Result	OK	OK	Fail	Fail	OK

To resolve this behavior, save any dummy file to the volume that contains the log files, so that the Volume Shadow Copy Service, which was first used to back up the Active Directory database and the log files in SP1, will backup the volume.

NOTE: See How can I move the Active Directory database and/or log files to a different partition?

NOTE: You can also use a 3rd party backup solution, like Yosemite TapeWare or UltraBac.
