When attempting to backup a virtual machine running Microsoft Windows on an ESX host, the backup may complete with the following exception.


Error

[fsys\ntfs\img_pdi]  | Error mounting disk(s): E_IMG_FS_NO_GRT_VOLUMES_FOUND (0xe0009745).


Cause



This has been seen due to configuration or environmental issues with the server in relation to DNS and/or resources.


Solution



Check that server is in domain where VCENTER resides.

Check that there is sufficient memory on the server to handle VMware backups.

Either disable GRT for the VMware backup or perform a standard RAWS backup of the virtual machine
