My Synology NAS is set up as RAID, so there’s redundancy built in.

Then I have daily backups to an external drive (automatic, so there’s no intervention).

In addition to (automatic) daily encrypted cloud backup (which I’m looking for an alternative due to rising costs). Ideally, I’d love to set up a second, smaller NAS somewhere else to offset the cloud backup costs.

Then I have a monthly backup on physical media kept secured outside of my home.

But my NAS handles way more than just photos and video, so this low effort is really covering all kinds of data.

I made the switch to self-hosting in part to reduce subscription costs of various services, and I’m sure that by now my setup has paid for itself.
