Datentransport per Netzwerk ist ja schön und gut, aber man soll nicht die Bandbreite der alternativen Vergessen:

Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway.—Tanenbaum, Andrew S. (1996). Computer Networks. (via wikipedia)

Das gilt auch für den Datentransport von/zu Amazon S3:

AWS Import/Export accelerates moving large amounts of data into and out of AWS using portable storage devices for transport. [...] you can now have your data quickly loaded from Amazon S3 onto a portable storage device and have it sent to you or your partners. For significant data sets, AWS Import/Export is often faster than Internet transfer and more cost effective than upgrading your connectivity.—E-Mail to S3 customers, received 14.8.2009, also on the web
