Hi Team,

Customer has asked me about Azure Stack HCI backup recommended volume size. He sent me a link to MS docs


Customer is concerned about planning for volume sizes of VMs i.e. 2x10TB vs 1x20TB vm disk.

So the question that remains is: does Commvault use Hyper-V RCT API and/or ReFS block cloning?

Can I advice customer to go over 10TB vm disk without hurting performance?

@Robert Horowski , I heard back from dev directly.  Azure Stack HCI will use the Resilent Change Tracking API, the customer can use greater than 10 TB.

Let me know if this answers your question!
