This is the age of computers and the Internet. Everything can be found online today. People all over the world use words such as 'hardware', 'software', 'anti-virus', and 'data recovery'. Around five decades ago, nobody knew these words, let alone used them.
Prior to the age of computers, physical files were stored. Now, these files are saved on computers on hard disks and other storage instruments. This is a simple way of saving data. However, the computer is a machine. It can fail at any time. During such an eventuality, there is a chance that data will be lost.
However, inaccessible data can be salvaged from corrupted or damaged computers. Data recovery is the name given to this process. There are usually three common scenarios where recovery may be required:
• System failure: operating system failure, malfunctioning of storage devices, and incidental deletions are some of the major causes of data loss. This usually happens on a computer system with a single drive or partition. The best way to recover data under such circumstances is to copy all the essential files onto another storage device. Installing a disk partitioning system, which provides an alternate disk on to which copy the essential files, can mitigate such risks. Here, lost data can be easily recovered.
• Drive Failure: this is a dangerous kind of data loss. Damage to the hard drive makes data recovery difficult. The hard disk stores the data. Damage to the hard disk can result in permanent loss of data. Solutions range from repairing the file system, partition table, or master boot record. The hard disk can be replaced and a one-time recovery of salvageable data conducted.
• Deletion of files: sometimes, files may be deleted accidentally. However, the system does not remove the files immediately from the drive. The deletion only removes the file references in the directory structure. A normal person may not be able to access the files. However, a trained computer engineer can conduct data recovery in such situations.
Necessity for data recovery
Today everyone uses computers to store data, from national secrets to financial data. A disaster can happen at any time. The importance of stored data is the prime reason for data recovery.
Frequent backup of data is required to prevent data loss. However, an effective recovery plan should be in operation. Every organization in the world has a disaster management system in place today.
Recovery of data is an important aspect of disaster planning. There can be huge repercussions for data loss. Here, it is imperative for every organization to have an effective data recovery system.
