Replication

[poxin]

Is there any sort of replication option in Proxmox that would mimic functionality in Hyper-V? Would love to be able to enable replication for a VM from one proxmox cluster to another across geographical locations and simply flip a switch to do a failover.

Within a PVE cluster this is certainly doable, enable ZFS replication for a VM (or put it on a shared storage) and when you hit the "migrate" button, it will be moved over to another node.

Across clusters, this is currently not possible. You can only move VMs by making a backup and restoring it on the remote cluster.

not completely correct, you could use pve-zsync for this

Would it be possible to combine both ZFS Storage Replication and pve-zsync for a single VM?

For instance, we have a 'main' site with a 3-node ZFS cluster (2 full nodes and a small node for HA) using Storage Replication so we have High Availability for the VM

Next i would like to have some Disaster Recovery option for the same VM on a remote site using a fourth node (not a member of 3-node cluster) using pve-zsync.

This would be the best of both worlds, High Availability and Disaster Tolerance.
