Situation
WD Smartware is a backup application that is designed to automatically protect date through continuous backup initiated whenever changes are made to a file. WDBackupEngine.exe file is a software component of WD SmartWare by Western Digital Technologies
Filr Desktop client can trigger downloads for large numbers of online files when workstation-based applications, such as the WD Smartware request access to them. Downloading the files stored in Net Folders can quickly fill up a local disk. When this happens, end user may experience an unresponsive or very slow system.
When this happens, the ServiceProvider.log file will have lots of entries like these:
