How do you store and backup your photos ?

Doesn't it also depend on which and when future generations will/might want to access them? I don't have children or many nieces and nephews. My solution will be to de-clutter and pass on the physical, truly historical stuff, inherited from my parents, to whichever cousin is interested in them. Then it's their problem how to transmit them down the generations As for our renovation here and the making of the garden, they'll be available on HDD for potential heirs or buyers. As shiney wrote above, although a year by year record of the garden is useful and makes for interesting browsing to the gardener, it's unlikely to be of interest to anyone else.

 

I’ve got all my precious actual photographs locked up securely, in a portable metal filing cabinet. Hopefully they would survive any fires that may happen. As long as I have some of all the family members and some of my ancestors, I am happy to tap away on iphone and ipad of anything else and not be too worried about deleting them if they impact on the storage. To me, there’s nothing like handling a photo and “ seeing” the image, a little like handling an actual book rather than read a digital one.
My late father had a cine camera which he used all the time and so accrued boxes and boxes of film. I got some of them transferred digitally a long time ago. Only trouble is now, when we view them we have found that some of them are beginning to degrade! Don’t know why but we’ll keep them anyway. It does get a little upsetting though to see some members of the family, alive and well, who are now deceased, including my late father. Not reached the point yet where I can watch it for too long.

 

Like others here I store my images on computer and an external backup drive. My reasoning is - if I lose them it's my own stupid fault but if the whole lot were lost having been stored on a cloud, I'd never forgive myself. Also there are family images I prefer to keep private (as much as that's possible) on computer.

Forget the MP3 @noisette47 and hang on to those, they are all making a comeback. Vinyl is well under way and the others are now following suit.

 

The only trouble with that approach is that you need space to store it all and so many appliances to actually be able to listen to them I wish I was more 'selling inclined' as I'm sure they'd be valuable to someone. What I value most now is portability, being able to use the same medium from room to room and in the car or when out and about. Streaming seems to be the answer to that, as long as you're prepared to pay for it!

 

Never understood why vinyl is making a come back.
My loft has a lot of warped LPs.
