System images are collected images that contain the contents of a system disk for system recovery.
In Resource Orchestrator, system images (only the host OS when using VMs) are backed up and centrally stored on a disk on the admin server.
Multiple versions of system images can be retained.
Creating backups before any OS or software installation, configuration changes, deletion or patch application can drastically reduce the time necessary to restore a server to its original state if hardware or software problems occur.

Point
This function is also supported for iSCSI boot and EFI environments.
Backup and restore of individual physical servers and VM hosts can be performed.
VM hosts of VMware vSphere 4/5/6 are not the targets of backup and restore.
