We backed our computer files onto an external hard drive that we put into our bank safety deposit box. Smaller backups might fit on smaller devices these days.

BRILLIANT!
Um.... does anyone know.... are safety deposit boxed an emp cage by any chance? Just wondering.
Here is what the US Department of Homeland Security sayes:
https://info.publicintelligence.net/DHS-FacilitiesGuidelinesEMP.pdf
"Use heavy-duty aluminum foil or inexpensive faraday bags/cases. For small electronics, you can put these in a plastic or paper bag or other insulating material and then wrap the item with an outer layer of heavy-duty aluminum foil. If power or data cables are permanently connected to the equipment, you should also place these inside the bag before wrapping the item with aluminum foil. You should ensure the aluminum foil completely covers the item and that all seams overlap. If possible, protect the equipment with two or more complete layers of aluminum foil."
"If you decide to use a faraday bag, be sure that it is not just a standard Mylar food bag which provides little protection. Metal trash cans do not usually provide reliable EMP protection for items placed inside of them, unless they have been modified to block radio waves from entering through the gaps in the lid, handles, and sometimes at the base."
"Microwave ovens can serve as expedient faraday cages for small electronics, but should be tested with a cell phone and/or AM/FM radio to see if there is reception inside of the oven (obviously, these “ovens” should never be turned “on” with equipment inside)".
"In general, small handheld electronics are relatively resilient to EMP effects, unless they have long antennas or power cords attached , and so the need for faraday cages is of secondary importance"
Will you even receive warning before the EMP? Better be fast with the foil! There is a good deal more information in thi unclassified publication and some photos of EMP Damage. If there is an Omaha centered blast neither of us is in a happy place.....
Not sure, but they are metal. My readings into the matter - very limited- indicate that a metal trash can fully lined with cardboard will emp proof electronic stuff.
