Rowan wonders if USB thumb drives are becoming obsolete like so many other data drives before it. Leo says that no format will last forever, but there's still plenty of life left in USB. We need to keep an eye on how technology progresses and transfer the data over when the time comes, though. Rowan will likely be able to get an adapter for USB-C, which is the current standard. The other thing he can do is use an open source backup, like TAR, which will make the backup easily transferrable. The best way is to go into the cloud, though. He should have both.
