As I now run my own Mastodon instance where anyone can request registration, there are goals to achieve with it. For example, the Mastodon Server Covenant. There is "Daily backups" among other requirements, and today's story is about that. It involves Proxmox Backup Server, Ansible, and Tailscale as the three pillars of "Daily Matrix and Mastodon backups with zero downtime."
Circumstances forced me to move all my self-hosted services to a location that does not depend on my living place. Someday, I hope I'll have all that hosted at home again, but now I want to describe my path of setting up a Proxmox VE on a Hetzner dedicated server together with Proxmox Backup Server and Tailscale with backups on Backblaze. This could look like a trivial task at first, but I faced some issues and obstacles I want to document here, for me to remember and for others to be informed.
I want to warn that this is not a full step-by-step guide. It is rather notes on the process and steps I followed.
