I'm looking at a solution for friends who will be traveling the world to let them back up their data (mainly photos, videos, so multiple GBs per month). They would love to ensure they do not lose them, for instance, due to bad luck or customs scrutiny.
How would you do this?
Does it still make sense to send SD cards by mail? Is there any service provider on this?The main challenge is that they do not expect to have much internet connectivity during their travel.
