The short-term restore points allow you to recover a VM to a state back to seconds or minutes ago (depending on the RPO that you specify) in case a disaster strikes. Because CDP is always on and does not create snapshots, it allows reaching a lower recovery point objective (RPO) compared to the snapshot-based replication - near-zero RPO which means almost no data loss.ĭata of I/O operations is stored on the target datastore and relates to short-term restore points. To read and process I/O operations in transit between the protected VMs and their underlying datastore, CDP uses vSphere APIs for I/O filtering (VAIO) that gives an option not to create snapshots. CDP also provides minimum recovery time objective (RTO) in case a disaster strikes because CDP replicas are in a ready-to-start state.įirst, CDP creates replicas and, then, keeps these replicas up to date.ĬDP constantly replicates I/O operations performed on VMs.
Continuous data protection (CDP) is a technology that helps you protect mission-critical VMware virtual machines when data loss for seconds or minutes is unacceptable.
