Valuable Features

HPE StoreOnce provides efficient data management through high-performance deduplication, scalability, and seamless integration for optimal backup and storage solutions.
Microsoft DPM efficiently manages VM migration, backup, and recovery, integrates with Microsoft tools, and supports SMB environments.
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.

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.

User finds setup straightforward but seeks wider platform support and advanced features
Microsoft DPM could implement backup capabilities for third-party systems such as Linux. They also need to consider other features such as replication to DR sites, similar to what Veeam and other products offer. Microsoft DPM didn't have that capability at that time. If they want to remain competitive in the market, they need to observe the competition and implement improvements. The backup should have compression, deduplication, and DR replication. They should also improve monitoring of the environment. Microsoft DPM didn't have these basics at that time. If they had continued development on the products, they could have reached a higher level, especially given Microsoft's significant presence and majority of servers. Microsoft DPM didn't have any support structure in the backend. If they had a support structure, we could have escalated issues. I never received any support from Microsoft DPM.
