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.

Backup storage has shrunk dramatically with deduplication but still needs stronger security options
The air gap feature is something I'd really like to see in QoreStor. There's no native air gap capability right now, and for security-conscious environments, that's a gap. The configuration export is also limited in QoreStor. If you want to document your setup or migrate configuration to a new instance, it requires more manual work than it should.

Quotes from Members

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

Pros

"We also really benefit from the GUI capabilities."
"The initial setup is simple."
"Catalyst backup is used to back up Oracle databases, and provides very good throughput during backups."
"The solution is stable."
"Backups are much quicker now; previously, it took 15-16 hours every day, and now it takes 3-4 hours maximum."
"The ease of use is excellent and the price point is very competitive."
"We can backup our exchange server, we can backup our files, and it just works without being overly complex either."
"After we implemented Catalyst with Data Protector, the recovery process time of one or two days was reduced to 30 minutes in most cases."
"The features we use for the data deduplication are nice because we're able to back up a much larger amount of data, yet it doesn't necessarily take up that much data on the devices."
"I would rate QoreStor a ten out of ten for what it offers for the price."
"Quest QoreStor definitely saved us money."
"The extreme compression of data is a big thing for us. We were looking for an online backup solution, and QoreStor is very good in terms of data compression. It helps us minimize the required storage in the Blob Storage environment."
"Overall, it simplifies the management of backup and gives me a more secure feeling that my data is going to be available if I need to retrieve it."
"Deduplication is the most valuable feature. It saves us a lot of space. When we back up 100 terabytes of data, after dedupe, it only uses maybe five to six terabytes for the disk space in QoreStor."
"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
 

Cons

"StoreOnce software is sometimes unstable."
"HPE StoreOnce needs to be made cheaper than products from Dell and Veeam."
"But the initial network setup is not intuitive, and this could be improved."
"The auto load balancing between VTL Libraries has been not as efficient as it should have been."
"When it comes to upgrading, it always goes block-wise. One block is 48 TB raw capacity."
"Six months after purchasing StoreOnce, the database became corrupt and the unit had to be replaced."
"With the older firmware we did have problems with the B6200 crashing with kernel problems, though this has now been addressed with the firmware updates."
"The support team needs improvement."
"The importance of support is significant to me. I was working for a service provider, and all of our customers had a Quest or warning. Sometimes the support really underperforms."
"The air gap feature is something I'd really like to see in QoreStor."
"The setup of the software is definitely not the easiest thing in the world."
"They could improve on support a little bit. We have not had to engage their support much, but when we do have issues, it can take longer to get things resolved."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"The ransomware protection of QoreStor could use improvement."
"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something. So that when we don't do a backup, we want the QoreStor to stay offline. It would be a nice feature to have."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
 

Pricing and Cost Advice

"There are costs for additional storage and space."
"I rate the platform's pricing a seven out of ten."
"The solution's cost is above average."
"I would rate it around two or three because, compared to others, it tends to be higher priced."
"The product is not expensive. It is available at a good price."
"Price-wise, it comes with a high price tag when compared to other products."
"The licensing costs is capacity-based and come bundled with support."
"I rate the product's pricing a seven out of ten."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
"Quest QoreStor's pricing is affordable. We evaluated Veeam, a well-known company for backup solutions, but found their pricing to be quite high. Veeam's price was almost double. For us, Quest QoreStor is very affordable."
"The pricing is good. It is competitive for a managed services provider. I like the ability to pay by the terabyte, allowing for an incremental cost that we and our customers can afford, so the solution grows with the customer."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
