --recursive`

Note: Ensure that the AWS CLI user or role associated with your credentials has the necessary permissions to access and download objects from the specified S3 bucket.

Answer 10

AWS SDK API is only the best option for uploading entire folder and repository to AWS S3 and to download entire AWS S3 bucket locally.

To upload whole folder to AWS S3: aws s3 sync . s3://BucketName

To download whole AWS S3 bucket locally: aws s3 sync s3://BucketName .

You can also assign path like BucketName/Path for particular folder in AWS S3 bucket to download.

Answer 11

In addition to the suggestions for aws s3 sync, I would also recommend looking at s5cmd.

In my experience I found this to be substantially faster than the AWS CLI for multiple downloads or large downloads.

s5cmd supports wildcards so something like this would work:

s5cmd cp s3://bucket-name/* ./folder

Answer 12

You just need to pass --recursive & --include "*" in the aws s3 cp command as follows: aws --region "${BUCKET_REGION}" s3 cp s3://${BUCKET}${BUCKET_PATH}/ ${LOCAL_PATH}/tmp --recursive --include "*" 2>&1

Answer 13

Here is a summary of what you have to do to copy an entire bucket:

1. Create a user that can operate with AWS s3 bucket

Follow this official article: Configuration basics

Don't forget to:

• tick "programmatic access" in order to have the possibility to deal with with AWS via CLI.
• add the right IAM policy to your user to allow him to interact with the s3 bucket

2. Download, install and configure AWS CLI

See this link allowing to configure it: https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-quickstart.html

You can use the following command in order to add the keys you got when you created your user:

$ aws configure
AWS Access Key ID [None]: <your_access_key>
AWS Secret Access Key [None]: <your_secret_key>
Default region name [None]: us-west-2
Default output format [None]: json

3. Use the following command to download content

You can a recursive cp commande, but aws sync command is f:

aws s3 sync s3://your_bucket /local/path

• To see what would be the dowloaded files before really do the download, you can use the --dryrun option.
• To improve speed, you can adjust s3 max_concurrent_requests and max_queue_size properties. See: http://docs.aws.amazon.com/cli/latest/topic/s3-config.html
• You can exclude/include some files using --exclude and --include options. See: https://docs.aws.amazon.com/cli/latest/reference/s3/

For example, the below command will show all the .png file presents in the bucket. Replay the command without --dryrun to make the resulting files be downloaded.

aws s3 sync s3://your_bucket /local/path --recursive --exclude "*" --include "*.png" --dryrun

Answer 14

AWS CLI is the best option to download an entire S3 bucket locally.

1. Install AWS CLI.

2. Configure AWS CLI for using default security credentials and default AWS Region.

3. To download the entire S3 bucket use command

   aws s3 sync s3://yourbucketname localpath

Reference to AWS CLI for different AWS services: AWS Command Line Interface

Answer 15

You can do this with MinIO Client as follows: mc cp -r https://s3-us-west-2.amazonaws.com/bucketName/ localdir

MinIO also supports sessions, resumable downloads, uploads and many more. MinIO supports Linux, OS X and Windows operating systems. It is written in Golang and released under Apache Version 2.0.

Answer 16

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

is a great answer, but it won't work if the objects are in storage class Glacier Flexible Retrieval, even if the the files have been restored. In that case you need to add the flag --force-glacier-transfer .

Answer 17

You can use sync to download whole S3 bucket. For example, to download whole bucket named bucket1 on current directory.

aws s3 sync s3://bucket1 .

Answer 18

When in Windows, my preferred GUI tool for this is CloudBerry Explorer Freeware for Amazon S3. It has a fairly polished file explorer and FTP-like interface.

Answer 19

Another option that could help some OS X users is Transmit.

It's an FTP program that also lets you connect to your S3 files. And, it has an option to mount any FTP or S3 storage as a folder in the Finder, but it's only for a limited time.

Answer 20

If you use Firefox with S3Fox, that DOES let you select all files (shift-select first and last) and right-click and download all.

I've done it with 500+ files without any problem.

Answer 21

use boto3 to download all objects in a bucket with a certain prefix

import boto3

s3 = boto3.client('s3', region_name='us-east-1', 
                     aws_access_key_id=AWS_KEY_ID, 
                     aws_secret_access_key=AWS_SECRET)

def get_all_s3_keys(bucket,prefix):
    keys = []

    kwargs = {'Bucket': bucket,Prefix=prefix}
    while True:
        resp = s3.list_objects_v2(**kwargs)
        for obj in resp['Contents']:
             keys.append(obj['Key'])

        try:
            kwargs['ContinuationToken'] = resp['NextContinuationToken']
        except KeyError:
            break

        return keys

def download_file(file_name, bucket,key):
    file=s3.download_file(
    Filename=file_name,
    Bucket=bucket,
    Key=key)
    return file

bucket="gid-folder"
prefix="test_"
keys=get_all_s3_keys(bucket,prefix):

for key in keys:
     download_file(key, bucket,key)
   
 

Answer 22

It's always better to use awscli for downloading / uploading files to s3. Sync will help you to resume without any hassle.

aws s3 sync s3://bucketname/ .

Answer 23

The answer by @Layke is good, but if you have a ton of data and don't want to wait forever, you should read "AWS CLI S3 Configuration".

The following commands will tell the AWS CLI to use 1,000 threads to execute jobs (each a small file or one part of a multipart copy) and look ahead 100,000 jobs:

aws configure set default.s3.max_concurrent_requests 1000
aws configure set default.s3.max_queue_size 100000

After running these, you can use the simple sync command:

aws s3 sync s3://source-bucket/source-path s3://destination-bucket/destination-path

or

aws s3 sync s3://source-bucket/source-path c:\my\local\data\path

On a system with CPU 4 cores and 16GB RAM, for cases like mine (3-50GB files) the sync/copy speed went from about 9.5MiB/s to 700+MiB/s, a speed increase of 70x over the default configuration.

Answer 24

I've done a bit of development for S3 and I have not found a simple way to download a whole bucket.

If you want to code in Java the jets3t lib is easy to use to create a list of buckets and iterate over that list to download them.

First, get a public private key set from the AWS management consule so you can create an S3service object:

AWSCredentials awsCredentials = new AWSCredentials(YourAccessKey, YourAwsSecretKey);
s3Service = new RestS3Service(awsCredentials);

Then, get an array of your buckets objects:

S3Object[] objects = s3Service.listObjects(YourBucketNameString);

Finally, iterate over that array to download the objects one at a time with:

S3Object obj = s3Service.getObject(bucket, fileName);
            file = obj.getDataInputStream();

I put the connection code in a threadsafe singleton. The necessary try/catch syntax has been omitted for obvious reasons.

If you'd rather code in Python you could use Boto instead.

After looking around BucketExplorer, "Downloading the whole bucket" may do what you want.

Answer 25

You've many options to do that, but the best one is using the AWS CLI.

Here's a walk-through:

1. 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.

2. Configure AWS CLI:

   

   Make sure you input valid access and secret keys, which you received when you created the account.

3. 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.

Answer 26

If you use Visual Studio, download "AWS Toolkit for Visual Studio".

After installed, go to Visual Studio - AWS Explorer - S3 - Your bucket - Double click

In the window you will be able to select all files. Right click and download files.

Answer 27

For Windows, S3 Browser is the easiest way I have found. It is excellent software, and it is free for non-commercial use.

Answer 28

To download using AWS S3 CLI:

aws s3 cp s3://WholeBucket LocalFolder --recursive
aws s3 cp s3://Bucket/Folder LocalFolder --recursive

To download using code, use the AWS SDK.

To download using GUI, use Cyberduck.

Answer 29

I've used a few different methods to copy Amazon S3 data to a local machine, including s3cmd, and by far the easiest is Cyberduck.

All you need to do is enter your Amazon credentials and use the simple interface to download, upload, sync any of your buckets, folders or files.

Answer 30

AWS CLI

See the "AWS CLI Command Reference" for more information.

AWS recently released their Command Line Tools, which work much like boto and can be installed using

sudo easy_install awscli

or

sudo pip install awscli

Once installed, you can then simply run:

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

For example:

aws s3 sync s3://mybucket .

will download all the objects in mybucket to the current directory.

And will output:

download: s3://mybucket/test.txt to test.txt
download: s3://mybucket/test2.txt to test2.txt

This will download all of your files using a one-way sync. It will not delete any existing files in your current directory unless you specify --delete, and it won't change or delete any files on S3.

You can also do S3 bucket to S3 bucket, or local to S3 bucket sync.

Check out the documentation and other examples.

Whereas the above example is how to download a full bucket, you can also download a folder recursively by performing

aws s3 cp s3://BUCKETNAME/PATH/TO/FOLDER LocalFolderName --recursive

This will instruct the CLI to download all files and folder keys recursively within the PATH/TO/FOLDER directory within the BUCKETNAME bucket.
