Your customer contacts you to validate their current data protection solution based on Commvault and HPE StoreOnce backup targets based on Catalyst.
Is this a best practice for Commvault environments?
solution:Increase the chunk size on the Media Agent to increase the throughput, especially for environments with sequential access media like tape devices.

Does this topology/implementation comply with the 3-2-1 rule of data protection?
Solution:An HPE MSA array creating local snapshots on the same array Backups are made with Veeam to a local HPE StoreOnce system using MAS shares Within Veeam a copy fob is active to a Veeam Cloud Connect repository target hosted at a public cloud provider

A customer contacts you for assistance with performance troubleshooting of their backup environment because over the last few days they notice increasing times for backup completion They see no apparent reason for this, since the data volume to be backed up did not change unusually compared to the previous days and weeks.
You also notice that the deduplication ratio, historically steady at about 20:1. is now gradually declining Is this a potential cause of the problem?
Solution:Ransomware is encrypting data, making the dairy incremental backups grow and lowering the deduplication ratio due to new content.

Is this a supported integration with StoreOnce Catalyst?
Solution: Microsoft SharePoint

Your customer wants to replace an aging tape library with a new data protection solution that improves their RTO/RPSs.

Solution:Veeam supports HPE StoreOnce VTL.
