Integrate Veeam Continuous Data Protection into your disaster recovery concept
With Veeam Backup & Replication, you can replicate VMware VMs every few seconds without vSphere snapshots. The feature is called Continuous Data Protection (CDP), which allows you to reduce RPO and RTO times for disaster recovery. CDP is based on the vSphere APIs for I/O Filtering (VAIO) and can be used very similarly to classic Veeam replication (which is snapshot-based). CDP can be used within your own data center or to a Veeam Cloud & Service Provider (VCSP).
When planning CDP, there are a few things you need to consider. As always, you need to allocate hardware resources for the data transfer and for storing changed data. While classic backups happen every eight, 12 or 24 hours, and only use network bandwidth a few times per day, CDP has a constant stream of data to transfer. Bandwidth estimations can be done by monitoring the storage write traffic. Veeam will apply compression and filter out unnecessary blocks (i.e., only transfer the latest version of a block that was changed multiple times within the RPO window). Because of this, the bandwidth required will be slightly lower than what you see on the storage.
