restoring and recovering的区别

What is the difference between restoring and recovering?

 

from:

Restoring involves copying backup files from secondary storage (backup media) to disk. This can be done to replace damaged files or to copy/move a database to a new location.

Recovery is the process of applying redo logs to the database to roll it forward. One can  roll-forward until a specific point-in-time (before the disaster occurred), or roll-forward until the last transaction recorded in the log files.
 SQL> connect SYS as SYSDBA
 SQL> RECOVER DATABASE UNTIL TIME '2001-03-06:16:00:00' USING BACKUP CONTROLFILE;

 RMAN> run {
   set until time to_date('04-Aug-2004 00:00:00', 'DD-MON-YYYY HH24:MI:SS');
   restore database;
   recover database;
