In this cyber age, storerooms containing
piles of files and documents have given
way to hard disks. A 20 GB hard disk
is capable of holding the number of documents
which would require many warehouses to
fill. Thus the security and the well
being of the hard disk are of immense
concern to any computer user. The hard
disk has to be saved from voltage fluctuation,
erratic viruses, overloading and a host
of other factors. In spite of using the
latest technology and other techniques,
hard drive failure is a recurring problem
today. Due to this, computer disk and
data retrieval has been an integral part
of today's computer oriented market.
As long as the market maintains and supports
the mechanical storage device, problems
will keep on occurring.
One possible
option is to have a reliable back up
system of the data. No matter how
well a computer is treated, there’s
no guarantee that it won’t be affected.
The risks are much greater than most people
realize. Data recovery requires knowledge
above and beyond normal hard disk repair.
The damage can be caused by multifarious
factors such as hardware failure, software
corruption, human error, and espionage, and
these reasons drive disaster recovery companies
to utilize the latest as well as the most
proven methods of damage control in the minimum
possible time frame. The company should also
be prepared to work on current and obsolete
hard disk and drive manufacturers with virtually
all operating systems. Their expertise must
cover the application such as MS Windows
XP, ME, NT, 2000, 9X, 3.X, Apple O/S, UNIX
(all flavors), SGI, Novell, OS/2, and MS-DOS
with any combination of interfaces IDE, EIDE
/ ATA, SCSI 1- UW2, SCA, MFM, RLL and ESDI.
Overcoming the challenges posed by all these
systems as well as recovering lost data from
disaster struck spanned sets, mirrored set,
striped set, RAID 0-5 and catastrophically
damaged machines is the hallmark of a champion
disaster recovery champion or technician.
During the recovery operations, engineers
should evaluate the actual byte recovery
to ensure that whatever had sunk is brought
on board.
So let’s glance at the exact
kind of problems faced by engineers and
technicians while retrieving lost data.
Electrical problems
are often difficult to pin down because
software as the designed program can be
graded on
the basis of the skill and expertise of
the programmer, and it is generally limited
to
how the drive is functioning if at all.
Software that does not approve data recovery
will
write a false pattern on the drive to mislead
the user and read it to verify that the
pattern is correct and there is no problem
in the
read-write channels, which in turn will
overwrite the data that was originally
there. This
problem can be averted by making an exact
sector-by-sector image of the drive on
an absolutely separate unit for manipulating
the data fields to ensure that the original
data is never overwritten.
A new method
to retrieve data lost due
to a disaster is done by using Virtual
Machines
(VMs). They are used due to their encapsulation
and standardization of virtual hardware
components, which enable quick recovery
on a diverse
set of hardware platforms leading to
a quicker time to recovery and a significant
drop in
cost for implementation of a disaster
recovery
plan. This process is currently in vogue
because generally a disaster recovery
package comes with a price tag that goes
through
the roof. In the current complex and
diverse server environments, the time and
cost
for disaster recovery planning has climbed.
Virtualization
of servers and storage boosts flexibility,
fault tolerance, and drastically reduces
the complexities of data recovery in
the event of a disaster. The components
affecting
the time to recovery (TTR) are i) setting
up the virtual infrastructure including
virtual servers and storage devices such
as local/NAS/SAN
and networking, ii) recovery after the
disaster by loading the VM disk images
on the storage
devices and the configurations on the
virtual infrastructure services. Generally,
the
restoration time for a 10 GB system using
virtual disks
and storage of images takes a period
of five minutes.
With a handful of tools
and ways to recover lost data, today
the client is spoiled
with choices. Often it is the spiraling
cost which
holds them back from using effective
and latest techniques to cure their
sick units.
So if you want to experience state
of the art technology for recovering important
data that you have lost and other companies
are
charging you a fortune for their services,
then the solution is nearer than you
think. Click

we will respond to your SOS immediately.
