Backup software help businesses prevent data from becoming inaccessible in case of natural or manmade disasters by maintaining a copy of data from servers, devices, databases etc. on to cloud or to a different physical location. If there’s a mishap, data can be restored to its previous state if there’s a backup. There are different mechanisms of data backup – cloud storage, disk-to-disk etc. This category may include some Disaster Recovery (DR) software and tools too.
