Easy, Fast Recovery

Unitrends Bridge &  Instant REcovery 


As data sizes continue to increase, the amount of time you can be down has continued to decrease. Your RTO SLAs (Recovery Time Objective Service Level Agreements) can no longer wait for data transfer—you need to be able to gain the benefit of highly-available clustered systems at a fraction of the complexity and cost.

Enter Unitrends. Unitrends Bridge is a 1-click P2V (Physical to Virtual) capability that enables protected Windows systems to be transformed into virtual machines. It is also the technology that powers all of our Windows and virtualization-based instant recovery capabilities. With Unitrends Bridge, you’re able to:

  • Perform Windows Instant Recovery on our Recovery-Series physical appliances and our Unitrends Enterprise Backup virtual appliances.
  • Windows Instant Recovery operates at the GOS (Guest Operating System) level and physical server level.  For our physical appliances, Windows is transformed into a native virtual machine that operates on our appliance, or can be run on a Hypervisor as a VM registered as a client to the physical appliance. For our virtual appliances, the VM operates in essence as a standby server—constantly being updated by each subsequent backup.
  • Optionally relinquish control on a Hypervisor VM so that this VM no longer operates as a standby server. At that point you’re able to run, mount, shrink, grow, convert to other types, and perform other operations on the VM. You may also then protect it again.
  • Perform HOS-level VMware vSphere Instant Recovery and Microsoft Hyper-V Instant Recovery on our Recovery-Series physical appliances and our Unitrends Enterprise Backup virtual appliance.
  • Perform VMware vSphere Instant Recovery on our Unitrends Virtual Backup virtual appliance

Virtualization Failover

       A more recent advance in data protection is virtualization failover, which is more often termed by a derivation of the term “instant recovery.” There are two forms of virtualization failover: on-host and off-host virtualization failover. In on-host virtualization failover, a backup is executed as a virtual machine entirely using the resources associated with the server and storage upon which the backup software executes. Off-host virtualization failover is similar except the backup is executed as a virtual machine using primarily the resources of a second server (not the server upon which the backup software executes.)

Most vendors support off-host virtualization failover; fewer vendors support on-host virtualization failover –Unitrends is the only company currently supporting both. In addition, Unitrends and several other vendors support not just recovery but the “auditing” of machines using virtualization failover that automatically  boots backups in virtual machines to test the integrity of the data protection process. Virtualization failover, particularly on-host virtualization failover, adds even more complexity to backup software. Like deduplication, this has driven the desire for backup appliances since the task of balancing server, storage, I/O, and networking performance with virtualization failover is the backup appliance vendor’s responsibility rather than the buyer’s responsibility.
