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."
"I like the fact that you can recover the VMs inside the appliance. For example, they're basically running this appliance on a Linux-based distribution, and they're spinning off KVM virtual machines inside."
"The predictive analytics are great and the reporting is awesome."
"It's not easy to scale it."
"Stability-wise, I rate this solution a nine out of ten."
"The ability to backup both physical and virtual machines, along with having an appliance store the backups locally instead of on a file server, NAS, or SAN."
"Iinstant recovery (allows a spin-up of your image as a VM on the appliance)."
"The backup feature and recovery option are good because they allow the instant recovery of Hyper-V nodes and files."
"Replication to Forever Cloud."
 

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."
"Support is great for small simple issues, but anything more difficult, it is hard to get good resolutions without having to badger them and their management."
"It would be great to have the job throttle/limit the max number of backups on a single ESXi host."
"Comparing the features and the working pattern, definitely they have to come down on pricing if they want to compete in the market."
"The ability to run just differentials without pulling the full on your archive."
"The solution’s support and onboarding process needs to be improved."
"No appliance update notifications."
"Network-based storage stability could be improved."
"Techs don't see to be well-versed in troubleshooting issues that arise and tickets stay opened for weeks for resolution."
 

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."
"Make sure you do the homework to size the solution properly. Buy the Enterprise Plus licensing if you can afford it."
"With respect to cost, my advice is to get what you need."
"Talk with the sales guys. They can work with you on the best package."
"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."
"Initial pricing is competitive. Renewal pricing is steep, so make sure to project costs for the lifetime of the appliance(s)."
"We found that the cost of Unitrends was about the same as the Dell DR6300. We liked the fact that the Unitrends appliance was all-in-one."
"I would rate the solution's pricing a four out of ten. The licensing is yearly and it depends on the customers."
"Their licensing depended on the number of CPUs you had."
