Explanation

Hot backup and cold backup are the two methods deployed for backup. They are based on the state of the application when the backup is performed. In a hot backup, the application is up-and- running, with users accessing their data during the backup process. This method of backup is also referred to as online backup. A cold backup requires the application to be shutdown during the backup process. Hence, this method is also referred to as offline backup. The hot backup of online production data is challenging because data is actively being used and changed. If a file is open, it is normally not backed up during the backup process. In such situations, an open file agent is required to back up the open file. These agents interact directly with the operating system or application and enable the creation of consistent copies of open files. The disadvantage associated with a hot backup is that the agents usually affect the overall application performance. Consistent backups of databases can also be done by using a cold backup. This requires the database to remain inactive during the backup. Of course, the disadvantage of a cold backup is that the database is inaccessible to users during the backup process. All the files must be backed up in the same state for consistent backup of a database that comprises many files
