I've been doing the data storage tango for thirty years now, and the one constant is that everything requires maintenance or has to be moved to a different platform and software eventually. Today, everything is in Google Drive and Google Photos; about 600 GB worth of data and media. Maintenance consists of an annual Takeout ordeal with copies going on two different removable drives, one of which is stored in a so-called fireproof bag.
The fireproof bag also has my account/password list (printed out once a year), birth certificates, titles, and passports.
If you are the tech person in your family, think about what happens if you die. Will your family be able to figure out and maintain your system? Mine is far from perfect, but most of my family can figure out Google Drive.
Where do you guys live to need to store birth certificate in a fireproof bag?
I can just login into my government website with a digital identity provider and print one legally valid copy any time. Same for any identity related certificate.
Anywhere I've been in the US, getting a certified birth certificate (fancy paper with an embossed seal) will cost some money and take a week or more. The fireproof bag is just a convenient place to keep papers for which a scan is no substitute.
The fireproof bag also has my account/password list (printed out once a year), birth certificates, titles, and passports.
