I do an automated nightly backup via restic to Backblaze B2. Every month, I manually run a script to copy the latest backup from B2 to two local HDDs that I keep offline. Every half a year I recover the latest backup on my PC to make sure everything works in case I need it. For peace of mind, my automated backup includes a health check through healthchecks.io, so if anything goes wrong, I get a notification.
It's pretty low-maintenance and gives a high degree of resilience:
restic has been very solid, includes encryption out of the box, and I like the simplicity of it. Easily automated with cron etc. Backblaze B2 is one of the cheapest cloud storage providers I could find, an alternative might be Wasabi if you have >1TB of data.
How much are you backing up? Admittedly backblaze looks cheap but at $6 Tb leaves me with $84 pcm or just over $1000 per year.
I'm seriously considering a rpi3 with a couple of external disk in an outbuilding instead of cloud
Oh, I think we're talking different orders of magnitude here. I'm in the <1TB range, probably around 100GB. At that size, the cost is negligible.
