Recovery Manager and Third-Party Backup Tools
Recovery Manager for Oracle User’s Guide
■ The database instance must be CLOSED for this operation. If the database is an RAC
database, all RAC instances must be CLOSED.
■ The base (datafile and/or archive log) virtual volumes must be temporarily removed from
the primary (database) server.
■ The specified virtual copy must have an Available status (not mounted).
Recovery Manager saves an ASCII control file and a binary control file for each created virtual
copy in its repository. After a rollback, you may need to restore the control file in order to
perform database recovery.
2.10 Recovery Manager and Third-Party Backup Tools
3PAR Recovery Manager integrates 3PAR Virtual Copy with Veritas NetBackup (NBU) and/or
Oracle RMAN to perform off-host backup. Off-host backups can dramatically reduce
performance impact on the primary host and minimize database down time or database in
backup mode during backup.
Recovery Manager creates a virtual copy (snapshot) of the database, mounts it to the backup
host, then performs backup of the virtual copy.
Recovery Manager supports online(hot), offline(cold), datafile, or archive log backups.
■ Online backup - A database backup while it is OPEN.
■ Offline backup - A database backup while it is CLOSED.
■ Datafile backup - A backup of datafiles only.
■ Archive log backup - A backup of archive logs only.
Recovery Manager can be configured to perform either NBU (user-managed) backup or Oracle
RMAN backup (See 4.9 Recovery Manager Configuration Files on page 4.27 for details).
2.10.1 The Database Backup Utility
3PAR Recovery Manager’s database backup utility supports full and/or incremental backup of
an Oracle database or archive log destination. Full backup of an Oracle database or archive log
destination are always supported regardless of backup method (NBU backup or Oracle RMAN
backup). However, incremental (differential or cumulative) backup of a whole Oracle database
is only available using Oracle RMAN backup. Incremental (differential or cumulative) backup of
archive log destination is only available for the NBU (user-managed) backup method.
