Invest in more than one backup method
Diane May Levenick wrote an excellent article for Family Tree Magazine (updated a few months ago) detailing a five-step plan for backing up genealogy files. She recommends NOT relying on free sites (like social media) as a backup. Instead, she suggests a combination of methods, including remote cloud storage, to keep family history safe.
As Diane recommends, I keep my digitized materials safe by backing up on iCloud, setting my Mac to do a TimeMachine backup every hour (using an external hard drive I can take with me if needed), and putting important files on a separate high-capacity USB drive. Or two USBs! They're inexpensive and portable.
My family history photo books are one way I'm sharing family history NOW so what I've learned about our ancestors won't be lost. Printed copies are in multiple hands because LOCKSS (lots of copies keep stuff safe). The more people who have copies, the better the chance that info will survive in our family for future generations.
All the photos in those books and all old family photos from the early 20th century are digitized. I've shared them via USB and email over the years. I have a 1917 photo album from my late father-in-law that has been scanned but I plan to turn it into a photo book this year to provide full captions and context for future generations. The album itself is in an archival box but the album pages are fragile so making a photo book will make the story accessible to all for the long term.
I continue to post bite-sized ancestor bios on multiple sites. These don't preserve original photos or documents, but they do keep alive the names/dates/lives of ancestors in the family tree. And serve as cousin bait!
