Hi all;

As you know, when configuring Hyper-V Replica on a Replica Server, it able use to specify multiple primary servers. Right?

As I can specify which servers are trusted to replicate to replica server, why bother me to create a Trust Group  and join that primary servers to it? What is the primary purpose of creating Trust Group?

Hi Sir,

>> What is the primary purpose of creating Trust Group?

"How is this useful? Hyper-V Replica allows replication to continue seamlessly when virtual machines are migrated either on the primary server/cluster or Replica server/cluster. Hence the replication traffic for a given Replica virtual machine cannot be tied only to the server that enabled replication of the virtual machine. "

"Tag to group a set of such allowed primary servers into a trust zone (Security Tag). "
