I just have it copied to an external HDD and also daily sync to cloud B2 storage (encrypted) while the main copy of the media lives on the SSD.

I never have to touch it unless there’s a failure… I should have a versioned backup on the HDD in that case. Unless there’s a fire or something and both are destroyed in which case I should be able to pull them from the cloud storage.

It’s all just automated cron jobs requires no effort on my part beyond setting it up.
