Good day,

Im new here in proxmox, can I ask how can I copy all my proxmox VE and data center to a new physical server? I will make a 2nd physical server as backup to prevent downtime.

Currently installed a proxmox on a HP proliant server with raid5.
Planning to replicate it in another physical server (maybe purchase a clone desktop as 2nd domain server)

Please help me.

You have multiple options. In any of them you would start with installing the new ProxmoxVE server.
Afterwards do one of this:
  • Proxmox Datacenter Manager (still alpha) or qm remote-migrate on the command line to migrate between the old node and the new node: https://pve.proxmox.com/pve-docs/qm.1.html
  • Backup and restore every VM/LXC on the old and restore on the to the new one.
  • Create a cluster out of both nodes, migrate the VMs to the new node, remove old node from the cluster.
I would go with the first or second option or a combination:
Backup everything, then first try remote-migrate. If this doesn't work out do a restore.
