5. Hyper-V Replica, Whats New ?
Seamless Upgrade
Cross version, WS2012 > WS2012 R2
No need to re-IR
Replication Frequency
30sec, 5min & 15min frequency
Provides flexibility
Recovery Points
Retian up to 24 recovery points (up from 16)
Longer retention period
Linux Guest OS support
Integrated with non-Windows OS
Provides file-system consistent snapshots
Extended replication
Site A > Site B > Site C
5min & 15min replication interval
Performance improvments
Lower IOPS and storage spaces
„Undo logs” based recovery points

6. Hyper-V Replica, Whats New ?
Online resize
Resize a running VM, no need to re-IR
Integrated with Hyper-V features such as VM migration & storage migration
Hyper-V Recovery Manager
Does *not* replicate virtual machines to Azure
Manage and orchestrate various DR workflows

7. Hyper-V Replica Broker
Configuration Benefits
Centralized management of the replication settings
Redirect traffic in case replica virtual machine migrates
Making the replica virtual machine, HA
Unified Configuration

8. Hyper-V Replica, Networking
Considerations
Data compression on by default
Work’s over low bandwith high latency link’s
Work’s over S2S VPN Gateways
Work’s over NAT’ed environments
Network scaling
Use Hyper-V Replica Capacity Planner
Use powershell to configure New-NetQosPolicy
QoS configurations for network throttling

Extended Replica - Powershell
IP Inject - Konzola
Storage QoS – dc2, Konzola – objasniti da replica QoS postavke ne ujteču na primary replica vm, te da je idealan slučaj za replice kod cloud providera
Network throttling – pokaži powershell
