Currently, I have a 3 node Proxmox cluster with 6 kube nodes on it (3 masters, 3 workers). Lets me do things like migrate services off of a host so I can take it out, do upgrades/maintenance, and put it back without hearing about downtime from the family/friends.

For storage, I’ve got a Synology NAS with NFS setup and then the pods are configured to use that for their storage if they need it (So, Jellyfin, Immich, etc). I do regular backups of the NAS with rsync. So, if that goes down, I can restore or standup a new NAS with NFS and it’ll be back to normal.
