Backup coverage has supported immutable protection and now needs a more modern, intuitive interface
IBM Storage Protect is from a previous generation of backup software. In those days, backup software was complex in setting up and complex to manage. The new software, such as Rubrik, is very easy to use and more relatable to younger engineers because its interface design is more similar to Office 365 and the newer controls and labels that we are accustomed to. The difficulty that we now have with IBM Storage Protect is that for this day and age, compared to other products that are out there, it seems complex. If we look back 15 years ago, all enterprise class backup software was complex, so IBM was not any different. However, many of these older systems, such as Commvault, still have the same complaint that they are very complex because they have tried to keep that same interface and the same way it works. This suits them, but it probably needed a complete overhaul to bring it into the ease of use that we have with modern software. However, that upgrade has not been done. IBM Storage Protect has not been upgraded into a modern platform. It still looks a legacy platform.

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

"TSM provides ease of use for customers to recover from any type of data disaster."
"Incremental forever: This feature helps us reduce backup time and backup storage space."
"IBM Spectrum Protect has improved my organization with its total support of IBM products."
"Nothing beats this solution for file backup."
"We can freeze and start databases for consistent backups."
"It covers all the different operating systems. If you need backup, it can pretty much do everything."
"The fact that we can take the backup straight onto tape is the most valuable feature."
"Support of the IBM X platform and the backup data replication to DR are the most valuable features."
"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."
 

Cons

"The solution is quite outdated compared with others and I feel IBM to be lagging a step or two behind other vendors."
"I would like to see integration with Copy Data Management, which is an IBM product. Right now, these two products are siloed, so if these two become integrated, the product would become a bit of a powerhouse."
"I would like to see better cloud integration."
"Ease of use. That has got to be the one thing that I routinely hear from clients and customers, that it's a little bit more difficult than it should be. What I'm finding is that IBM has heard that and they're responding with updated interfaces and things like that."
"There could be various client systems and process integration included in the product."
"The licensing isn't very clear. They should work to simply or clarify the cost structure."
"The solution is evolving, so it has to be evolved to fit all new types of software requirements too."
"I think Spectrum Protect's interface is not so user-friendly, but the interface is not so friendly. Some of the functions are too complicated. I prefer a simpler solution."
"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

"That's no longer my department, but I have some past experience with licensing. It is not cheap. I would rate it a three out of five in terms of licensing. In terms of additional costs, there is management overhead. It is a complex solution and a lot of work goes into managing clients. It has gotten better over the years, but compared to its competitor, it is still heavy on management overhead."
"We chose IBM Spectrum Protect, because they actually have something called MSP pricing, which means managed services provider pricing. The pricing was attractive, and it seems to be a platform that IBM is totally investing on in terms of new functions and new capabilities."
"It is expensive."
"Its licensing is complex, and its price is not really reasonable. It is on the expensive side. IBM, in general, is slightly expensive, but with IBM Spectrum for the virtual environment, they are looking into the aspect of helping customers with the cost and providing a cost-effective solution."
"It is very scalable, but the downside is that it costs money."
"We worked our licensing into a capacity model, which is nice. Now, everything is much simpler to manage from a licensing perspective."
"The most important feature which I wish to be added involves the GUI, the user interface."
"Licensing IBM Spectrum Protect can be somewhat confusing for new users due to the options available, such as licensing on a capacity or per server basis."
"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."
