Competitive – Unitrends Versus Zerto

Why Unitrends?

Our mission – the reason Unitrends exists – is to increase your uptime and confidence in a world where you must do more with less.  We don’t sell you a piece of backup software and tell you to slap it on Windows and figure it all out yourself; we sell cloud-empowered, purpose built, all-in-one backup appliances (hardware and software) that operate on your premise and in AWS and Azure.

Why Unitrends?  Because we’re customer obsessed – one vendor, one throat to choke, and a whole lot more that you can read for yourself below.


Unitrends Versus Zerto

Zerto is not a backup solution, but a replication solution for Disaster Recovery. Zerto drives its marketing around short Recovery Point Objectives (RPOs) due to its unique replication methodology. However, achieving RPOs of seconds – as Zerto claims – are rarely achieved given environmental limitations. Additionally, Zerto’s architecture leaves customers paying more and adding risk to their continuity strategy.


Top 5 Reasons to Choose Unitrends Over Zerto


Simple Deployment

  • Zerto requires a virtual appliance per host – high complexity. Zerto requires an intrusive installation into the vSphere kernel – high risk to production apps and VMware support
  • Zerto requires a Windows machine in the cloud – more management cost and ransomware risk


Lower Cloud Costs

  • Zerto requires an m4.x Large Windows VM to run in the cloud for replication, adding over $4300 per year to your cloud cost
  • Unitrends Boomerang leverages “Pilot Light” technology that uses no cloud compute until you need to failover


1-Step Failback

  • Zerto has no failback process. You get to the cloud and cannot come back without using painful 3rd party tools
  • Unitrends Boomerang can return a running machine in the cloud to the on-premises VMware environment in a single-step


1-Step Restore

  • Zerto only provides granular recovery from cloud storage
  • Unitrends Boomerang brings full VMs back from cloud storage in a single-step, giving confidence that you are not held captive in the cloud


100% Confidence with Recovery Assurance

  • Unitrends Cloud offers true SLAs, which cannot be achieved using shared, hyperscale infrastructure like AWS and Azure. Unitrends Cloud with Unitrends Backup software and Recovery Series provide the great alternative.
  • Zerto uses its own (unsupported by VMware) IO filter that leaves all machines in a crash-consistent state (Blue Screen Risk!) They also don’t offer enterprise-level capabilities such as seeding and white glove service for DR. They also have no physical support.
