Managing the desktops’ Operating System and applications is highly critical in any Organization. Managing these includes installations, upgrades and recovery tasks.This article describes some of the basics about OS imaging.

  What is an OS Image?

  • To make a computer up and running in a shot span
  • To provide common operating environment
  • To manage / maintain the machines at an ease
  • Portability
  • Low Cost

  OS Imaging Process

         Imaging is a method of capturing preconfigured operating
     system and software applications onto server as a single file
     unit. A volume Image can be captured in either partition wise
     or disk wise.

          When an image is captured and uploaded to the deployment   
     server or a DVD. These Images can be deployed to machines
     individually or simultaneously (using deployment server).

          Once a machine completes its OS deployment, the machine
     will be ready with all the applications and settings along with
     OS as a replication of the machine from which the Image has 
     been captured.
