Backup and Recovery
As every database administrator knows, backing up a database is a rather mundane
but necessary task. An improper backup makes recovery difficult, if not impossible.
Unfortunately, people often realize the extreme importance of this everyday task only
after losing business-critical data resulting from a failure of a related system.
The following sections introduce some features used in performing database backup
operations. We discuss backup and recovery strategies and options in much greater
detail in Chapter 11.
Recovery Manager
Typical kinds of backups include complete database backups (the most common
type), tablespace backups, datafile backups, control file backups, and archivelog
backups. Oracle8 introduced the Recovery Manager (RMAN) for the server-managed
backup and recovery of the database, leveraging a Recovery Catalog stored in the
database.
