Data Backup and Recovery

Learn about the different data backup and recovery options available today.


Data backup and recovery are two things that are essential to anyone using a computer. This becomes even more important to organizations as there is nothing worse than losing your data. Data maybe lost due to accidental loss due to human error, hardware failures, database corruption and at times even natural disasters. Data that makes up the backbone of any operation needs to be secured so that they are available to you at any given time. There are many different methods by which data can be stored away for future reference. The files can be encrypted, compressed and de-duplicated in addition to open files and live data sources.


The primary function of a backup is to provide data following a disastrous situation or to help with the recovery of a few files in particular which may have been corrupted or accidentally deleted. Backing up files can be done using different techniques. The technique used will depend entirely on the data that is being saved. Data backup can be done on a daily basis and saved by date. Normal full backups and copy backups are two ways to save data. In addition to these two methods differential backups and incremental backups can be used. Differential backups are copies of files that have changed since the last normal backup while incremental backups are designed to store files that have changed since the most recent incremental backup.

  • Regularity of backups
