Setting up AWS CLI and dumping a S3 bucket


AWS CLI (command line interface) is very useful when you want to automate certain tasks. This post is about dumping a whole S3 bucket from the command line. This could be for any purpose, such as creating a backup.

First of all, if you don’t already have it installed, you’ll need to download and install the AWS CLI. More information here:

To configure AWS CLI, type the command:

aws configure

It will ask for credentials: the Access Key ID, and the Access Secret Key. More information on how to set up a key is here:

And that’s it! You now have the power of manipulating your AWS environment from your command line.

In order to dump a bucket, you’ll need to first make sure that the account belonging to the AWS Key you generated has read access to the bucket. More on setting up permissions in S3 here:

To dump the whole contents of an S3 bucket, you can use the following command:

aws s3 cp –quiet –recursive s3:///

This will copy the entire contents of the bucket to your local directory. As easy as that!
