You just finished setting up all your services and it works fine - how do you now prepare for eventual drive failure?

I know that for data storage the best bet is a NAS and RAID1 or something in that vein, but what about all the docker containers you are running, carefully configured services on your rpi, installed *arr services on your PC, etc.?...

  • Most systems are provisioned in proxmox with terraform.
  • Configuration and setup is handled via ansible playbooks after the server is available. 2.a) Do NOT make changes on the server without updating your ansible scripts - except during troubleshooting. 2.b) Once troubleshooting is done delete and re-create the VM from scratch using only scripts to ensure it works.
  • VM storage is consider to be ephemeral. All long-term data/config that can’t be re-created with ansible is stored on an NFS server with a RAID5 dive configuration.
  • NFS server is backed-up nightly to backblaze using duplicacy.
  • Any other non-VM systems like personal laptops and the like are backed up nightly to the file-server using rsnapshot. Those snapshots are then backed up to backblaze using duplicacy.

    Great summary. How does work the provision with terraform? Do you have some guide? Is possible to provision LXC/VM on proxmox with ansible instead?

    I use the bpg/proxmox module to manage proxmox with terraform.

    LXC was pretty straight forward. Use the proxmox_virtual_environment_container module and set parameters.

    Basically I have an image that is based on a cloudinit image for Ubuntu (which I create and upload to proxmox with Ansible - but it wouldn’t be hard to do manually in case of a disaster recovery). I then clone that image to create new VMs using the proxmox_virtual_environment_vm module.
