Can I import data from a Hadoop Distributed File System to Snowball?
Using Snowball to Export Data

Yes. You can copy data from a HDFS cluster to Snowball using the Snowball CLI. To learn more, please refer to the Snowball documentation.
What is the Snowball export feature?
Using Snowball to Export Data
AWS Snowball | Storage
Export is a feature of Snowball that enables customers to export terabytes to petabytes of data from Amazon Simple Storage Service (Amazon S3) to on-premises storage.
How do I get my data from AWS with export?
Using Snowball to Export Data
AWS Snowball | Storage
To use Snowball Export simply sign in to the AWS Management Console, choose Snowball, and create an export job. As with an import job, you specify the region and buckets that you want to use. If you don’t want to export all of the data from a particular bucket, you can specify a beginning and ending S3 key range sorted in UTF-8 binary order to indicate what data should be exported. The key range that you choose, and all keys between them, are exported. Details on using the console can be found here.
How quickly can I access my exported data?
Using Snowball to Export Data
AWS Snowball | Storage
We typically start exporting your data within 24 hours of receiving your request, and exporting data can take as long as a week. Once the job is complete and the device is ready, we ship it to you using the shipping options selected when you created the job.
Can I pick up the Snowball from your data center so I don’t have to wait for shipping?
Using Snowball to Export Data
AWS Snowball | Storage
No. Although you can select one-day shipping, we do have to ship the Snowball to an address that you provide. We don’t have a way for you to pick up a Snowball from our data center.
Can I track the export data-writing progress while you prepare my Snowball?
Using Snowball to Export Data
AWS Snowball | Storage
Yes. You can see when we start provisioning a Snowball and get real-time updates as data is written to the device. As with import jobs, you can get notification when the provisioning is complete and when the device has been shipped.
Will AWS encrypt my data before copying it to the Snowball?
Using Snowball to Export Data
AWS Snowball | Storage
Yes. All data that is written is encrypted and the encryption keys for that data are never present on the Snowball.
How do I read my data from the Snowball when I receive the device?
Using Snowball to Export Data
AWS Snowball | Storage
Using the Snowball client, you can copy your data from the Snowball to local storage. The client decrypts your data when it reads it from the Snowball and writes the data to your local storage in the same format as the data was stored in Amazon S3.
How much data can I export?
Using Snowball to Export Data
AWS Snowball | Storage
There is almost no limit the amount of data you can export. If you want to export more data than can fit on one appliance, additional export jobs will be created automatically for you so that all of the data you select can be exported.
Can I retrieve data from more than one bucket?
Using Snowball to Export Data
AWS Snowball | Storage
Yes. You can select as many buckets as you want for export.
How are my Amazon S3 objects mapped to files when I copy them to my local storage?
Using Snowball to Export Data
AWS Snowball | Storage
Each key is copied to your device in a directory tree that starts with the bucket’s name. For example, if the key is “images/orange.jpg” and the bucket is “fruit” then the object is saved to /fruit/images/orange.jpg. Meta data associated with each object is not copied to your storage device.
Can I export data that is in the Amazon Glacier storage class?
Using Snowball to Export Data
AWS Snowball | Storage
No. Before Amazon Glacier data can be exported it needs to be restored to Amazon S3 using the S3 Lifecycle Restore feature.
Do I get a log of what was exported?
Using Snowball to Export Data
AWS Snowball | Storage
Yes. For each job, import or export, a log of the files that were copied and those that could not be copied is generated and available from the Snowball console.
