Local NAS with offsite backup is far more resilient than any physical item onsite. One house fire and that album goes up in smoke.

Some years back, I tried to take photos out of a random family album to scan them. The album was built so there was a plastic sheet in front of the photos, to hold them in place / protect them. Well, that sheet ended up ripping bits out of the photos, and it's glossy enough that I can't scan the photos through it. Be careful with assumptions of how long physical products last.

Also, books used to be printed on better paper; modern cheap books will not last as long as the old ones did. I have a couple of collector's edition books printed on acid-free paper...

:-) It's not like I'm using an old analog camera, or delete the files after printing.

It's just nice to a/ have an extra copy just in case and b/ it's more enjoyable/sentimental than looking at photos on a laptop, smartphone or TV.

At least my kids really enjoy it a lot. They liked to look at the albums my mom made from my pictures when they were between 2 and 5, still do today, even though they perfectly know how to navigate to all the photos on a tablet. That's when I decided to do it.
