TL;DR

This can be done by building a data pipeline manually, usually a Python script (you can leverage a tool as Apache Airflow for this). This process can take more than a full week of development. Or it can be done in minutes on Airbyte in three easy steps:

1. set up SFTP as a source connector (using Auth, or usually an API key)
2. set up S3 as a destination connector
3. define which data you want to transfer and how frequently

You can choose to self-host the pipeline using Airbyte Open Source or have it managed for you with Airbyte Cloud.

This tutorial’s purpose is to show you how.

What is SFTP

SFTP (Secure File Transfer Protocol) is a secure way to transfer files between two computers over the internet. It uses encryption to protect the data being transferred, making it more secure than traditional FTP (File Transfer Protocol). SFTP is commonly used by businesses and organizations to transfer sensitive data such as financial information, medical records, and personal data. It requires authentication using a username and password or public key authentication, ensuring that only authorized users can access the files. SFTP is also platform-independent, meaning it can be used on any operating system, making it a versatile and reliable option for secure file transfers.

What is S3

Amazon S3 (Simple Storage Service) is a cloud-based object storage service provided by Amazon Web Services (AWS). It is designed to store and retrieve any amount of data from anywhere on the web. S3 is highly scalable, secure, and durable, making it an ideal solution for businesses of all sizes. S3 allows users to store and retrieve data in the form of objects, which can be up to 5 terabytes in size. These objects can be accessed through a web interface or through APIs, making it easy to integrate with other AWS services or third-party applications. S3 also offers a range of features, including versioning, lifecycle policies, and access control, which allow users to manage their data effectively. It also provides high availability and durability, ensuring that data is always accessible and protected against data loss. Overall, S3 is a powerful and flexible tool that enables businesses to store and manage their data in a secure and scalable way, making it an essential component of many cloud-based applications and services.

Prerequisites

1. A SFTP account to transfer your customer data automatically from.
2. A S3 account.
3. An active Airbyte Cloud account, or you can also choose to use Airbyte Open Source locally. You can follow the instructions to set up Airbyte on your system using docker-compose.

Airbyte is an open-source data integration platform that consolidates and streamlines the process of extracting and loading data from multiple data sources to data warehouses. It offers pre-built connectors, including SFTP and S3, for seamless data migration.

When using Airbyte to move data from SFTP to S3, it extracts data from SFTP using the source connector, converts it into a format S3 can ingest using the provided schema, and then loads it into S3 via the destination connector. This allows businesses to leverage their SFTP data for advanced analytics and insights within S3, simplifying the ETL process and saving significant time and resources.

Methods to Move Data From SFTP to S3 

• Method 1: Connecting SFTP to S3 using Airbyte.
• Method 2: Connecting SFTP to S3 manually.

2. Click on the "Add Destination" button and select "S3" from the list of available connectors.

3. Enter your AWS access key ID and secret access key in the appropriate fields. If you don't have these credentials, you can generate them in the AWS console.

4. Choose the AWS region where you want to store your data.

5. Enter the name of the S3 bucket where you want to store your data. If the bucket doesn't exist yet, you can create it in the AWS console.

6. Choose the format in which you want to store your data (e.g. CSV, JSON, Parquet).

7. Configure any additional settings, such as compression or encryption, if desired.

8. Test the connection to ensure that Airbyte can successfully connect to your S3 bucket.

9. Save your settings and start syncing data from your source connectors to your S3 destination.

‍

Step 3: Set up a connection to sync your SFTP data to S3

Once you've successfully connected SFTP as a data source and S3 as a destination in Airbyte, you can set up a data pipeline between them with the following steps:

1. Create a new connection: On the Airbyte dashboard, navigate to the 'Connections' tab and click the '+ New Connection' button.
2. Choose your source: Select SFTP from the dropdown list of your configured sources.
3. Select your destination: Choose S3 from the dropdown list of your configured destinations.
4. Configure your sync: Define the frequency of your data syncs based on your business needs. Airbyte allows both manual and automatic scheduling for your data refreshes.
5. Select the data to sync: Choose the specific SFTP objects you want to import data from towards S3. You can sync all data or select specific tables and fields.
6. Select the sync mode for your streams: Choose between full refreshes or incremental syncs (with deduplication if you want), and this for all streams or at the stream level. Incremental is only available for streams that have a primary cursor.
7. Test your connection: Click the 'Test Connection' button to make sure that your setup works. If the connection test is successful, save your configuration.
8. Start the sync: If the test passes, click 'Set Up Connection'. Airbyte will start moving data from SFTP to S3 according to your settings.

Remember, Airbyte keeps your data in sync at the frequency you determine, ensuring your S3 data warehouse is always up-to-date with your SFTP data.

Method 2: Connecting SFTP to S3 manually.

Moving data from an SFTP server to Amazon S3 without third-party connectors or integrations requires using AWS services such as AWS S3, AWS EC2, and AWS CLI. 

Prerequisites:

• An SFTP server with data you want to transfer.
• An AWS account.
• An Amazon S3 bucket where you will store the data.
• An EC2 instance to act as an intermediary for the transfer.

Step 1: Set Up Your S3 Bucket

1. Log in to the AWS Management Console.
2. Navigate to the Amazon S3 service.
3. Create a new S3 bucket or use an existing one where you will store the data.some text
   • Click on "Create bucket".
   • Follow the prompts to configure the bucket settings (name, region, etc.).
   • Set the necessary permissions and policies for the bucket to ensure data can be written.

Step 2: Set Up Your EC2 Instance

1. Navigate to the EC2 Dashboard in the AWS Management Console.
2. Launch a new EC2 instance.some text
   • Choose an Amazon Machine Image (AMI) that suits your needs.
   • Select an instance type.
   • Configure instance details, such as network and IAM role (ensure the IAM role has permission to access S3).
   • Add storage if needed.
   • Configure security groups to allow SFTP and SSH access.
   • Review and launch the instance.
3. Connect to the instance using SSH.

Step 3: Install AWS CLI on EC2

1. Connect to your EC2 instance using SSH.
2. Update the package manager (e.g., sudo yum update for Amazon Linux or sudo apt update for Ubuntu).
3. Install AWS CLI using the package manager (e.g., sudo yum install awscli or sudo apt install awscli).

Step 4: Configure AWS CLI

1. Run aws configure on the EC2 instance.
2. Enter the AWS Access Key ID and Secret Access Key.
3. Specify the default region and output format.

Step 5: Transfer Data from SFTP to EC2

1. On the EC2 instance, install an SFTP client if not already available.
2. Connect to the SFTP server using the client (sftp username@sftp-server-address).
3. Navigate to the directory containing the data to transfer.
4. Use the get command to download the data to the EC2 instance (e.g., get datafile.txt).

Step 6: Upload Data from EC2 to S3

Use the AWS CLI to upload the data from the EC2 instance to the S3 bucket:
aws s3 cp /path/to/datafile.txt s3://your-bucket-name/path/in/bucket/

• Replace /path/to/datafile.txt with the path to the data file on your EC2 instance.
• Replace your-bucket-name with the name of your S3 bucket.
• Replace /path/in/bucket/ with the desired path in the S3 bucket.

Step 7: Verify Data Transfer

Check that the data has been successfully uploaded to S3:
aws s3 ls s3://your-bucket-name/path/in/bucket/

You can also verify the upload through the S3 console by navigating to the bucket and checking the contents.

Step 8: Clean Up

1. Once the transfer is verified, you can remove the data from the EC2 instance to free up space.
2. If the EC2 instance was only used for this transfer, consider stopping or terminating it to avoid incurring further costs.

Step 9: Automate the Process (Optional)

• For recurring transfers, you can write a script that automates steps 5 and 6.
• Set up a cron job or use AWS Lambda to schedule and run the script as needed.

Tips:

• Ensure the EC2 instance has the necessary IAM role with permissions to access both the SFTP server and the S3 bucket.
• Use secure methods to handle AWS credentials and avoid hardcoding them in scripts.
• Always verify the integrity of the data after transfer with checksums or hashes if possible.
• Monitor the AWS usage and costs associated with the EC2 instance and data transfer.

By following these steps, you can move data from an SFTP server to Amazon S3 manually.

Use Cases to transfer your SFTP data to S3

Integrating data from SFTP to S3 provides several benefits. Here are a few use cases:

1. Advanced Analytics: S3’s powerful data processing capabilities enable you to perform complex queries and data analysis on your SFTP data, extracting insights that wouldn't be possible within SFTP alone.
2. Data Consolidation: If you're using multiple other sources along with SFTP, syncing to S3 allows you to centralize your data for a holistic view of your operations, and to set up a change data capture process so you never have any discrepancies in your data again.
3. Historical Data Analysis: SFTP has limits on historical data. Syncing data to S3 allows for long-term data retention and analysis of historical trends over time.
4. Data Security and Compliance: S3 provides robust data security features. Syncing SFTP data to S3 ensures your data is secured and allows for advanced data governance and compliance management.
5. Scalability: S3 can handle large volumes of data without affecting performance, providing an ideal solution for growing businesses with expanding SFTP data.
6. Data Science and Machine Learning: By having SFTP data in S3, you can apply machine learning models to your data for predictive analytics, customer segmentation, and more.
7. Reporting and Visualization: While SFTP provides reporting tools, data visualization tools like Tableau, PowerBI, Looker (Google Data Studio) can connect to S3, providing more advanced business intelligence options. If you have a SFTP table that needs to be converted to a S3 table, Airbyte can do that automatically.

Wrapping Up

To summarize, this tutorial has shown you how to:

1. Configure a SFTP account as an Airbyte data source connector.
2. Configure S3 as a data destination connector.
3. Create an Airbyte data pipeline that will automatically be moving data directly from SFTP to S3 after you set a schedule

With Airbyte, creating data pipelines take minutes, and the data integration possibilities are endless. Airbyte supports the largest catalog of API tools, databases, and files, among other sources. Airbyte's connectors are open-source, so you can add any custom objects to the connector, or even build a new connector from scratch without any local dev environment or any data engineer within 10 minutes with the no-code connector builder.
