I'm hoping someone might be able to clarify that what I'm doing is intended to work.
My environment is fully Hyper-V, and all backups are done using the Hyper-V agent, protecting VMs.
I have a 300GB dataset in a VM in Branch Office #1. It's currently protected by a Datto residing in HeadOffice. The Commvault Media Agent involved also resides in HeadOffice.
I have restored the 300GB dataset from the Datto to a VM in the HeadOffice. This VM is then Full backed up with a storage policy using a Global Dedupe policy.
Next I set up a subclient for Branch Office #1 VM, using the exact same storage policy selection. A Full backup is performed, and I expected this to be a fast operation over the WAN as the 300GB dataset has already been recognized by the Global Dedupe store.
Instead, the majority of the data is crossing the WAN at 3Mbps which is what I was hoping to avoid in the first place.
Have I missed something in the process of configuring this? I know from prior experience that moving data around to different VMs typically doesn't cause it to be seen as "new" data, and the Dedupe policy is utilized to full effect, so I'm not sure what that's not occurring now.
Thanks in advance.
