Hello Backup Experts,
I have some questions about backup & restore of deduplicated VHDX. First, a few information about the running infrastructure:
We are operating a Windows Server 2012 R2 as Storage Server, providing an iSCSI volume to our Hyper-V Cluster. This volume has enabled the Server 2012 deduplication feature for the VHDX.
First question: Is it recommended to turn of Backup Compression in this scenario? I have noticed, that with setting compression to "optimal", backup time increases significant.
Second question: How is a full VM restore handled, as VHDX files are deduped on storage level?
Thank you in advance.
