We are delighted to announce that Azure Site Recovery Higher Churn support for Azure VMs is generally available now. In this support, Azure Site Recovery has increased its data churn limit by approximately 2.5x to 50 MB/s per disk. With this, you can configure disaster recovery (DR) for Azure VMs having data churn up to 100 MB/s. This helps you to enable DR for more IO intensive workloads.
This is an opt-in support. To opt for the higher churn limit is very easy – you need to select the option High Churn when enabling the replication. By default, Normal Churn option is selected. If you want to use the higher churn limit for Azure VMs already protected using ASR, you need to disable replication and re-enable replication with the High Churn option selected. Please note that this feature is only available for Azure-to-Azure scenarios.
