Troubleshooting Connection Problems
Troubleshooting for a Standard
Snowball
The following can help you troubleshoot problems that you might have with an AWS Snowball
(Snowball). If you're having trouble establishing a connection to a Snowball, see Why can’t my AWS
Snowball appliance establish a connection with the network? in the AWS Knowledge Center.
Troubleshooting Connection Problems
The following can help you troubleshoot issues you might have with connecting to your Snowball.
• Routers and switches that work at a rate of 100 megabytes per second won't work with a Snowball.
We recommend that you use a switch that works at a rate of 1 GB per second (or faster).
Troubleshooting Data Transfer Problems
If you encounter performance issues while transferring data to or from a Snowball, see Performance
for AWS Snowball (p. 34) for recommendations and guidance on improving transfer performance.
The following can help you troubleshoot issues you might have with your data transfer to or from a
Snowball.
• Data can't be transferred into the root folder of the Snowball. If you're having trouble transferring
data into the Snowball, make sure that you're transferring data into a folder on the Snowball that is
not the root folder.
• For security purposes, data transfers must be completed within 90 days of the Snowball being
prepared. After 90 days, the Snowball becomes locked to additional on-premises data transfers. If the
Snowball becomes locked during a data transfer, return the Snowball and create a new job to transfer
the rest of your data. If the Snowball becomes locked during an import job, we can still transfer the
existing data on the Snowball into Amazon S3.
• Objects transferred onto Snowballs have a maximum key length of 933 bytes. Key names that include
characters that take up more than one byte each still have a maximum key length of 933 bytes. When
determining key length, you include the file or object name and also its path or prefixes. Thus, files
with short file names within a heavily nested path can have keys longer than 933 bytes. The bucket
name is not factored into the path when determining the key length. Some examples follow.
