Backing Up the Offline Redo Log Files with BR*Tools

Use

You can use BR*Tools to back up the offline redo log files. BRARCHIVE performs the backup.

The offline redo log files are called the archivelogs in the BRTOOLS menus to save space.

Prerequisites

·        Make sure the database is running in ARCHIVELOG mode. For more information, see Setting Up Archiving.

·        Make sure you have set the necessary BRARCHIVE parameters in the initialization profile init<DBSID>.sap, because BRTOOLS uses these when it calls BRARCHIVE.

·        Make sure you have the right backup volumes. When you back up to tape, make sure that you have read the notes on managing and initializing the tapes. For more information, see Volume Management.

·        Allow enough time for the backup. Hardware compression can halve the backup time.
