Cold backup, Hot backup,Warm backup

Hi Vikas,


Cold backup is a recovery technique, in which the files must be backed up before the database is restarted at the same time.

Hot backup is a recovery technique for each table space and is taken at the time of accessing and running the database.

Warm back is a recovery technique where all the tables are locked and users cannot access at the time of backing up data. The backup operations can be postponed in case the users are accessing the database. 



Thanks
