Problem Statement :   Taking back of the data in production system

                       ....ability to restore it asap.

wikipedia definition for 'dd' : dd is a common UNIX program whose primary purpose
                                is the low-level copying and conversion of raw data.
                                dd is an abbreviation for "data definition" in IBM .



'parted' or 'fdisk' : untilties  unix genere of operating systems to 
                      manage disk partioning.


Opportunity: unix utilities like 'dd' ... can be used for disk duplication,

             or specific partitions of the disk.


             Thus a script ...usually a nightly scheduled or other free time ...given
             the limitations of both or all the utilities falling under the category
             ....can be used as a backup script ....by backing up data to a standby
             hard-disk.

             Also to be noted is that when using the above utilities ...usually disk
             partiontions along with labels are duplicated asis ...i.e. creating a
             exact or 100% replica of the source disk ...thus in the un-forseen eventuality
             or a sudden system reboot ....a clash of volume-label may preven the system
             from booting ...unless one of the disk is removed

              ....while the above offer a viable solution for non bootup disks,
              ....for more viable alternative refer elsewhere as part of document below
              or one of the opportunities as published as part of this effort.       


             A notable import thing here ...as part of personal experience ...when systems
             experience a crash ...i noticed MBR being corrupted ....thus making the systems
             unable to mount the boot partitions ....at times having a backup copy of the
             MBR and also the partition table of disk  ....can enable to retrieve the data
             of the disk.      

             
 Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in 
      
       http://uk.geocities.com/ravivenkatus/projects.pdf
       http://ravishankarkv.tripod.com/projects.pdf
        ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
