Same, I use Restic + Backrest (plus monitoring on Healthchecks, self-hosted + Prometheus/AlertManager/Pushover), with some decent structure - local backups every half-an-hour to raid1, every hour a backup to my old NAS, every day a backup to FTP in Helsinki, and once a week some backups to Backblaze (via Restic). Gives me local backups, observability, remote backups spread across different providers - seems quite safe :) I highly recommend to everyone figuring out a good backup strategy, takes a day or two.

Edit: on top of that I've built a custom one-page monitoring dashboard, so I see everything in one place (https://imgur.com/B3hppIW) - I'll opensource, it's decent architecture, I just need to cleanup some secrets from Git history...
