## Multi-Cluster Georedundancy
Starting with PVC version 0.9.103, the system now supports online VM snapshot transfers between clusters. This can help enable a second georedundancy mode, leveraging a full cluster in two sites, between which important VMs replicate. In addition, this design can be used with higher-layer abstractions like service-level redundancy to ensure the optimal operation of services even if an entire cluster becomes unavailable. Service-level redundancy between two clusters is not addressed here.

Service-level redundancy between two clusters is not addressed here.
Multi-cluster redundancy eliminates most of the caveats of single-cluster georedundancy while permitting single-instance VMs to be safely replicated for hot availability, but introduces several additional caveats regarding promotion of VMs between clusters that must be considered before and during failure events.
