Multi-Stream support for Vmware Full VM Restore

Does Commvault support or plan to add support for Multi-Streaming during Full VM Restore in VMware?

For example, a VM with 4 ‘vmdk’ files can use 4 streams during restoration.

We are running ver 11.24 and see that a single stream is used during the restore which slows restores down, especially for larger VMs.

We could of course use Live VM recovery but that does not help if the VM is running any resource-heavy app.

Hi @Ameya Bapat ,

This was enabled in FR25 / FR26. So it is enabled in FR28.

Hi,

With async writes during restore, a single VMDK can have multiple outstanding IO requests. With this Full VM restores from FR25/FR26 will be faster.

Hello,

 

is this somewhere described? I am running FR28 and while restoring 1 VM with 10 vmdks I can see only one stream utilized.

Hi @Maciek ,

We are still using 1 stream / VM, however as Gopinath said, with async writes during restore, a single VMDK can have multiple outstanding IO requests. With this Full VM restores from FR25/FR26 will be faster.

Best Regards,

Sebastien
