Technical Lead at Cognizant

Support and connection issues affect user experience

I currently work at TCS in a different domain using AWS and Azure cloud backup. I switched from Cognizant to TCS four months ago, where I previously used Cohesity Data Cloud and Cohesity tools. I prefer Cohesity Data Cloud over AWS. While cloud functionality is similar across platforms, Cohesity Data Cloud's console, options, and web console are superior to AWS. The pricing of Cohesity Data Cloud depends on the data volume and retention period. Compared to alternatives, Cohesity Data Cloud is somewhat expensive. Regarding technical aspects, connection issues need to be addressed promptly. I would rate it eight out of ten, as these issues require immediate resolution to meet client requirements. Overall review rating: 9/10.

Expert Backup at a tech services company with 201-500 employees

A virtual deduplication backup appliance that protects physical and virtual data across remote sites, the datacenter and cloud deployments

Given its ease of use and management, I believe there are no specific caveats that users need to be aware of during the setup of DXRIS for backups. The process was straightforward, and I did not encounter any challenges or issues. As for a rating on a scale of one to ten, with one being the worst and ten being the best, I would rate the Quantum DXI Series a nine. My deduction is primarily influenced by personal preferences, particularly regarding the user interface and it is a highly commendable system, I would rate it a solid nine out of ten.

Quotes from Members

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

Pros

"We use Cohesity Helios primarily in our data management strategy for backup and reporting."

"It's very regimented and fast. It does local backup, cloud backup, long-term coverage, and disaster recovery."

"Our data center size occupancy for Cohesity appliance is reduced by 70% when we installed Cohesity."

"I definitely recommend this tool to others due to its simplicity, security, features, and flexibility."

"Cohesity Data Cloud is user-friendly, and anyone can use this tool; the support is really good, especially the web support, and the dashboard and everything are good."

"The clone feature is very nice. You can restore workloads onto Cohesity's storage, which is also nice to have when you don't have enough space to restore on the server."

"It is easy to install and use."

"It has excellent integration for virtualization, which means we can easily protect VMs, virtual machines, which consists mainly of snapshot backups that are quite easy to recover."

More Cohesity Data Cloud pros

"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 am impressed with the tool's technical alliance with Veeam and Veritas."

Cons

"There is limited support for legacy systems, which is something that could be improved."

"The only concern I have with cloud implementation is that if you have a presence on-premises, trying to use the cloud may become a performance challenge."

"They still have quite some way to go for improving their agents."

"The pricing of the Cloud is on the higher side, and it should be cost-effective enough to compete with native solutions."

"Sometimes the support team does not provide proper assistance during critical issues from the cloud end."

"In terms of functionality, Helios has been effective, but sometimes it doesn't show the exact cluster name for backups."

"The downside of Cohesity Data Cloud is that it is not supporting a legacy environment."

"The primary drawback is the need to transfer large amounts of data to the cloud via an internet connection, requiring significant bandwidth."

More Cohesity Data Cloud cons

"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."

"The product needs to improve performance while scaling out. It also needs to improve stability."

Pricing and Cost Advice

"It's priced properly for the market."

"Regarding pricing, it's very costly and I rate it a four."

"Competing products sometimes use deceptive marketing to make their products seem a lot cheaper. Comparing apples-to-apples, DataPlatform wins out."

"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."
