Protecting Data Using Server-Side Encryption with Amazon S3-Managed Encryption Keys (SSE-S3) in
the Amazon Simple Storage Service Developer Guide.
• In the US regions, Snowballs come in two sizes: 50 TB and 80 TB. All other regions have the 80 TB
Snowballs only. If you're using Snowball to import data, and you need to transfer more data than will
fit on a single Snowball, create additional jobs. Each export job can use multiple Snowballs.
• The default service limit for the number of Snowballs you can have at one time is 1. If you want to
increase your service limit, contact AWS Support.
• All objects transferred to the Snowball have their metadata changed. The only metadata that remains
the same is filename and filesize. All other metadata is set as in the following example: -rw-rw-
r-- 1 root root [filesize] Dec 31 1969 [path/filename]
Limitations on Transferring On-Premises Data with
a Snowball
The following limitations exist for transferring data to or from a Snowball appliance on-premises:
• Files must be in a static state while being copied. Files that are modified while they are being
transferred will not be imported into Amazon S3.
• Jumbo frames are not supported—that is, Ethernet frames with more than 1500 bytes of payload.
• When selecting what data to export, keep in mind that objects with trailing slashes in their names (/
or \) will not be transferred. Before exporting any objects with trailing slashes, update their names to
remove the slash.
• When using the Amazon S3 Adapter for Snowball with the AWS CLI to transfer data, note that the --
recursive option for the cp command is only supported for uploading data to a Snowball, not for
transferring data from a Snowball.
Limitations on Shipping a Snowball
The following limitations exist for shipping a Snowball:
• AWS will not ship a Snowball to a post office box.
• AWS will not ship a Snowball between non-US regions—for example, from EU (Ireland) to EU
(Frankfurt), or from Asia Pacific (Mumbai) to Asia Pacific (Sydney).
• Moving a Snowball to an address other than the one specified when the job was created is not allowed
and is a violation of the AWS Service Terms.
For more information on shipping, see Shipping Considerations for AWS Snowball (p. 73).
Limitations on Processing Your Returned Snowball
for Import
To connect your returned Snowball to one of our Snowball stations for import, the appliance must meet
the following requirements:
• The Snowball appliance must not be compromised. Except for the two access panels in the front and
the back, don't open the Snowball for any reason.
