Either my PC tower or my backup drives (which are kept elsewhere in the house in the event of a fire to increase my chances of getting at least one of them out) - really should look at cloud backup.
If I was using cloud backups (therefore making my pictures & other stuff safe), it'd be the storage box that we keep my Daughter's stuff in, things she has made & got as she has grown up and other important stuff, only 5 years old but still a full box, that or the box(es) of old family photos that aren't digitalised, including our wedding album
