Operating System

Windows Server 2012


Data Deduplication







One or more volumes have minimal available disk space remaining.



If the volumes become full, users or applications may be unable to create or modify files on the volumes.



Use Ddpeval.exe to check if Data Deduplication can free up sufficient disk space on the volume. If so, enable Data Deduplication on the volume using Server Manager. If not, allocate more disk space and extend the volume, move data, or delete data to free up space.
