A well placed encrypted backup on two separately located microSD cards (in case mice eat the other), located within a few hundred meters of your actual residence, should be beyond the ability of common goons (ICE, cops, impatient FBI agents) to locate. They’d have to engage in long-term surveillance.
If curious kids find one, it’s still encrypted and you still have the other, and curious kids won’t take your primary data carrier by raiding your house either. You just replace the backup then and put it elsewhere.
Even 1 TB is arduous. Don’t back up your movie collection, let the feds have it if they want. Back up your code, correspondence and encryption keys. :)
