As Anton has described in his first post in this thread, you can either have two jobs pointing to different repositories (local and remote) or one local backup job and rsync syncing backups to remote site.
Many users feedback that rsync is not effective as it has to read the whole VM at both ends to know the difference before it can sync it over whereby Veeam Replication can skip this, thus Veeam replication will be much faster than using rsync. True?
What is the technical challenge here that prevent Veeam from able to do both backup and replication with just 1 snapshot and 1 read on the same VM?
foggy wrote:Nobody is talking about preference here. It's all about your backup strategy, but we like to say that backup is not a backup until you have at least 3 copies of it. It's quite a common practice to have replicas for short term retention and good RTO (immediate failover) and backups at both local and remote sites for a much longer (and less regular) retention (space-efficient data archive).
What is the reason for having at least 3 copies of backup to consider a complete backup?
For replicas at remote site, how does Veeam deal with remote subnet when restoring so that local users can still access the replicas as if these VMs appear to be original VMs running at local site?

In this environment, do I also need a proxy and repository server at each site to perform backup and replication?
Single Veeam B&R server is sufficient, but you do need to have proxy servers and repositories at each location for efficient backup and replication.[/quote]
I do not have a huge environment, just 2 ESXi hosts at HQ and 3 ESXi at DC (Data Center). If I need to backup VMs in both HQ and DC to one another, what is the bare minimum of servers I need to deploy? Are 3 sufficient as listed below or do I also need to deploy Repository Servers at both ends as well?
1 Veeam B&R at HQ
1 Proxy at HQ
1 Proxy at DC
