Computer disaster recovery is the process of recovering data after a disaster. Options include external hard drives, recovery discs, and internet data recovery services. Sophisticated computer data organization increases the risk of data loss. Regularly backing up important data is essential, and recovery discs are an old but reliable option. External hard drives provide redundancy, but can also fail. Data recovery facilities are expensive and not guaranteed. Cloud computing offers remote storage and encryption methods for security.
Computers are vulnerable to disasters that result in data loss. Software can become corrupted, rendering files unusable. Data storage devices or other hardware can fail, making files inaccessible by normal means. Computer disaster recovery is the process by which data is recovered and made accessible, usually and hopefully in the same form as before the disaster occurred. Disaster recovery options include the use of external hard drives, recovery discs, and Internet data recovery services, as well as other means of data recovery.
The organization of computer data has become very sophisticated, increasing the likelihood of serious problems such as data loss. Large operating systems and databases are especially vulnerable to this. Hard drive failure, user error, malicious attacks, and errors in programming logic put a computer at risk of disaster.
A computer disaster recovery plan is an integral part of computer ownership and operation if a user plans to restore lost data in the event of a disaster. Regularly backing up important data is part of this plan. There are several options for doing this, depending on the type and amount of data being backed up, as well as the intended method for disaster recovery of the computer.
One of the oldest forms of computer disaster recovery is the use of recovery discs. Recovery discs are usually made when the computer is new and hasn’t been modified to meet the needs of a specific user. These disks contain an original copy of the state of the operating system and can also store utilities and bundled software. During disaster recovery of your computer, a program designed to recover data installs the files contained on the disks onto your computer’s hard drive.
Some people may use external hard drives to back up files. This has the advantage of providing a redundant system in case of data loss. Files unrelated to the computer’s operating environment are usually backed up to external hard drives. They could also be used to back up sensitive information in case it is lost due to other factors than hard drive or operating system failure. The main disadvantage of using external hard drives is that they can also crash as easily and unexpectedly as an internal hard drive can.
If an individual or organization loses critical data due to a dead hard drive and has not taken backups, another option may be to take the failed hard drive to a facility that has the tools, environment, and skills to attempt to copy the data to undamaged media. The data must be extremely important, otherwise the user of this type of computer disaster recovery must have a large amount of money to justify the high cost. There is no guarantee that all files will be recovered.
The Internet is a popular means of planning for computer disaster recovery. Called cloud computing, such online services range from simple remote file storage to sophisticated hard drive imaging services designed to restore documents, system files, and user settings. The question of privacy and security arises spontaneously. Remote data storage services are aware of this and provide encryption methods to ensure that data can neither be intercepted during transfer to or from remote computers nor infiltrated after upload is complete.
