A scalable solution with Veeam and Vertias alliance
I am impressed with the tool's technical alliance with Veeam and Veritas.  The product needs to improve performance while scaling out. It also needs to improve stability.  I have been using the product since seven years.  I would rate the product's stability a nine out of ten. I would rate the…
Todd Guthrie - PeerSpot reviewer
The solution can be used to back up servers and Hyper-V cluster nodes, but its support is super expensive
I wouldn't rate Unitrends a ten out of ten because we had some hard drive failures in the appliance. Typically, when you have OneDrive, you can get it replaced. For some particular reason, the situation caused the entire system to crash. We had to reinstall the CentOS operating system on it, and we lost all our backups. They said there was no way to retain it, and it was pretty devastating and concerning that a drive failure would cause the loss of all the data on the appliance. It was extremely disappointing, and we had to start from scratch after three years worth of backup data. I rate Unitrends a nine out of ten for stability.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I am impressed with the tool's technical alliance with Veeam and Veritas."
"While the challenges posed by the difficulties were significant, they prompted the replacement of problematic components, resulting in the resolution of issues. Importantly, there were no substantial ongoing concerns. Regarding the overall performance, it has been consistently excellent."
"Unitrends has helped us cut down the time that it takes to restore a server to its original configuration."
"The most valuable feature of Unitrends for me is the automated feedback"
"The predictive analytics are great and the reporting is awesome."
"I am impressed with the tool's reporting and UniView features."
"They have great support."
"If you are a large organization, this is a product for you."
"VM backup is much faster and more reliable, as I can test my backups with Data Copy Access jobs."
"I really like the reporting options you get for various email reports."
 

Cons

"The product needs to improve performance while scaling out. It also needs to improve stability."
"Perhaps the most notable area for enhancement lies in the web interface for management. The current limitations in LDAP editing capabilities are not addressed in the UI, and I haven't observed any recent updates. It's possible that the new version of the DXI service incorporates improvements in the GUI, but I cannot confirm. While there is room for improvement in the current GUI, it remains a relatively minor issue. Overall, the system is comprehensive, covering aspects such as reports on latency and networking, leaving little room for additional enhancements in those areas."
"Unitrends can be challenging to scale."
"Comparing the features and the working pattern, definitely they have to come down on pricing if they want to compete in the market."
"No appliance update notifications."
"Probably the biggest issue I've had is actually paying for the unit, and part of that problem is that they use a third party for the billing."
"I would like to see the real-time replication process improved, and a zero RPO feature added."
"​​Follow up for the DRaaS service setup. I'm still waiting to schedule a DRaaS test after upgrading several months ago."
"The solution’s support and onboarding process needs to be improved."
"There's a lot that can be made better. For example, it could be more scalable."
 

Pricing and Cost Advice

"I do not oversee this aspect, as pricing is contingent on factors such as volume, technical specifications, and the desired features. Consequently, I lack information on the pricing details and structure."
"When you purchase initially, get into the program which gives replacement hardware for free when you renew your support agreement."
"No comment."
"Initial pricing is competitive. Renewal pricing is steep, so make sure to project costs for the lifetime of the appliance(s)."
"Based on a scale of one to ten, with one being low and ten being high, I would rate the pricing of this solution as a three. Also, there are no additional costs involved in the standard licensing of the solution."
"The cost of Unitrends definitely draws you in. The licensing is all included in the appliance, which is a great incentive."
"You should be aware how much the monthly costs are to use, what the initial costs for hardware are, and what the options to expand are, if needed."
"Their licensing depended on the number of CPUs you had."
"I would rate the solution's pricing a four out of ten. The licensing is yearly and it depends on the customers."
