I got this error:

The backup operation that started at '?, 2015?, -?, 09?, -?, 10T11:39:36.495517700Z' has failed with following error code '0x8078014B' (There was a failure in creating a directory on the backup storage location.). Please review the event details for a solution, and then rerun the backup operation once the issue is resolved

This was a VM on VMWare. I ended up backing up to a different file path. The only thing I could figure was that the data at old location was corrupted.
Error code 2155347997 - According to ME2182466, you may get this if you have a computer that is running Windows 7 or Windows Server 2008 R2 and you perform a system state backup operation on the computer. A hotfix is available.
Error code 2155348299 - This may indicate a permission issue. Make sure that the backup service is running under the System account and that the System account has all the required rights to the backup data. See also the EV100208 thread.
