What is Really Back up?
In information technology, a backup, or data backup is a copy of computer data taken and stored elsewhere so that it may be used to restore the original after a data loss event. The verb form, referring to the process of doing so, is “back up”, whereas the noun and adjective form is “backup”.
Backup refers to the process of making copies of data or data files to use in the event the original data or data files are lost or destroyed. Secondly, a backup may refer to making copies for historical purposes, such as for longitudinal studies, statistics or for historical records or to meet the requirements of a data retention policy. Many applications, especially in a Windows environment, produce backup files using the .BAK file extension.
The Backup can be done in any shape or forms.Different types of software and hardware used to back up the information.
Why should I back up my data?
A computer or server could stop working at any time and data on a hard drive could become corrupted or lost if the hard drive fails. When hardware or the computer stops working, data on the computer could be lost. Any files that are important to you should be backed up to prevent loss of data and ensure you can recover those files if needed. There is no Substitute for Good Backup.
A backup is a copy of important data that is stored other on an alternative location, so it can be recovered if deleted or it becomes corrupted. Depending on how often the data changes, how valuable it is, and how long it takes to back up determines how often to backup.
For example, a company with customer records that change frequently may back up their data every few hours. Even more sensitive data such as bank records may be stored on RAID drives that help protect the data even if a drive fails.
Today, there are dozens of different ways to back up your information and mediums to keep your data. For example USB thumb drives, external drives, and in the cloud are some of the most popular places to backup your data.
- Full backup: What is really Full Backup. This Backup captures a copy of an entire data on that Device , Computer or Server. Although considered to be the most reliable backup method, performing a full backup is time-consuming and requires a large number of Hard disks. Most organizations run full backups only periodically to make sure they have the complete copy of the backup.
- Incremental backup is the 2nd most used backup this backup offers an alternative to full backups by backing up only the data that has changed since the last full backup. The drawback is that a full restore takes longer if an incremental-based data backup copy is used for recovery.
- Differential backup copies data changed since the last full backup. This enables a full restore to occur more quickly by requiring only the last full backup and the last differential backup. For example, if you create a full backup on Monday, the Tuesday backup would, at that point, be similar to an incremental backup. Wednesday’s backup would then back up the differential that has changed since Monday’s full backup. The downside is that progressive growth of differential backups tends to adversely affect your backup window. A differential backup spawns a file by combining an earlier complete copy of it with one or more incremental copies created at a later time. The assembled file is not a direct copy of any single current or previously created file, but rather synthesized from the original file and any subsequent modifications to that file.
