SD cards by mail makes sense to me if they are traveling. And I doubt anyone would like the way I do things. I would copy the files to a laptop and let them transfer to my SFTP server in the background. This means I still have a local copy in case something goes wrong in the transfer or the SD card is damaged. Hopefully there is a safe place to lock up the laptop that still gives it some internet. Get a really cheap laptop as they are often stolen from travelers. There are SFTP clients for cell phones but they are all horrible in my opinion. Why SFTP? Trivial to set up a VM at Linode, DigitalOcean, Vultr, OVH, wherever and have storage in seconds. Also means some other company like Facebook isn't scanning / copying my files and claiming ownership of them or holding them hostage in some strange format.
