Syed Habib - PeerSpot reviewer
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.
PascalSebat - PeerSpot reviewer
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 interface is easy to use."
"It has to ability to backup DV2, Oracle, and Informix."
"The most valuable feature of this solution is the centralized enterprise backup."
"The business value comes from the capability to overcome data losses."
"Scalability: Our customers are able to grow the product without having to buy additional hardware, so it is very scalable."
"Disk-based implementation of a data protection solution for multiple sites is a better fit for my complex data protection needs."
"It has a lot more capabilities and functions than a lot of other products. Even though it is more complex, the reason is because it gives you a lot more features. This is what I prefer, especially for a long retention."
"SPIR is Instant Recovery for Spectrum Protect. It sends snapshots using space efficiently and blocking backups to the Spectrum Protect server. It provisions the snapshot from the backup server to the same or new server near instantly."
"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

"I would love to see something which allows us to do an auto restart of backup jobs."
"No one can fix every solution for backup and restore."
"The licensing isn't very clear. They should work to simply or clarify the cost structure."
"If IBM could provide a partial module, that would be great."
"Integration with Windows environments needs improvement. It should be more "assisted", both at the application and database level. It remains a product that fits better in Unix/Linux environments than in Windows environments, given its configuration procedures."
"It does not do too well in our virtual environment."
"The previous GUI that they had was slow, and it did not have enough information on it."
"They need to do a better job on Windows, because if you are running Windows, the scalability is more limited than AIX and Linux."
"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."
 

Pricing and Cost Advice

"We worked our licensing into a capacity model, which is nice. Now, everything is much simpler to manage from a licensing perspective."
"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 solution has a capacity based licensing, front and back-end license."
"We pay for a terabyte license to support our backend usage."
"Customers need to pay for licensing in order to use IBM Spectrum Protect. The customers that have been using it for a long time are okay and happy with it. From a cost point of view, it's better for them to renew their licenses than to go through the difficult process of changing a backup product in their environment, and migrate from one product to another."
"I rate the pricing a four on a scale of one to ten, where one is not cost-effective, and ten is cost-effective."
"The licensing fees are between $8,000 and $10,000 per year."
"We worked our licensing into a capacity model, which is nice. Now, everything is much simpler to manage from a licensing perspective.​"
"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."
