Configuring VSS/VDS for iSCSI Disks

GuardianOS 7.0 provides VSS and VDS hardware providers to support Microsoft Volume
Shadow Copy Services (VSS) and Virtual Disk Service (VDS) for iSCSI disks.
• The VSS hardware provider provides a mechanism for taking application-consistent
native snapshots of iSCSI disks without performing full application (or system)
shutdown. A snapshot of an iSCSI disk can be automatically created by a backup job
run by a VSS-compatible backup application, so that the job backs up the snapshot
volume rather than the main production volume.
NOTE: VSS iSCSI snapshots are managed by the Windows client and represent the iSCSI disk,
• The VDS hardware provider allows administrators to natively manage SnapServer
iSCSI disks, using any VDS-compliant management console application.
SnapServers support VSS and VDS on the following platforms:

volume as the backup source.
