Interim Head of Infrastructure at a real estate/law firm with 1,001-5,000 employees
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

"Because of the flexible parameters, everything can be fine-tuned to the customers’ needs in their environment."
"Once setup, you do not need to touch it again. You just need to do a formal check on possibly batch updates."
"The feature that I have found the most valuable is that IBM Spectrum Protect is highly integrated with IBM ESS. In addition, it allows us to back up our virtual servers directly to take VM snapshots. It runs on Linux as well."
"It is perhaps one of the best products on the market, and it does a good job."
"I know Networker, Avamar, BackupExec but I like mostly TSM."
"It is an IBM product. With SAP, you are using IBM software to protect it. DB2 and AIX servers are both IBM. Therefore, it is a total IBM solution, which helps."
"The scalability of IBM Spectrum Protect is good."
"We optimize our costs of media and storage use, thanks to the Incremental Forever backup. The TDP software provides us many ways to protect our data, so we don't need to use monstrous scripts for doing backups now."
"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

"There is room for improvement in IBM Spectrum Protect, especially regarding its support for virtual environment backups."
"The software is very complicated. You have to do a lot of configurations to build a server, and you would need to backup and restore."
"A new adjustment to Azure cloud possibility to split big file spaces CIFS and NFS into smaller parts (together with storage split) in order to avoid retaking backup from scratch."
"We have run into some periods where we have found some tape issues which were causing us problems, but we resolved them. For some reason, we had a bunch of drives go offline on our disk storage (our virtual library)."
"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."
"Stability is very good now. It used to be rocky years ago."
"There have been some sizing issues now, and we are dealing with those."
"I have used similar products by several different vendors and I feel that many of them are better than IBM Spectrum Protect."
"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

"One can go with either a PVU licensing model or a capacity based licensing model. Either solution does not block the usage, if over used."
"The licensing is varied. If we have small environments (not many TB being managed) it is best to license by PVUs (depending on the number of cores of the machine). If we manage many TBs we look at licensing by capacity which allows us to use all the agents of the product."
"Spectrum Protect is not a cheap option."
"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."
"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."
"It is really expensive. Its price is not good for Latin America. Its price is good for the United States or Europe."
"I rate the pricing a four on a scale of one to ten, where one is not cost-effective, and ten is cost-effective."
"That's a hard estimate. It depends on the licensing, the hardware, and other stuff, but it is fairly expensive. It is generally more expensive than other solutions."
"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."
