What are the Possibilities to Download Objects an entire S3 bucket to your Local?

Yes, we have options to download all the objects from an S3 bucket to your local machine. Before we do, make sure that the AWS-CLI package is installed in your local machine and configured with credentials are Access Key and Secret Key.

Install AWS-CLI Package:

Download the awscliv2.zip file using the curl command and extract it.

$ curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"



$ unzip awscliv2.zip

Install the package using the command below,

$ sudo ./aws/install -i /usr/local/aws-cli -b /usr/local/bin

After installed the package, check the version using the command below,

$ aws --version

Install AWS-CLI another method,

Alternatively, we have another option to install the awscli package which AWS recently released their Command Line Tools

$ sudo easy_install awscli

or

$ sudo pip install awscli

run config command and set the IAM role/user credentials,

$ aws configure

We have two options to copy the objects from S3 bucket to local machine, "CP" and "SYNC" and formats are here,
 
So, now we use the commands below,

$ aws s3 cp s3://bucket_name/ .  --recurisve



$ aws s3 sync s3://bucket_name/ .  

If you use the Windows command prompt execute the command below,

$ aws s3 cp s3://bucket_name D:\destination --recursive



$ aws s3 sync s3://bucket_name/  D:\destination\
