If you are a political activist, don't backup your files to Dropbox og GDrive, unless it's data you are happy to allow the government to look into. Better to host the files yourself, encrypted with a one-time-pad, for which you have the matching pad with you in a microSD card.

Then, upon reaching your destination, and knowing that no one had access to your random bits in the one-time-pad, download your documents from home, and decrypt it.

No amount of processing power by the NSA will be able to help them get your files, and the only way the bits of your documents pass through the internet, is if you can confirm that the key to decrypt the file hasn't been touched.
