Symptoms

The error might be reported during restore to local disk (Microsoft 365 sets protecting OneDrive).

Cause

The DS-Client is configured as a grid and the node processing the restore request does not have permissions to write to the UNC path specified (the '>>' button to select the local disk restore path is grayed out in DS-User since the DS-Client service acocunt does not have permissions to acess it, the UNC path can still be typed in, but the restore will fail with the error above.

Workaround

Ensure that the DS-Client service account has full control permissions on the selected restore path.
