An Analysis Of Data Recovery

By Angela Briggs


Different pieces of information may be lost when a computer system fails. The system fails as a result of a number of attacks. The attacks may occur when a system get infected by various malicious programs. This corrupts the disk storage applications leading to loss of information in such locations. Data recovery activities are aimed at salvaging the information in the corrupted disk segments. A number of approaches may be used in such a case.

A computer system is made up of many components. The hardware components comprises of all the tangible elements within a system. These are interlinked with each other. The software element provides a platform of running the computer. The programs installed within a system are used for running various operations. The instructions issued are interpreted and then executed leading to a number of operations.

The main program within a computer system is the operating system. This application controls and manages all the processes within a computer system. The coordination of instruction issuing is done by this core application. It also manages the memory such that each of the elements under its controls is allocated a special memory segment. This ensures that there are no conflicts during the processing.

Conflicting instruction may be sometimes issued. This happens when the same memory segment is allocated to a number of computer elements. This result in freezing of applications may cause a failure in the storage locations if it is severe. Malicious applications may also launch an attack on the main memory. This corrupts the memory. A series of harmful instruction may be given to storage locations such that a failure may also occur. This ends up corrupting the information stored here.

Program installation procedures are very critical. The main and key files are installed first. This is done sequentially in way that allows for a disk processes. The rest of program files are installed afterwards. Execution is also done sequentially. Large disks are critical in information recovery. The main disks holds data being processed after which it is transferred to external locations.

Fragmentation of the primary and secondary storage location is very critical in information management. The fragmentation partitions the disks into a number of independent segments. Each is accessed in a different way. Management is eased through disk fragmentation. This also ensures that in an event that one of the segment collapses, the other one is not affected. The flow of information is therefore not affected.

The level of attacks by the malicious applications on the main memory differs depending on the type. A mild attack slows down the operations of storing and retrieving the information. This gives time for the data to be backed up. A severe attack may completely damage the storage locations such that the information gets lost completely. Some processes launched may allow for some of information to be transferred to a number of external locations.

Data recovery operations may incorporate a series of forceful booting in the event that a severe attack occurs. The storage disks which have been corrupted are subjected to forceful booting. This process slows down the rate of erasing data. In the process some of information is slowly retrieved as the dead segments comes alive.
