This article will give you a quick visual enhanced tutorial covering every step that is needed to save your valuable files to AWS S3. It will guide you on how to back up your data to AWS S3. S3 is an abbreviation of Simple Storage Service and provides multiple ways to upload a file or folder.
From the above-mentioned ways, I will explain How-To upload using the AWS CLI
To create a FREE AWS account go to https://aws.amazon.com/free/ and create your account. To follow this tutorial you need to have an account.
S3 will be used to store your backup. An S3 bucket can be created at https://s3.console.aws.amazon.com/s3/home. You have to choose a bucket name and can keep the default values except for encryption.
I would suggest that you enable default encryption

To create IAM Credentials to access your S3 bucket open your account menu (top right corner) and click Security Credentials

Now switch to Access keys (access key ID and secret access key) and create a new access key by clicking the button

Additionally, you can find much information about creating AWS access keys in the Amazon knowledge base:
Installing the AWS CLI can be done on Linux (and on Windows in the Ubuntu WSL 2 CLI) with
sudo apt-get install awscli
After the AWS CLI is installed check the version
aws --version
As I created this How-To I was using Windows with this version
 |
Now you can set your IAM credentials for your machine. Start the process to enter your credentials
aws configure
Type in your AWSAccess Key ID, AWSSecret Acces Key, a default region, and an output format. Confirm every line with . It should look like this:

Now you are ready to back up your files to your bucket. Two important commands can be used: Copy and Sync
Copy can be used to copy a file or folder to S3. It will overwrite files if they are already within your bucket. For copying a folder you have to use --recursive. The following command will copy a <SOURCE_FOLDER> to a DST_FOLDER in your YOUR_BUCKET_NAME within S3.
aws s3 cp --recursive <SRC_FOLDER> s3://BUCKET_NAME/DST_FOLDER/
With Sync you can keep the content of a folder on your machine in sync with the folder within your S3 bucket. The following command will sync your local SRC_FOLDER with your DST_FOLDER in the S3 bucket s3://BUCKET_NAME.
aws s3 sync <SRC_FOLDER> s3://BUCKET_NAME/DST_FOLDER/
