AWS Snowball is a data transfer service that enables users to move large amounts of data to and from Amazon Web Services (AWS) securely and efficiently. The Snowball appliance, which is a rugged, portable storage device, allows users to transfer data at speeds that would be impossible over the internet. This knowledge base will guide you through the AWS Snowball job creation process, covering everything from prerequisites to job management.

Understanding AWS Snowball

What is AWS Snowball?

AWS Snowball is designed for transferring large datasets typically in the range of terabytes to petabytes by shipping physical devices to your location. Once data is copied onto the device, it is shipped back to AWS, where the data is uploaded directly into Amazon S3. This service is particularly useful in scenarios where network bandwidth is limited or transferring large volumes of data over the internet is impractical.

Key Features

• High Speed Data Transfer: Snowball can transfer data at speeds up to 80 TB per day, significantly reducing the time required for data migration.
• Secure Data Handling: Data is encrypted both in transit and at rest. Each Snowball device is also tamper-resistant and includes security measures to prevent unauthorized access.
• Integrated with AWS Services: Snowball integrates seamlessly with AWS services, enabling users to easily upload data into Amazon S3, Amazon Glacier, or other AWS storage services.

 Use Cases

• Data Migration: Quickly transfer large amounts of data from on-premises storage to AWS.
• Disaster Recovery: Create backups of critical data and store them in AWS for disaster recovery.
• Data Archiving: Move infrequently accessed data to AWS for long-term storage.

Prerequisites for Using AWS Snowball

 AWS Account

You need an active AWS account with the necessary permissions to create and manage Snowball jobs. Make sure you have IAM (Identity and Access Management) permissions for AWS Snowball and access to Amazon S3.

Snowball Service Limits

• Region Availability: Ensure that Snowball is available in your desired AWS region. Check the AWS Regional Services List for the most current information.
• Job Limits: Be aware of the limits on the number of concurrent Snowball jobs and devices you can order in your account.

Security Configuration

• IAM Role: Create an IAM role that grants Snowball access to your S3 buckets. This role should have the required permissions for the actions you want to perform with the Snowball device.
• Encryption Key: Set up a customer-managed key in AWS KMS (Key Management Service) if you plan to use your own encryption keys for data transfer.

Creating an AWS Snowball Job

Creating a Snowball job involves several steps, including defining the job type, configuring the job details, and managing the job lifecycle.

 Accessing the AWS Snowball Console

1. Sign in to AWS Management Console: Use your AWS account credentials to log in.
2. Navigate to Snowball: In the console, type Snowball in the search bar and select it from the results.

 Choosing Job Type

When creating a Snowball job, you can choose between two main job types:

• Data Transfer: For transferring data from your on-premises environment to AWS (import).
• Data Export: For transferring data from AWS back to your on-premises environment (export).

Select the appropriate option based on your needs.

Configuring Job Details

 Job Settings

1. Specify Job Type: Choose between import or export job.
2. Select Service Type: For an import job, select the destination S3 bucket or Glacier. For export, specify the source bucket.

 Select an SNOWBALL Device Type

1. Choose Device Size: Select the size of the Snowball device based on your data transfer requirements. AWS offers different sizes, including 50 TB and 80 TB options.
2. Device Shipping Method: Choose how you want the device to be delivered (standard shipping or expedited shipping).

Set IAM Role

1. Choose IAM Role: Select the IAM role that has permissions to access the specified S3 bucket or Glacier.
2. Create a New Role (if needed): If you don't have an existing role, you can create one during this step.

Add Job Metadata (Optional)

You can add metadata to the job for tracking and organization purposes. This can include:

• Job Name: Provide a descriptive name for the job.
• Description: Optional field for additional details about the job.

 Review and Create Job

After configuring all job settings:

1. Review Job Details: Ensure all settings are correct and complete.
2. Create Job: Click the Create Job button to initiate the job creation process.

Receiving the Snowball Device

After job creation, AWS will prepare and ship the Snowball device to your specified address. You will receive an email notification with tracking information.

Using the Snowball Device

Unboxing and Setting Up the Device

Once the Snowball device arrives:

1. Unbox the Device: Carefully remove the Snowball device from its packaging.
2. Power On the Device: Connect the device to a power source and power it on.

Connecting to the Snowball Device

You can connect the Snowball device to your local network via Ethernet:

1. Network Connection: Connect an Ethernet cable from the Snowball device to your local network.
2. Accessing the Snowball Management Console: Use a web browser to access the device’s management interface, typically at the IP address provided in the documentation.

Transferring Data to the Snowball Device

Once connected, you can start transferring data:

1. Install the Snowball Client: Download and install the Snowball client from the AWS website to your local machine.
2. Authenticate: Use the provided credentials to log in to the Snowball device.
3. Transfer Data: Use the Snowball client to copy files and directories to the Snowball device. Monitor transfer progress through the client interface.

Finalizing Data Transfer

Once data transfer is complete:

1. Finalize the Job: In the Snowball management console, select the completed job and follow prompts to finalize the data transfer.
2. Eject the Device: Safely eject the Snowball device from your system.

Returning the Snowball Device

 Preparing the Device for Return

1. Power Off the Device: Shut down the Snowball device.
2. Repack the Device: Place the device back in the original shipping container, ensuring it is securely packed.

Scheduling Return Shipment

1. Create a Return Label: In the AWS Snowball console, generate a return shipping label.
2. Schedule Pickup: Arrange for the shipping carrier to pick up the device or drop it off at the designated shipping location.

Managing Snowball Jobs

Monitoring Job Progress

You can monitor the status of your Snowball jobs through the AWS Management Console:

• Job Status: View job status updates, including In Progress, Completed, or Failed.
• Job Details: Click on a job to view detailed logs and metrics regarding the data transfer.

Reviewing Data Transfer Logs

Data transfer logs provide insight into the data copied to the Snowball device:

• Logs Access: Access logs through the AWS Management Console or by using the Snowball client.
• Error Handling: Review logs for any error messages or warnings during the data transfer process.

Managing Multiple Jobs

If you have multiple Snowball jobs:

• Sort Jobs: Use filters in the console to sort jobs by status, type, or date.
• Manage Permissions: Ensure the correct IAM permissions are set for each job to prevent unauthorized access.

Security Considerations

Data Encryption

• In Transit Encryption: Data is automatically encrypted during transfer to ensure confidentiality.
• At Rest Encryption: Utilize AWS KMS to manage encryption keys for sensitive data stored in S3.

Physical Security

• Tamper Resistant Devices: Snowball devices are designed to resist tampering, ensuring data integrity during transport.
• Device Tracking: Use tracking features to monitor the shipping status of your Snowball device.

 Access Control

• IAM Policies: Implement strict IAM policies to control who can create and manage Snowball jobs.
• Audit Logs: Enable AWS CloudTrail to log all Snowball-related API calls for auditing purposes.

Best Practices for Using AWS Snowball

Optimize Data Transfer

• Data Deduplication: Remove duplicate files before transferring to minimize the amount of data sent.
• Compress Data: Consider compressing large files to reduce transfer size and time.

Automate Job Creation

• Use AWS SDKs: Automate job creation and management using AWS SDKs and CLI for efficient workflows.
• Integrate with CI/CD Pipelines: If applicable, integrate Snowball jobs into your CI/CD pipelines to.
