Unmap disk in Windows VM, then in Horizon click on option “Manage Attachments” -> “Detach Volume”
It is possible to create snapshot of attached volume but if any data are writen on it while creating snapshot, it might result in corrupted volume.

sudo mkdir /my_snapshot1 && sudo mount /dev/vdc1 /my_snapshot1
