Data Compression: The Process server acts as a replication gateway. It receives replication data and optimizes it with caching, compression, and encryption.

Compression isnt used when replicating Hyper-V VMs to Azure. For compression a third-party appliance (eg. Riverbed) needs to be used.


Bandwidth Throttling: Bandwidth used for remote replication traffic can be limited. A maximum bandwidth applies to remote replication traffic from the Process Server in protection site to the recovery site (Kbps/Mbps). Minimum bandwidth is 512 Kbps; Maximum bandwidth is 1,023 Mbps. Throttling can be time-based by specifying time windows for Work Hours (24 hour clock) and Work Days.

In addition bandwidth can be throttled for a specifc VM by adjusting the UploadThreadsPerVM in the VMs registry. Default value is 4; Maximum value is 32.
