Backup Methods
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-andrunning, 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
