My one other media type is “the cloud”.

I use hard drives, I can’t imagine trying to put something on a disk or something.

One thing I do recommend, I keep one unencrypted hard drive copy in the safest most hidden part of my house. This is in case encryption software disappears, or I just forget my encryption keys or something.

Other than that, one encrypted copy of files in a thumb drive in my wallet (selected files, not everything). One in my car. One in my firesafe. Then daily cloud backup.
