Net Recovery Guard is an innovative hard disk protection system. By adopting one hardware card (called Net Recovery Guard Card), seamlessly integrating the network card and recovery card, the Active Workstation can remotely control all Passive Workstations by setting parameters, executing NetCopy, making schedules, running commands, synchronizing computer time and CMOS, or performing other operations. In this way, via network, the Active Workstation can uniformly achieve hard disk protection for each Passive Workstation. Thus directly through operations on the Active Workstation, the system can protect each Passive Workstation's Hard Disk Drive from virus attacks, accidental file deletions/overwriting, failed software installations, system corruptions or crashes, etc. mail: sentrybrand(at)hotmail.com
