MARS Agent Shadow Copy Storage Warnings

Question

Backups are working well but I am getting the following alert: "You have used 91% of disc space on C:\ allocated for shadow copy storage;"

I have configured shadow storage to use a spare 4TB drive (S) using VSSADMIN:

Shadow Copy Storage association
For volume: (C:)\?\Volume{a209e134-f13c-4e73-8df4-24ffc9f3eb4f}\
Shadow Copy Storage volume: (S:)\?\Volume{358fe664-1dd2-4d5c-8335-ebb4c2bdb7f1}\
Used Shadow Copy Storage space: 31.0 GB (0%)
Allocated Shadow Copy Storage space: 33.9 GB (0%)
Maximum Shadow Copy Storage space: 100 GB (2%)

It seems the 91% is coming from "Used" / "Allocated" (31.0 / 33.9 = 0.914) and not the 100GB I have set as maximum (31.0 / 100.0 = 0.31).

Is this a real issue or is it a bug in the calculation? How can I make VSS use more of the 100GB?
