Mirroring Samba Shares

I have 2 Rockstor servers (VMs) running at different sites. They are paired for replication. These servers also function as Samba servers for users at their respective site. BTRFS Send/Receive works as expected.

Question:
I was wondering if there’s any way to use btrfs to mirror the content of a share on Server1 to Server2? Btrfs send/receive in of itself is for archiving/backup and does not seem to offer any synchronizing/mirroring feature.
