Question

Hyper-V VM backups directly to Dell Data Domain using Storage Accelerator

Hi everyone,


We are exploring the possibility of backing up Hyper-V VMs directly to Dell Data Domain using DD Boost, without routing the backup data through a MediaAgent.

The official documentation states that "Storage Accelerator is supported. You need to install Storage Accelerator and Storage Accelerator Add-on package on the clients." https://documentation.commvault.com/11.46/software/accelerating_backups_to_data_domain_boost_client_library.html
 

However, it is unclear whether this functionality is supported for Hyper-V backups at the hypervisor level.

Can anyone confirm whether Storage Accelerator supports client-direct backups of Hyper-V VMs to Dell Data Domain using DD Boost in Commvault 11.44? Are there any specific prerequisites or limitations?


Thanks in advance for your help!

Hi ​@Nikos.Kyrm , Storage Accelerator is supported with VSA yes, including Hyper-V, it’s not crystal clear on the docs yes, but it’s supported,

The Storage Accelerator and Storage Accelerator Add-on package can be installed on 64-bit Windows and Linux clients. (All the agents supported on Windows and Linux clients are supported.)

Accelerating Backups to Data Domain Boost Client Library

A media agent still needs to be on the library for DDB/Indexing just as any Storage Accelerator (SA) setup.

Thanks,

Abdu

    Hi ​@AbdulRahman AlSindiony 

    Thanks for the clarification!

    Just to confirm, with Storage Accelerator enabled for Hyper-V VSA backups, the backup data is transferred directly from the Hyper-V nodes to the Data Domain, meaning that the backup processing and associated workload are handled by the Hyper-V nodes rather than the MediaAgent. Is that correct?

    Thanks again!
