Symantec System Recovery (IOCTL_VSNAP_VDIFF_STOP) failed
We are currently using Symantec System Recovery 2011 to backup a database of image files. It has worked perfectly for some time now. But about two weeks ago I started getting the following error.....
Error EC8F17B7: Cannot create recovery points for job: Drive Backup of Storage (E:\).
Error E7B70001: Win32/Win64 API DeviceIoControl(IOCTL_VSNAP_VDIFF_STOP) failed.
Error EBAB03F1: The device does not recognize the command. (UMI:V-281-3215-6071)
Nothing has been updated since I think this product was abandond by Symantec it hasn't seen an update since it was installed. The disk appears to be running fine and error free. I have no idea why this started or how to fix it. A google turned up no results which I don't think has ever happend.
Any input would be greatly appreciated.
