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 software and hardware elements. These are interlinked by communication channels which are transferring the pieces from one location to another. The flow of data between the various tangible elements is done by the use of information buses. The software applications initiate the processing operations by issuing a series of commands. The commands direct the hardware components on the operation to initiate.

The operating system is the main application within a computer system. It controls all the running applications and defines the memory allocation for each of these programs. It offers a communication interface between the hardware, software and the end-users. The interfaces ensure that there is a good flow of information between different points. The memory allocation ensures that there is no conflict in running of different applications.

A memory segment may be allocated to two or more applications of devices. This results from interference of memory corruption. It happens when a system is corrupted by malicious applications. The applications attack the main memory and then corrupt the critical files used in issuing of commands. The corrupted files then may issue a number of commands to other devices or the programs.

Program and application installation is very critical in memory and application management. The programs are installed systematically in such a way that the critical files are installed first then followed by other applications. The large disk applications are used ion management of storage locations. The large disk system ensures that there are primary and secondary disks. The primary disks are used for holding the temporary information being processed after which this information is transferred to the secondary storage locations.

Disk fragmentation processes often results in partitioning of storage locations. Partitioning of disks results in a number of segments which are can be accessed separately. Fragmentation operations are very critical in memory management. It ensures that if one of disks gets corrupted, others still remain operative. Data can also be transferred from one location to another.

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.

A number of forceful booting operations are used in the data recovery processes. The severely damaged disks may be subjected to forceful booting operations. As the disks slowly boot, the critical files are transferred from the corrupted locations to external locations.
