New Unitrends release delivers up to 50 times faster backup windows

Published: Wednesday, 20 May 2015 08:31

Unitrends has announced the availability of Release 8.1, the latest version of the data protection software powering its Recovery-Series family of physical backup and disaster recovery appliances as well as its Unitrends Enterprise Backup (UEB) virtual appliance.

Release 8.1 provides customers with up to 50 times faster backup windows, a new Red Hat Enterprise Linux deployment option and advanced support for VMware vSphere 6.

Faster backup windows

Release 8.1 includes a new changed-block tracking feature for Microsoft Hyper-V environments. This new filter driver more optimally tracks changes to virtual machines at the hypervisor-level as they occur, resulting in up to 50 times faster incremental backup windows and much shorter recovery point objectives (RPOs).

Full support for VMware vSphere 6

The new release also extends VMware protection to support vSphere 6. In addition to hypervisor-based protection, Unitrends also enables the protection of applications and operating systems within one or more VMware vSphere virtual machine. With this feature, administrators can set different RPOs, recovery time objectives (RTOs) and service level agreements (SLAs) at the hypervisor level as well as granularly within the virtual machines themselves. They can also granularly control the amount of data to be protected rather than having to select the entire virtual machine.


Driven by market and customer demand, deployment options for UEB now include execution directly on RHEL in addition to packaged virtual appliances for VMware vSphere and Microsoft Hyper-V. The RHEL integration provides greater scalability for larger enterprises and includes direct attach for tape archiving.

Unitrends Free

Unitrends Release 8.1 is the engine behind the company’s newly released Unitrends Free software, a free virtual storage appliance aimed at IT professionals seeking cost-effective protection for home labs, early-stage virtualisation projects and small environments.
