Data backup and recovery is the process of backing up your data in the event of a loss and setting up secure systems that allow you to recover your data as a result. Data backup requires the copying and archiving of computer data to make it accessible in case of data corruption or deletion. You can only recover data from an earlier time if you have backed it up. Data backup is one form of disaster recovery making it is an essential part of any sensible disaster recovery plan. Backing up data cannot always restore all of your system’s data and settings. For instance, computer clusters, database servers, or active directory servers may need additional types of disaster recovery since a backup and recovery may not entirely reconstitute them fully. Today, you can back up a significant deal of data using cloud storage; therefore, archiving your data on a local system’s hard drive or external storage is not necessary. What’s more, you can set up your mobile devices using cloud technologies to allow automatic data recovery.
