Based on additional discovery, it was determined that a few critical workloads need to maintain...

•Veeam CDP is a technology that helps you protect mission-critical VMware virtual machines when data loss for seconds or minutes is unacceptable12.

•Veeam CDP leverages vSphere APIs for I/O filtering (VAIO) to constantly replicate I/O operations performed on VMs without creating snapshots12.

•Veeam CDP allows you to configure the RPO per second and achieve near-zero RPO, which means almost no data loss12.

•Veeam CDP also provides minimum recovery time objective (RTO) in case of a disaster, as CDP replicas are in a ready-to-start state1.

Veeam image-based replication is not the best option, as it relies on snapshots and has a higher RPO than CDP3. Custom PowerShell scripting is not a reliable or scalable solution, as it requires manual coding and maintenance. Veeam Backup Copy with immediate mode is not suitable for replication, as it is designed for copying backup files, not VM replicas4.
