## How does churn rate impact agentless replication?

Since agentless replication folds date, the chun pattern is more important that the churn rate. When a file is written again and again, the rate doesn’t have much impact. However, a pattern in which every other sector is written causes high churn in the next cycle. Since we minimize the amount of data we transfer, we allow the data to fold as much as possible before scheduling the next cycle.

For example, if a VM takes four hours for a delta cycle, the next cycle is scheduled in two hours, and not in the next hour. This is differs immediately after initial replication, where the first delta cycle is scheduled immediately.

There is some performance mpact on vCenter Server/ESXi hosts. Since agentless replication uses snapshots, it consumes IOPs on storage, and some IOPS storage bandwidth is needed. We don’t recommend using agentless replication if there are constraints on storage/IOPs in your environment.
