 This example creates a mirror of VM 100 (in the source cluster) as VM 10100 (in the destination cluster) using the ceph pool "data2" for storing all attached disks. It will keep 4 Ceph snapshots prior the latest (in total 5) and 8 snapshots on the remote cluster. It will keep the VM on the target Cluster locked to avoid an accidental start (thus causing split brain issues), and will do it even if the source VM is running. 
 
 The use case is that you might want to keep a cold-standby copy of a certain VM on another Cluster. If you need to start it on the target cluster you just have to unlock it with `qm unlock VMID` there.
@@ -146,6 +148,78 @@ Another usecase could be that you want to migrate a VM from one cluster to anoth
 
 To minimize downtime and achive a near-live Migration from one Cluster to another it's recommended to do an initial Sync of a VM from the source to the destination cluster. After that, run the job again, and add the --migrate switch. This causes the source VM to be shut down prior snapshot + transfer, and be restarted on the destination cluster as soon as the incremental transfer is complete. Using --migrate will always try to start the VM on the destination cluster.

 ## Things to check
 
 From Proxmox VE Hosts you want to backup you need to be able to ssh passwordless to all other Cluster hosts, that may hold VM's or Containers. This goes for the source and for the destination Cluster.
