I am just setting up a WSE 2012 R2 server. I can't get the back-ups to work. I believe somehow I have messed up the VSS configuration but uncertain how to correct. I am using the wizard to set up the backup space and have a dedicated drive. It did move it
from F: to an unlettered drive and reformatted it. All seemed well. But all backups fail. The message is Volume Shadow Copy Service error: Unexpected error DeviceIoControl(\\?\Volume{9cabb30b-e17b-4f72-99c8-f6fa4d1829ec} - 000000000000005C,0x0053c008,000000B81E38B960,0,000000B81E38C970,4096,[0]).
hr = 0x80820001, The bootfile is too small to support persistent snapshots.
After poking around I think this information may help:
