NW
HPE Product Manager at a tech services company with 51-200 employees
Collaborate effectively with partners and benefit from robust data management capabilities
The functions of HPE StoreOnce that I find most valuable are its deduplication and replication options. These features save data and reduce the size of data significantly. If the actual size for backup data is 100 terabytes, using StoreOnce, it will be around less than 10% of the original size due to the 1 to 10 deduplication ratio. So, compression and replication are critical features I appreciate. Additionally, adaptive backup and restore capabilities of HPE StoreOnce are indeed very helpful functions. As I know from my technical team, the process is very easy for end users because the GUI and user experience with StoreOnce are straightforward. They can restore their backups at any time. An important feature of StoreOnce is that they can reserve an amount of storage capacity as protected capacity for a limited time, safeguarding their data against intrusion and other interactions. Based on feedback from customers, StoreOnce is regarded as a highly useful solution for backup. I am satisfied with the security aspects of HPE StoreOnce, but it's crucial for any company to maintain a multi-layer security approach. Starting with a firewall is essential for maintaining their environment. Additionally, security features on StoreOnce are useful. I believe that no company should rely solely on one layer of security; they should adopt a multi-layer security strategy that begins at the network level and extends to their internal solutions.

Provides a short-term backup, archive, and cataloging for 20,000 people in our organization
The backup for a large amount of data is slow. When there's a large amount of data, sometimes the backup isn't completed in time. I have a 24 hour cycle, so it doesn't get completed in 24 hours with the large amount of data. With Veritas NetBackup, I can take 20 terabytes of backup in a day.

Quotes from Members

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

Pros

"It's cost effective, technologically advanced, and very scalable."
"It provided us help at a time when we needed a lot of storage quickly."
"The solution's most valuable feature is its catalyst mode, along with better performance, backup, and recovery."
"Deduplication and compression are in a good ratio. It supports the HPE Catalyst protocol, which is much faster than NFS and other protocols. We use CommVault and Veeam, and these two solutions support the Catalyst protocol very well and are integrated at high speed. It is faster than normal access."
"The most valuable feature of the solution is that the tool provides good value for somebody who needs an affordable and reliable storage solution."
"The initial setup process is simple."
"The initial setup is one of the most user-friendly B2B user solutions. It's good, it's easy. Deployment usually takes less than one day. You only need one person for deployment and maintenance."
"The deduplication feature in this product is amazing."
"The most valuable features are the self-service features and the ability to search the data."
"The solution is highly stable."
"In terms of stability, I've found it to be very stable."
"The most valuable feature is the incremental backup."
"I will highly recommend this product for excellent and quick backup solution in small and large IBM I Series environment."
"In terms of stability, I've found it to be very stable. I've walked into the server room when it was at 60 degrees Celcius, and it was still running fine."
"The cataloging is the best feature, as it takes millions of frames for the backup and, because it's incremental, it takes less time to complete."
"The command-line interface is good."
 

Cons

"We wanted to restore the files we backed up, and on three occasions we were not able to, and this got us in a lot of trouble, so I don't think I will take this risk again. Use something else."
"HPE StoreOnce needs to provide a SaaS solution by offering high-density disks."
"In terms of areas for improvement, I believe HPE StoreOnce could learn from competitors like Dell's Data Domain and ExtraHop in refining its architecture."
"One of the drawbacks of this product is that you cannot add another disk array when you reach capacity."
"The product's support is an area with certain shortcomings requiring improvements. Support needs to be faster."
"The user interface of HPE StoreOnce should be more user-friendly. Additionally, the configuration and troubleshooting could be better."
"Scalability can become an issue once you grow past the capacity of a single cluster pair."
"This product would be improved with the inclusion of more features to security or WORM."
"I would like the possibility to back up the infrastructure and then replicate it upon on restart, without having to orchestrate the starting of the VM."
"These days, we are thinking about pushing another solution because of the poor support from IBM."
"It is unmanageable. Support would be good."
"Setting up the system to work with legacy equipment is a bit complex at times."
"IBM ProtectTIER could improve by being more user-friendly."
"The configuration wizards are still complex and hard to navigate. These should be easier to manage."
"My advice to anybody who is considering this solution is to conduct a proof of concept first because everybody's needs are different, and this product is not suitable for every kind of backup."
"The backup for a large amount of data is slow. When there's a large amount of data, sometimes the backup isn't completed in time."
 

Pricing and Cost Advice

"The solution is pretty expensive."
"To be honest, we were quite happy with the price, but we always want things cheaper than they are. I think for what we got, we felt that the price was quite reasonable comparing it to other products that provide that same level of functionality."
"I would rate it around two or three because, compared to others, it tends to be higher priced."
"The price puts me off. It's definitely on the high side."
"I rate the product's pricing a seven out of ten."
"The product is not expensive. It is available at a good price."
"The licensing costs is capacity-based and come bundled with support."
"I rate the platform's pricing a seven out of ten."
"This solution is very expensive."
"We have a capacity-based license, which is managed centrally for all the sites of my company."
"IBM ProtectTIER is an expensive solution."
"The customer can decide how they want to purchase a license. However, the price of the solution is expensive."
