AhmedEl-Tayeb - PeerSpot reviewer
Sales Manager at a tech consulting company with 201-500 employees
Has offered a cost-effective option with solid results but requires automation features for better efficiency
For ExaGrid EX, I would appreciate additional features such as backup and restore, automation processes, and automation software for backup and restore processes. I mention that some additional features may be provided by VMware or Dell as support for the hardware they are selling, but ExaGrid EX is more of a budget-friendly solution for customers who are in charge on a daily basis of the solution itself, dealing with manual tasks rather than automated tasks. I am not in a situation to provide an exact answer for what I would specifically improve in this regard.

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.

Quotes from Members

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

Pros

"Backup and restore processes are much shorter now, and we don't need forklift upgrades every three to four years."
"Both the pricing and the performance are excellent."
"I find ExaGrid EX to be a useful solution for customers looking for a budget-friendly product."
"The most valuable features of ExaGrid EX are the Veeam features and Landing Zone."
"The most valuable feature would be the high deduplication ratios, capable of 20 or more to 1 dedup ratio in a real-world backup environment."
"The scalability is very good."
"The solution's licensing policy is more practical and not confusing."
"The Federated Catalyst Replication and the deduplication ratios obtained are amazing."
"Based on customer feedback, I rate it highly as one of the most stable products in the backup and archiving line compared to offerings like Data Domain or from Huawei and Lenovo."
"The product has really improved the backup and restore for our infrastructure."
"The most valuable feature of HPE StoreOnce is the virtual drive."
"Previously, if someone lost a file it could take 10 minutes to locate and load the appropriate tape, now the restore time is around five seconds."
 

Cons

"ExaGrid EX is more of a budget-friendly solution for customers who are in charge on a daily basis of the solution itself, dealing with manual tasks rather than automated tasks."
"I would like to see free disk space."
"The solution’s web access should be improved."
"HPE StoreOnce Backup to Disk (BTD) is not a good backup solution for NAS devices. It does not have a dual controller, so if one controller fails, the entire system will go down."
"This is an entry level model, even more disk space would be valuable."
"The appliance doesn't have the global deduplication, it has StoreOnce deduplication. It does not deduplicate across the appliance, it will deduplicate in one particular store. With the global deduplication, I could store more data."
"Six months after purchasing StoreOnce, the database became corrupt and the unit had to be replaced."
"Maybe when we do restores for Veeam, the way it has to re-hydrate all the deduplicated data, if there's a way to speed that up that would be a good feature, some kind of algorithm or something."
"We had one problem when data replication got stuck and we had to ask HP for help."
"The CIFS share service performance is really poor; it is a nightmare."
"We would like to see some improvements in the Veeam Backup & Replication integration. It's good, but it has a lot of room to improve. In particular around the inability to easily move data between StoreOnce appliances."
 

Pricing and Cost Advice

"The renewal fee is approximately $3,500 to $3.750 for a 60 terabyte device."
"I rate ExaGrid EX ten out of ten for pricing."
"Price-wise, it comes with a high price tag when compared to other products."
"The price puts me off. It's definitely on the high side."
"The licensing costs is capacity-based and come bundled with support."
"The cost of HPE StoreOnce is very expensive."
"The product is not expensive. It is available at a good price."
"With the same capacity of Data Domain and ExaGrid, which is 80 terabytes, HPE is the cheapest one."
"HPE StoreOnce is cheaper compared to other solutions in the market."
"I think the product is competitive in terms of pricing. Other products like the one from Dell are costlier compared to the tool."
