What Is Computer Backup In Information Technology, a backup, or the process of backing up, refers to the copying and archiving of computer data so it may be used to restore the original after a data loss event. The verb form is to back up in two words, whereas the noun is backup. Creating a computer backup of original content means having that data saved in two places, but it’s also important to make sure that those two places aren’t on the same device. For example, if you have 3 copies of a working document on your computer, if your computer hard drive crashes, you will still lose all three. This makes the backup method and medium, an important thing to consider for your backup strategy! Reasons Why You Must Have A Computer Backup It’s not a question to ask “IF your computer hard drive will fail, but WHEN”. While there is a certain amount of humor in this statement, the unfortunate reality is that Hard drive failure and other similar problems are inevitable and more common than many people realize. Computer Backup have two distinct purposes. The primary purpose is to recover data after its loss, be it by data deletion or data corruption. Data loss can be a common experience of computer users; a 2008 survey found that 66% of respondents had lost files on their home PC. The secondary purpose of computer backup is to recover data from an earlier time, according to a user-defined data retention policy, typically configured within a backup application for how long copies of data are required. Though backups represent a simple form of disaster recovery, and should be part of any disaster recovery plan, backups by themselves should not be considered a complete disaster recovery plan. One reason for this is that not all backup systems are able to reconstitute a computer system or other complex configuration such as a computer cluster, active directory server, or database server by simply restoring data from a backup. Other Common Important Reasons For A Computer Backup 1. Destroyed Files Aren’t Always Recoverable: Destroyed computer hard driveWhile a skilled computer repair specialist can recover the majority of lost files, there are times when destroyed files or deleted files simply cannot be recovered. When you take the time to periodically backup data, you can easily bring back the files that have been lost. 2. Hard drive failure: Hard drive failureHard drives have a finite lifetime and can fail suddenly and without warning. The sudden death of a hard drive can cause the painful loss of months or years of irreplaceable files and the timing can be catastrophic – if this happens close to a work or college deadline it could be a nightmare scenario. 3. Virus Attack: Virus attackAggressive malicious viruses can corrupt files and disable computers. 4. Theft: Computer theft Computers are sought after by thieves and cannot always be kept secure whilst travelling. The bottom line is that if you value what’s kept on your computer, it’s wise to take steps to protect your information from sudden loss. Work can be redone, but the loss of cherished files like family and travel photos is permanent. Many users regularly backup their files to their computer hard drive, but in the event of a total computer breakdown this will not protect the information. Saving data to a separate location makes far more sense, and can be easily done if you have an external hard drive, or a large-capacity pen drive to back up onto. However this method is only as secure as the device you’re backing up to. When saving your files on physical devices, your backup device needs to be kept in a different location than your computer, and can in turn fall victim to damage or loss. In addition, despite your best intentions, you may forget to copy your files as often as you should, leaving a large amount of recent work unprotected. A safer and more effective method of securing files is online backup. Files stored online are safe from damage your computer, and if something goes wrong with your machine you will still have remote access to your information from any computer with internet access. This means files can be quickly and easily restored to your computer from a secure online server. 5. Humans are Known to Make Mistakes Human error on computer Whether you accidentally spilled coffee on your laptop’s keyboard, you failed to update your virus protection or you simply pressed the “delete” key at the wrong time, you are human and you will make mistakes on occasion. While a computer repair specialist might be able to undelete files and recover destroyed files, you will rest a whole lot easier if you backup data before these problems ever occur. This way, you will save yourself money and heartache when all of your files are right where you left them on your backup device or server.
