Oracle database – What is the difference between restoring and recovering?


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. The data file is at a prior point of time than the current database.

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, or roll-forward until the last transaction recorded in the log files.
