Time-based recovery is a recovery technique, using which a database is recovered up to a specified time. For example, if a user mistakenly drops a table, the database administrator will be required to perform an incomplete recovery up to a point in time just before the user dropped the table. The UNTIL TIME clause is used with the RECOVER command in order to specify the time up to which the database is to be recovered. A time-based recovery can be performed manually as well as by using RMAN.
