Database Backup and Recovery Concepts
To back up your database means to make copies of your data files, control file, and
archived redo log files (if your database runs in ARCHIVELOG mode). Restoring a
database means copying the physical files that comprise the database from a backup
medium, typically disk or tape, to their original or to new locations. Database
recovery is the process of updating database files restored from a backup with the
changes made to the database after the backup by applying incremental backups and
redo logs to the restored files.
