It used to be you could find a box of photos or keepsakes that you inherited to look back on how things were or when you were a kid. Now, most of that is stored on phones, and most parents probably don’t think to share or save them in a way to be passed down in the future.
Better yet, back up to your computer, that is backed up to an external hard drive, that is copied to a trustworthy cloud somewhere. Always good to have duplicates should something happen.
I lost about 12 years of pictures after getting rid of OneDrive (getting rid of Microsoft cuz I maxed out the 1TB anyway), and no joke a few weeks later on my personal server, 4 out of 8 hard drives failed. Thinking it was my raid card, I replaced them, couldn’t get it to function. Apparently a storm that we had fried some components and not others, and I swear I had duplicates on some old offline drives, so when I installed those to restore, I did not have everything. Crushed my heart!! I bought a bunch of large flash drives specifically for photos and videos, and started to back up to those for historical purposes.
