I have an external RAID 1 hard drive that I backup everything to every 6 months or so. Before someone points it out, the individual drives in the array have build dates that differ by at least a year. In addition; for really critical stuff only (accounting data, deeds, business contracts, access codes, software source code, etc.) I use micro SD cards for more frequent backups as needed. I have a cheap digital watch with a SD card holder that I 3D printed and built into the strap. The SD drive is encrypted with Bitlocker and it travels with me wherever I go. Basically, this really critical data is as safe as I am. I always make 2 copies of the SD drive and keep one in a fire proof safe. The key to the safe is revealed in my will which my lawyer has. Inside the safe is the decryt key to the SD card. A trusted relative also has the decrypt key.
