The Volume Shadow Copy service initially was running under the context of System, so we thought that ‘System’ doesn’t have permissions to access network shares. When the Volume Shadow Copy service was running under the context of System, this was the error logged:
“failed with following error code '0x8078014B' (There was a failure in creating a directory on the backup storage location.).”
Which is likely due to not having permissions to write to the network location. This is a scheduled backup trying to write to a network location, so we changes the service to run under the context of an account that does have permissions to write to the network share. Then the error changed to this:
“failed with following error code '0x8078006B' (Windows Backup failed to create the shared protection point on the source volumes.).”
HRESULT 0x8078006b

We aren’t really seeing anything that gives any hint on what the issue is. Any ideas? Thanks in advance!
