Hi everybody I'm currently testing Backup Exec 12, and are having some problems with VSS. I do have the open files client installed remotly and locally on the server, but still I get this error. Pretty much the same deal with open files. ADBO: Offhost backup initialization failure on: "\\servername\D:". Snapshot provider error (0xE0008534): Backup Exec could not find a Microsoft Volume Shadow Copy Services (VSS) software or hardware provider on the media server. To use offhost backup, a VSS provider must be installed on both the media server and on the remote computer. Check the Windows Event Viewer for details.
