Backup platform has significantly improved recovery speed and reliability for critical outages
Instant Virtualization is the best feature of Datto SIRIS that we have liked so far, as it allows us to boot servers in minutes during outages. The use of Datto SIRIS has significantly improved our Recovery Time Objectives. We have been using other software like Veeam and Microsoft Backup as well, so we have found Datto quite competitive to them. Our experience has been good so far, our clients are satisfied, and we have been handling outages effectively. We have not had the opportunity to use the One-Click Disaster Recovery feature because the last time we experienced a phishing attack, it was resolved and did not escalate to a disaster scenario, so we did not need to use that feature. Datto SIRIS improves reliability by providing storage space that enhances overall dependability. The centralized dashboards in the Hero Reports feature have been most beneficial for our IT reporting needs. The Hero Reports feature provides extensive capabilities that include the specific points we need for our demonstration. Even if we want to use these features to train machine learning models, they are very useful for us, and we do not need to perform much work on the data to extract those features. It has helped in reducing disaster recovery testing hours because it has features that help us by monitoring malicious activities throughout the database and notifying us of any fluctuations in normal behavior. Datto SIRIS is good at assessing effectiveness regarding ransomware recovery, and it is competitive in the market. However, the only concern we have been thinking about is its pricing. The pricing of Datto SIRIS is more expensive than Veeam and Microsoft Backup. On the other hand, it provides many more options and much greater feasibility.

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.
