Datto and Support for Clustered Shared Volumes (CSVs)



This article provides information about Clustered Shared Volume (CSV) compatibility with the Datto solution.


  • Datto Windows Agent
  • ShadowSnap Agent
  • Microsoft Hyper-V


Due to a technical limitation with Cluster Shared Volumes (CSVs), the Datto solution does not support backing up volumes which use the technology. While backups for systems which use a CSV implementation may work intermittently, the Datto incremental block tracker cannot function consistently or compatibly with the underlying storage, leading to large incremental snapshots and backup failures. Datto Technical Support is unable to support backup or restoration for endpoints in a CSV configuration.
