SnapProtect Configuration - Windows File System iDataAgent

Prerequisites

  • Prior to performing an SnapProtect backup, ensure that all the available hotfixes for Virtual Disk Service (VDS) and VSS are applied.
  • When performing SnapProtect backup for a Windows Cluster, a proxy server must be used for performing backup and restore operations.
  • SnapProtect backup on Windows supports basic disks.
