Hi Leonid. You are right that VSS will not be seen as ZFS snapshots. When doing a backup you create a VSS shadow copy, then you take a ZFS snapshot of the volume(s). When you want to restore, you attach the ZFS volume(s) to the Windows host, then you assign a drive letter to the VSS shadow copy. In essence it becomes a two step process. This document describes it pretty well: http://www.equallogic.com/resourcecenter/assetview.aspx?id=5305 Geoff _______________________________________________ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
