That's exactly how the LUNs are presented. In Veeam, when I right click a Hyper-V host > Manage Volumes, I can see the C: drive and the LUN paths (C:\ClusterStorage\Volume#) seperately. I can change the concurrent VSS snapshots for them, etc.
However in windows, when I right click a volume > Configure Shadow Copies..., I only get the C: drive to change its settings.
That's why I'm asking 15-20% of which volume should I take in my calculations. Only the C: drive? or all the LUNs which is not logical because 20% of all LUNs = 4.5TB and the C: drive is only 250GB (the only drive that appears in the "Configure Shadow Copies..." window, that I can change the VSS limit for).
If you can help me with this I would really appreciate it.
Thank you in advance
