Data is the key behind any functioning system.
With the use of hard disk drives, a large amount of data can be stored in a disk
conveniently. As all data can be stored in a single HDD, the possibility of
disk failure poses a new threat to the availability of data. A disk may fail
due to various reasons. Mechanical failure is common in old disks. Other
reasons include natural tragedy like seisms, floods tide, etc.. When sensitive
info is stored in HDD, it becomes essential to reduce the opening of
informations loss. This is accomplished by storing the informations
redundantly. The process of replicating the contents of a information memory
device to another device is called in disc tomography.
What is disk imaging?
It refers to the exact duplicate of the HDD
which contains sensitive information. All data stored on the hard drive is
copied and exact image is taken. Files and copied exactly, verbatim. Image
files are often .iso files in which you will mount using certain software. You
can also burn these iso files to a CD for easy installation and reference in
the future.
How disk imaging software works?
The imaging software
creates a clone using the image of the disk. The software does not create a
backup with the exact information present in HDD. If this has to be done by the
software, then to create a backup of a 80GB hard drive, another 80GB hard drive
would be needed. This is not a viable option. Tomography does not deploy
informations mirroring technique. The software package will make an image of
the disc which is much smaller in size. This ikon can be then used to retrieve
the informations using informations retrieval package.
