Virtual Appliances

Unitrends Enterprise Backup™ uses our patent-pending Simply Scalable™ technology to excel at the challenges of enterprise-class data protection. Designed from the ground up, this appliance protects heterogeneous environments-virtual, physical, and cloud.

Simplify your Backup.

Virtualization creates enormous opportunity by enabling an agile IT infrastructure while reducing capital costs. Unfortunately, most data protection vendors have offered only advanced features available as point products, or data protection solutions with only mediocre functionality but expensive licensing fees. What’s needed is heterogeneous, enterprise-class, scalable data protection with next-generation functionality that is just as affordable as a niche product.

Unitrends Enterprise Backup is our software-only solution, available as a virtual appliance for Microsoft Hyper-V and VMware vSphere. Our software delivers the same proven Unified Data Protection™ as our Recovery-Series hardware appliances. A powerful, all-inclusive virtual appliance that can protect your virtual and physical infrastructure, host- and guest-level, and extend that data protection to the cloud.

Features Inside Unitrends Enterprise Backup

Design IT around your customers instead of your backup. Heterogeneous? We support over 100 versions of servers, storage, operating systems, hypervisors, and applications including NAS, SAN, Windows, Linux, Mac OS X, AIX, Solaris, iSeries, SQL, Exchange, Oracle, VMware, Hyper-V, and many others. Optimal data protection for this many different environments has driven a unique data protection architecture that supports agent-based and agentless protection as well as file- and image-level protection.
Flexible recovery strategies. Instant spin-up recovery? Yes. Instant granular recovery? Yes. But we’re just getting started. Similar and dissimilar physical and virtual bare metal allow you to perform P2P, V2P, P2V, and V2V recovery.
Flexible data protection strategies. Of course we offer incremental forever with synthetics for VMware and Hyper-V (as well as some physical environments as well.) But we also offer fully customizable configurations of backup strategies including full/full, full/differential, full/ incremental, and completely “create it yourself” strategies as well. And we don’t limit you to single server job scheduling nor do we force you to use multiple server job scheduling - we offer both.
Global deduplication and CBT. We offer compression and deduplication across multiple storage devices via our advanced storage virtualization and thin provisioning capabilities that are built-in to our virtual appliances. And CBT (Change Block Tracking)
is supported on both Microsoft and VMware hypervisors to eliminate redundant data as well.
Instant recovery. Failover virtualization enables instant recovery for VMware
Near-continuous data protection. World class RPO (Recovery Point Objectives) - backups can be performed as often as once every 60 seconds.
Archiving: make the most of your WAN. Disk, tape (if the hypervisor supports it), NAS, and SAN rotational and fixed archiving of tertiary backups is built-in and works alone and with replication.
Replication and disaster recovery. Single-tenant and multi-tenant replication is supported both in a private cloud as well as our public cloud Unitrends Cloud service.
Environmentally adaptive user interface. Our technology supports scaling up and scaling out, but what about scaling down to lower the learning curve of less experienced users? Our environmentally adaptive user interface provides ease of use without sacrificing click minimization for experienced users. And unlike other products, all with virtually no wizards.
