I run a lot of tech, containerized workloads in AWS, home firewalls running on protectli boxes for all my family around the country, wireless controllers to run APs for my family around the country, but as I got older one thing I stopped rolling my own instance of was data backups. My data backs up to OneDrive and iDrive, so two copies of my data. My wife has access to both via shared credentials in a 1password folder that she knows how to access and uses regularly.

As I got older and I had a family, the pictures of our kids, wills, financial records, insurance documents are all just too important. Every service that holds my data is paid annually for less than $200/year total and auto renews. She could call either company and prove ownership if she ever did need help getting access. Also, I can easily share folders to her.

It's funny how getting older makes you think of the sorts of issues enterprise teams have. Don't implement solutions where you will be one deep, have a succession plan, and complexity is the enemy. All the tech I run now is fun and helpful, but can be replaced with a trip to BestBuy. The data and pictures however must be easy to retrieve for her.

So I don't have a good self hosted solution for you other than to say that at some point it's ok to change your strategy. And if you are worried about privacy, you can encrypt subsets of your data locally before it is backed up.
