Absolutely sinking feeling in my stomach: I've jut discovered that our local "cupboard" storage doesn't have any of my wife's photos or videos from 2020 to 2021.
The Nextcloud app on her phone was always temperamental, but it wasn't a big problem because stuff went to Google Photos too. Recently we reached the storage limit for Google, so I wanted to make sure everything was in the cupboard.
I reinstalled the Nextcloud app and it said it had backed up everything, so she deleted big videos from Google Photos. But of course, really old stuff wasn't on her phone any more!
I really hope we've got copies somewhere of her videos.
