I’m trying to plan a better backup solution for my home server. Right now I’m using Duplicati to back up my 3 external drives, but the backup is staying on-site and on the same kind of media as the original. So, what does your backup setup and workflow look like? Discs at a friend’s house? Cloud backup at a commercial provider? Magnetic tape in an underground bunker?

    I use Backblaze B2 for one offsite backup in “the cloud” and have two local HDDs. Using restic with rclone as storage interface, the whole thing is pretty easy.

    A cronjob makes daily backups to B2, and once per month I copy the most current snapshot from B2 to my two local HDDs.

    I have one planned improvement: Since my server needs programmatic access to B2, malware on it could wipe both the server and B2, leaving me with the potentially one-month old local backups. Therefore I want to run a Raspberry Pi at my parents’ place that mirrors the B2 repository daily but is basically air-gapped from the server. Should the B2 repository be wiped, the Raspberry Pi would still retain its snapshots.
