    Always plan for the worst. Store data in a safe place

Backup and Recovery

Backup and recovery describes the process of creating and storing copies of data to protect companies against data loss. This is sometimes referred to as operational recovery. Recovery from a backup typically involves restoring the data to the original location, or to an alternate location where it can be used in place of the lost or damaged data.

The purpose of the backup is to create a copy of data that can be recovered in the event of a primary data failure. Primary data failures can be the result of hardware or software failure, data corruption, or a human-caused event, such as a malicious attack (virus or malware) or accidental deletion of data. Backup copies allow data to be restored from an earlier point in time to help the business recover from an unplanned event.

Full

As the name suggests, this refers to the process of copying everything that is considered important and that must not be lost. This type of backup is the first copy and generally the most reliable copy, as it can normally be made without any need for additional tools.

Incremental

This process requires much more care and has to be done over different phases as it involves making copies of the files by taking into account the changes made to them since the previous backup. For example, imagine you have done a full backup. Once you have finished, you decide that going forward you will do incremental backups, and you then create two new files. The incremental backup will discover that all the files in the full backup remain the same, and will only make backup copies of the two newly created files. As such, incremental backup saves time and space, as there will always be fewer files to be backed up than if you were to do a full backup. We recommend that you do not try to employ this type of backup strategy using manual means.

Differential

A differential backup has the same basic structure as an incremental backup. In other words, it involves making copies only of new files or of files that underwent some kind of change. However, with this backup model, all the files created since the original full backup will always be copied again. For the same reasons as with incremental backups, we recommend that differential backups are also not carried out manually.

The general aim of Cybersecurity is to make data safe and secure to keep the company business up and running without any losses. A part of securing any company, is to save its data in a safe place to ensure business continuity.
