TwinStrata Inc. made significant enhancements to the data protection features of its TwinStrata CloudArray cloud storage controller over the past year.

The major addition was a Disaster Recovery as a Service (DRaaS) capability for applications running on VMware. The DRaaS feature allows on-demand backup and recovery for apps and data without requiring a colocation site. TwinStrata's CloudArray DRaaS can work with traditional backup software, or with vSphere Replication software to recover a live copy of application data.
Other DR features include the ability to conduct tests from live product data, and to populate the controller's cache with data from the cloud to reduce time in testing or recover from a disaster.
CloudArray is available as a physical or virtual controller (software only). It uses an on-premises cache to provide local storage performance, and then moves less frequently accessed data to a cloud provider. Other features in CloudArray include bandwidth throttling and snapshot scheduling; it supports iSCSI and network-attached storage, and more than 20 cloud storage providers, including Amazon Web Services, AT&T and Google Cloud Storage.
One judge called CloudArray's DR features a "clever use of a virtual cloud-integrated storage [or cloud gateway] to provide DRaaS. It enables bringing up both the storage and VMs in an infrastructure as a service [IaaS] or platform as a service [PaaS] vendor's site almost instantly."
