Hot Backup Copying physical files when the database is up is called hot backup. A hot backup is taking up the backup of the database while it is still up and running. A few systems that need to support continuous operation, it is difficult to bring down the database without interrupting the service provided to the users. In such cases, hot backup approach should be used. While taking the backup, if the database remains open and available to users then this kind of back up is referred to as hot backup. In hot backup, the database has to run all the time due to critical requirements. Because of this there may be changes in the data files while backup is being taken.
