Lead Architect at a comms service provider with 1,001-5,000 employees
Centralized backups have simplified hybrid protection and improved ransomware recovery and compliance
The majorly needed improvement is that the product should easily simplify the upgrade and installation process. Sometimes Dell support should be more active. They take time for P1 issues. Sometimes it is not a P1 for Dell, but it is P1 for the customer, and the support needs to be very mature. That is a major drawback I see. Otherwise, the product is quite well. This is an enterprise solution and a bit costlier, but it is a solution where people should be looking into if they want to go into one single umbrella and have the centralized backup solution, which integrates with the cloud and can manage their cloud workload as well as the on-premises workload, and can be managed with one dashboard. In that way, it makes their backup management easier and they can get detected anomalies as soon as possible. This is one of the solutions I would recommend. However, if it is a very small company, they really need to think about the cost, as it is very costlier for them. But as an enterprise solution and a mid-enterprise solution, this is the solution where companies think their data is very critical, in sectors such as financial, banking, and health. This kind of sector should go with that solution because it always gives the compliances of HIPAA, GDPR, and all those things that are really required for them. From management perspectives and consolidation solution perspective, the integration is quite easy. With respect to the backup administrator and everything, it is quite straightforward. There are some layers that need to be improved and should have the internal feature instead of creating the additional VMs for the NAS backup. It should be internal and directly have the agent base or something that can communicate easily with Dell storage. If it is third-party, I would understand, but it should be able to communicate. The benefit of it is that it is easily understood and you can do knowledge transfer with a lot of documents available. The drawback of it is that when it comes to the installation, Dell always takes a lot of time for all these things with third-party involvement in between Dell and the customer. Support is the major part of it. People need to understand that when a customer raises their ticket for P1, they should treat it as a P1. Instead of by their book being P3 or P2, sometimes they only treat it as such when the complete backup server is down. However, for the customer, if it is not happening with the critical system of backup, then it is a P1 for them. From Dell support, they do not treat it as a P1, or they treat it as a P3 or P2. That kind of understanding and some agreements need to be done between the customer and Dell. It is a costlier solution. Comparatively, other backup solutions make this one of the costlier solutions. However, someone who has their enterprise data or needs protection in a good way can go for it. I could say it is a mid-enterprise or enterprise level solution. Otherwise, people do have the same solution but with differentiated features. However, it is costlier compared to the other.

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.
