Vssadmin doesn't verify that a drive volume is supported for DiffArea
Note The <source drive> placeholder represents a data drive that has BitLocker protection enabled. And the <destination drive> placeholder represents a data drive that has BitLocker protection disabled.
This command runs successfully without errors or warnings.
Important This configuration is not-supported.
The Volume Shadow Copy Service (VSS) UI calls CVssDiffMgmt::QueryVolumesSupportedForDiffAreas() and checks whether a volume is supported for DiffArea. If a volume for DiffArea is encrypted and it's not the same volume, the volume is not listed in the UI.
- A nested volume (such as when the physical volume is the previously mounted volume).
- If the BitLocker-encrypted volume is another volume that's specified as a shadow copy storage area in the source volume.
- If the sector size of the volume of the VSS storage area is larger than the source volume.
