Protecting VM workloads on VxRail clusters can be achieved with various options. Given the various requirements customers may have for their virtualized workloads, there are several data protection options to ensure the appropriate protection level is available. The figure below organizes different data protection options according to the service level objective that needs to be met, from continuously availability to archival.

Stretched clusters is a native vSAN software feature that allows customers to have site level protection with zero data loss and near instantaneous recovery. This setup has automated failover in case of site failures. For customers looking for disaster avoidance and zero recovery point objective (RPO), stretched clusters is the appropriate data protection option. As a native vSAN software feature, VxRail LCM features supports stretched cluster deployments. Refer to the VxRail Planning Guide vSAN Stretched Cluster for more details: https://www.dellemc.com/resources/en-us/asset/white-papers/products/converged-infrastructure/h15275-vxrail-planning-guide-virtual-san-stretched-cluster.pdf.
Dell EMC RecoverPoint for VMs (RP4VM) provides a flexible replication solution for virtual workloads running on VxRail clusters. It can provide synchronous replication between sites to mitigate site loss events. With its point-in-time and asynchronous, local replication capability, replicated copies or snapshots can be re-purposed for test/development, operational recovery, and short-term backup and long-term backup use cases. RP4VM is managed directly vCenter Server. It is storage agnostic so that VMs on VxRail clusters can be replicated to other storage options including cloud service providers for cloud disaster recovery solutions.
VMware vSphere Replication is a hypervisor-based, asynchronous replication for VMs. It is fully integrated with vCenter Server and the vSphere Web Client. vSphere Replication can provide local data protection and can be an appropriate disaster recovery solution between sites for environments that can tolerate some data loss. It can be combined with VMware Site Recovery Manager to deliver automated failover and failback to minimize downtime.
Local backup and recovery solutions include PowerProtect software and Data Domain Virtual Edition (VE), PowerProtect appliance or IDPA (Independent Data Protection Appliance) as backup repositories. The PowerProtect software provides comprehensive backup and point-in-time recovery. Data Domain VE can be deployed on a VxRail cluster for a consolidated environment. The PowerProtect appliance and IDPA are purpose-built data protection appliance designed as a backup target where capacity and balanced performance are priorities.
Cloud replication, backup, and archive options are also available with VxRail clusters. RP4VM can replicate VMs to VMware Multi-Cloud deployed on AWS for a hybrid cloud site recovery solution. RP4VM and PowerProtect can also replicate and copy backups to AWS S3 for more cost-efficient backup or archive solutions.
