VMware Replication has been around since 2012 and can be used independently or incorporated in VMware Site Recovery Manager (SRM) for disaster recovery strategies. The VMware vSphere Replication license is included in vSphere Enterprise Plus, while the SRM is a standalone product and license by VM or processor as part of the vCloud Suite Enterprise.
Designing and maintaining multiple virtual machines (VMs) at all levels of the computing stack is an essential element of any modern IT infrastructure. VMware virtual machines have to be protected and backed up despite all this. To protect your VMware environment efficiently and cost-effectively, you should consider VMware replication as a powerful backup tool.
Organizations across the globe can use this backup to achieve performance, availability, mobility, and, what is most important – security and never to lose critical VMware data. VMware vSphere backup is a must for any data recovery scenario since virtual machines need to be covered up with full data disaster recovery scenarios to avoid corrupted data to overload the vSphere replication implementation.
VMware Replication protects your VMware virtual environment by replicating your VMware environment in a secondary location. It also uses network-based replication; SRM uses string-based replication for storage or network-based vSphere replication.
What Is VMware Replication – Definition
VMware Replication is a feature of the vSphere platform. Copies a virtual machine to another location, in or between clusters, and makes that copy available for restoration through a VMware vCenter Server-based web-based user interface. It replicates the changes made to the virtual machine to the manuscript. vSphere Replication resumes adding an additional layer of protection to the virtual machine on an ongoing basis.
It will assure the user that the virtual machine remains protected and is available for recovery without restoring a backup. vSphere Replication is provided as a component free of charge for all eligible vSphere licenses, from the VMware vSphere Essentials Plus Kit to the VMware vSphere Enterprise Plus Edition.
In order to replicate virtual machines, you can use a proper replication configuration or a backup replication process (backup system) for virtual machines. vSphere replication appliance limitations cannot be neglected, since vSphere replication creates a host-based replication process to source virtual machine recovery point objective (RPO).
As with VMware data backups, virtual machine protection is a critical hypervisor platform data center. VMware Replication provides a familiar and acceptable screen for all aspects of virtual data center management, including many protections such as replication, backup, and recovery. Unified control of vSphere Replication is provided through the next generation VMware vSphere Web Client.
Replicas can be formed from both source VMs and existing VM backups to lower the load on the production atmosphere. Employing backups as a source and automating replication eliminates your production hardware and saves time.
VMware Replication backup retention
VMware Backups can maintain a generation or day retention value for Full or Differential Backup. Users will need to back up the same folder as their additional backup by scheduling or manually performing a full backup that includes a backup value to apply personal backup.
Setting up VMware Replication configuration
Step 1: Choose an individual virtual machine and click on the “Replication” button.
Step 2: After selecting the replication key, click “Next” to complete the replication task immediately.
Step 3: Next, you will schedule your replication work.
Here, users can choose to schedule replication work on various methods. Users can switch the layout in the upper right corner to turn off the scheduler if no format is desired.
Step 4: Click Finished, and you’re done.
How does VMware Replication work
VMware Workstation also includes virtual networking between your guest VM and the NIC (network interface card) on your device (PC, smartphone, laptop), which expires on the network.
When you move your device from one network to another, this feature ensures that the VM’s address is automatically restored and redirected to your VM. A sheer number of networks utilize DHCP (Dynamic Host Configuration Protocol) to assign your device with newly appointed local IP addresses automatically.
VSphere Replication Appliance is installed on the source and destination. It creates a copy of the virtual machine in the target utilizing VR agents by transmitting adjusted VM blocks between the original and the target. It also makes a VM-based host replication between different locations. This method emerges independently of the storage layer, other than how SRM works using array-based replication.
To create an initial virtual machine and copy it to the target, vSphere Replication fully synchronizes the original virtual machine and its replica. The amount of synchronization between the source and the target depends on the Return Point (RPO) Purpose and the Retention of Multipoint Samples (MPIT) to keep the selection in your replication settings.
All vSphere Replication configuration data is stored in a built-in database. You can also use an external database to implement vSphere Replication. By default, vSphere Replication can use three default scenarios:
- Replication between two locations
- Replication in a single vCenter server
- Replication of a common target location
VMware Replication benefits and features
VMware Replication removes prohibitive disaster recovery requirements due to its unique features such as:
1. It is agnostic for storage
VMware Replication is independent of storage technology, unlike most array-based replication techniques. It can work with any storage, including traditional storage network (SAN), network-attached storage (NAS), virtual storage area network (vSAN), and direct-attached storage (DAS).
2. Has a flexible point of recovery (RPO)
VMware Replication provides an RPO of between 15 minutes and 24 hours, which vSphere administrators can configure based on VMs. It is a practical tool that can aid organizations in managing the recovery process in just a few hours.
3. Replicates only changes
After the initial and complete replication of the VM to its destination, VR guarantees that only the changes are copied to the target virtual machine disks (VMDisks) using recordings that save the restore points.
4. There is a simple deployment of a virtual device
VR Appliance uses the open-source virtualization (OVF) file of the vSphere web client. There is no necessity to install or structure these components as they are already built into the vSphere platform, further simplifying VR deployment.
5. It supports Microsoft Volume Shadow Copy Service (VSS) and Linux File System Quiescing
VSS and the guest file standby system provide a consistent interface for seamless coordination between users and backup applications. It improves the reliability of the updated VMs.
VMware Replication offers clear benefits, but there are a couple of disadvantages:
- Bandwidth consumption
- Operating overhead
6. The usability of VMware Replication
vSphere Replication uses vSphere’s Changed Block Tracking (CBT) feature, copying only the changed blocks to recovery. Reduces bandwidth utilization and makes achieving lower recovery point (RPOs) goals easier than making a complete system copy of the VM.
vSphere Replication supports RPO from 15 minutes to 24 hours. Although built into vSphere, vSphere Replication requires a separate license. It consists of three components – vSphere Replication Server (VRMS), vSphere Replication Server (VRS), and vSphere Replication Agent (VRA).
VRMS and VRS are virtual devices. The replication management server vSphere allows the administrator to replicate replication across hosts centrally, while the vSphere replication server performs accurate data replication.
Enterprises can use VR to deliver flexible, reliable, and cost-effective replication solutions for data protection, disaster recovery, and data center migration. vSphere Replication facilitates virtual machine (VM) replication of the virtual layer instead of the storage layer, as required by previous versions of vSphere and SRM.

Policy-protected virtual machine protection is enabled because VMware Replication configuration is attached as a feature of the virtual machine itself.
