Proxmox Cluster Disaster Recovery Implementation and Cluster Replication Plan

[vslknsgr]

Greetings Team,

There is a possibility that we may need to implement disaster recovery for the Proxmox cluster is create the HCI with ceph.

For instance, there is a cluster currently operational in Location A with a 3-node setup. I aim to replicate this cluster in Location B.

Both locations have identical server configurations.

What is your question ?

You can use https://docs.ceph.com/en/latest/rbd/rbd-mirroring/

We need to set the DR for the Cluster running A location to B location

We need to set the DR for the Cluster running A location to B location

This is still not a question. What do you want to achieve and what issues/problems/questions are you having?

We need to set up live replication for our Disaster Recovery (DR) site.


Example:
The current production cluster is located at Site A (SAC). We want to establish the DR site at Site B (TAX). There is a point-to-point network connection between the two data centers with 10GB


Is it possible to achieve this setup using Proxmox?

With ZFS this would be possible with pve-zsync https://pve.proxmox.com/wiki/PVE-zsync
I remember at some point somebody mentioned that Ceph also has such a feature but I can't remember any details and lack personal experience.
I googled but found only this one: https://pve.proxmox.com/wiki/Ceph_RBD_Mirroring
Maybe somebody of the Ceph experts here can chime in how to achieve this?

A storage-agnostic method might be to have one ProxmoxBackupServer on each site and sync their backups between them. So in case of a disaster, you would live-restore the Backup on the second location: Thus the VM would start and already run while the restore is continued.

This kind of setup needs "Distributed Storage" ( not Shared Storage) with realtime sync.
Something called VSAN (example: StarWind VSAN, Petasan ).
Storage level doing realtime sync, exporting the block-storage over ISCSI,NVMEof,FC to the Hypervisors's VM disk.
