Hello!
Today I tried to backup with Windows Backup my clustered virtual machine "MAIL" that's stored on two CSV volumes: MAIL's disk C: = vhdx-file stored on CSV Volume2 (iSCSI LUN 2), MAIL's disk D: = vhdx-file stored on CSV Volume1 (iSCSI LUN 1).
The backup completed with warnings:

*-----------------------------*
Now I can't understand the following:
According to the "Details" dialog the total amount of transferred data = the total of MAIL' disk C + MAIL's disk D; but according the log both of the vhd files were not copied:New Virtual Hard Disk.vhdx (disk D:) andVirtual Hard Disks\\MAIL.vhdx (disk C:). The size of the resulting WindowImageBackup folder is only 8 GB, so
1) why these vhdx files have not been backed up
2) is it by design to show amount of data transferred regardless of the actual amount of data being backed up
3) After backup MAIL' disk C: is showing as "Offline" while vm "MAIL" is fully operational - is it a bug?
Thank you in advance,
Michael
