Has provided straightforward backup and rapid deployment for diverse environments

There is reporting in IBM Spectrum Protect Plus, but I'm not very familiar with this area. I always concentrated on getting the customer to do the backup, restore, and related tasks, but there is reporting. IBM has made a decision to withdraw the product and replace it with IBM Data Protect. The correct direction is Data Protect, which includes ransomware detection. With IBM Data Protect, you can add more servers for backup. It's scalable, which is a key feature over Storage Protect and Storage Protect Plus, even more capable than Veritas, because Veritas has an option to make different media servers. You can scale the backup process regardless of the load of the customer. This speeds up the backup and restore process for a complete data center, which cannot be done with any other product. I rate IBM Spectrum Protect Plus 9 out of 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

"Virtual snapshots that offer incremental backups."

"The tool has enough documentation; you don't need to contact the support team."

"Large-scale recoveries are very straightforward."

"The API is very good."

"The solution is scalable."

"The most valuable features of IBM Spectrum Protect Plus are you have many possibilities on how to use it. We use it for backups and to create secondary and third copies. It is possible to pick up Kubernetes containers and use a different cloud provider if you need to start backups on the cloud."

"The most valuable feature of this solution is the integration with Oracle."

"The solution offers a very straightforward deployment. You click, click, click and it's done. There's not much configuration to do."

More IBM Spectrum Protect Plus 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

"Their first level of support can be improved. Often they are too junior to understand the issues we are having, and it takes too much time to get from them to the next level of support, which is what we actually need."

"It requires much more automation features."

"IBM Spectrum Protect Plus could improve by adding SAP Rena."

"An area that needs improvement is data validation. We currently use another product that gives us immediate validation, information about when the last backup was, and no risk of corruption happening. TSM in IBM Spectrum is not mature so that you can validate on the spot."

"I think the graphical reports are a shortcoming of the tool since it fails to provide my company with what we want in terms of reporting. Due to the product's inability to take care of its reporting part, we have to use third-party software."

"The backup support for IBM Power Virtualization needs to be added."

"The solution only supports HyperV and VMware but doesn't support Nutanix."

"I would like to see continuous data protection (CDP). If there is machine failure, you don't have to go to the backup copy that you took 12 hours ago. You can actually go back to the backup copy made half an hour ago. That is, it would be good to have certain-point-in-time recovery."

More IBM Spectrum Protect Plus cons

"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 have a perpetual license for the tool since it is deployed on-premise."

"The solution is too expensive."

"In addition to the standard licensing fees, we paid for implementation and training."

"If you need to extend it, it can be extended acting like a normal Spectrum Protect with a long archive."

"There are a few options available for purchasing the solutions. Overall, the price of the is high."

"The price is perpetual, but the maintenance cost is annual. That is, we pay once for the product and pay annually for the maintenance and support. The price was much cheaper than what we would have had to pay for EMC or Veritas. The pricing is competitive, and I would rate it at four out of five."

"I rate the price of IBM Spectrum Protect Plus a one on a scale of one to ten, where one is extremely expensive, and ten is very cheap."

"The licensing model of Spectrum Protect Plus is more efficient and cheaper compared to the original."

More IBM Spectrum Protect Plus pricing and cost advice

"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."
