Snowball transfer failures.

Snowball transfer failures can occur due to various reasons, affecting the process of transferring data between your on-premises environment and AWS using the Snowball device. Here are some common causes and steps to address Snowball transfer failures:

1. Check Snowball Status:
   • Verify the status of the Snowball device in the AWS Snowball console. Ensure it's powered on, connected, and available for data transfer.
2. Review Snowball Documentation:
   • Familiarize yourself with the AWS Snowball documentation, including the specific requirements and steps for transferring data using Snowball.
3. Verify Connectivity and Network Configuration:
   • Ensure that your on-premises environment has the necessary network connectivity to communicate with the Snowball device. Confirm that firewalls and security groups allow the required traffic.
4. Check Data Source:
   • Verify that the data source (e.g., file systems, databases) from which you're transferring data is accessible and that there are no issues with permissions or connectivity.
5. Check Data Source Compatibility:
   • Ensure that the data source is compatible with Snowball and that you're using the appropriate tools or methods for transferring data.
6. Verify Data Integrity and Format:
   • Ensure that the data you're attempting to transfer is in the correct format and is not corrupted. Use tools to validate data integrity.
7. Review Data Transfer Jobs:
   • In the Snowball console, review the data transfer jobs to check for any error messages or status updates that might provide insights into the failure.
8. Check for Data Transfer Errors:
   • Monitor the Snowball client logs or console for any specific error messages related to the data transfer. Address any reported errors.
9. Check Snowball Client Configuration:
   • Review the configuration settings of the Snowball client software on your on-premises system. Ensure it's correctly configured to communicate with the Snowball device.
10. Verify Snowball Unlock Code:
    • Ensure that you're using the correct unlock code for the Snowball device. The unlock code is required to access the device.
11. Monitor for AWS Service Health Issues:
    • Check the AWS Service Health Dashboard for any reported issues with the Snowball service.
12. Consider Snowball Edge:
    • If you're dealing with large amounts of data or need additional computing capabilities, consider using a Snowball Edge device which offers more resources.
13. Contact AWS Support:
    • If you've gone through these steps and are still experiencing transfer failures, consider reaching out to AWS Support for further assistance.

Remember to also refer to the AWS Snowball documentation and best practices for guidance on troubleshooting specific to your use case.
