Disaster Recovery as a Service protects your business, as opposed to only the data. This allows your to recover your entire IT environment – servers, storage, network, data, and apps – in the cloud. You can quickly resume business operations in a matter of hours, instead of waiting until their onsite environment is rebuilt. Disaster Recovery typically leverages replication technologies, which can be host-based (at the server level), like Double-Take or Zerto, or array-based (at the storage level), like EMC or NetApp replication.
