Manageable and comprehensive and integrates robust backup features for core banking
It's adequate for my core banking, however, I am looking for another solution for all systems. It is not compatible with other operating systems like Windows or Linux, and lacks a consolidated dashboard from Browser Spectrum. This is why I am searching for another solution. The product also lacks any centralized graphical user interface (GUI), such as Jarek Pod, and I am limited to using a console-based text user interface, which my local partner handles completely.

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…

Quotes from Members

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

Pros

"The solution is really scalable."
"It allows us to have one interface."
"In the past, one of the most valuable features, and the biggest advantage, was the incremental forever feature. Not many other backup vendors provided that. In the pre-virtualization environment, it was very robust and simple technology, especially writing to tape."
"The ability to do dedupe in the product is nice to have."
"It is a very mature product."
"The main feature of this product is a flexible architecture and functionality that allows you to solve problems of any complexity and scale. Most importantly, it is not just a product that simply makes a backup, but it restores and saves a large number of services in critical situations. By the way, it works fine with different types of clouds, supports S3."
"Regarding stability, it's been rock solid."
"It is more efficient than most traditional backup solutions."
"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

"It lacks reporting and an efficient alert mechanism. The GUI could also be improved."
"It is not compatible with other operating systems like Windows or Linux, and lacks a consolidated dashboard from Browser Spectrum."
"High availability (HA) is a scalability challenge."
"It can be improved for large file systems with many files. Spectrum Protect can restore large files very well, but if you're restoring millions of little files, it is not as great. At one point, we tried to implement the VMware module with it, and it was awful and terrible. I don't know if that has improved. If it hasn't, this would be one big improvement."
"They do not have a unified GUI, they only work on CLI and operations center, which is really complicated for the installation and configuration."
"The installation process could be simplified."
"Most customers still struggle with the reporting piece, especially generating reports. I think it needs some improvements in this area."
"Its management part can be better and simplified. It is kind of a beast as compared to Commvault or Veeam, but they are more user-friendly. They are also easier to learn, whereas Spectrum Protect definitely takes time. They should simplify it. Our teams are pretty comfortable with it because we have been using it for a long time, but from the perspective of a new user who is evaluating or using this solution, it is definitely more complex in terms of manageability. Its monitoring could be improved so that it can even monitor the jobs that are scheduled by external schedulers. There are situations where a database team might decide to use their own schedulers, but currently, Spectrum Protect is not able to catch those jobs in the Operation Manager console."
"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

"The license model that they have at IBM, which is due to volume, from a certain volume onward is not the right license model."
"The product is not cheap."
"IBM Spectrum Protect can be considered an averagely-priced product."
"IBM Spectrum Protect has a fixed price and includes no additional costs."
"The price of IBM Spectrum Protect is expensive and there is only a standard licensing fee."
"The pricing model of this solution is another difficult area, it's very sophisticated in the way they charge. It's based on PBU, which is a type of processor, how, many processors, and you need to put everything into an equation. However, they have different ways of charging or licensing. One way is a back-end volume or front-end volume, which is quite complicated."
"You need to put it in a PoC and test it out if you can."
"The solution's pricing is fair. Price-wise, I rate the solution an eight out of ten."
"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."
