The Backup Component

1.The database is started up briefly to determine the database files allocated to a tablespace. Normally, several tablespaces are backed up during an archiving process.

2.The database is closed.

3.All the database files of a tablespace are backed up, irrespective of whether system files or raw devices are involved.

!receive an error message at the end of the backup if the database was started up in the meantime.

If you want to back up a database that is currently online under OPS, and

!the instance that is to be used for the backup is offline, that instance can only be started automatically under Oracle 7 and an online backup will be carried out instead. You may get an inconsistent backup under Oracle

8. You should therefore always note under Oracle 8 before the backup that all instances are either offline or online!The database must not be started up during an offline backup! You will

If you use the default configuration described in Chapter 4, a copy of the control file is also made every day, and - when you carry out an offline backup - the online redolog files are also backed up.

Please note that the database is started up briefly once in the course of an offline backup, in order to request the paths to the database files and the raw devices. This alters the time-stamps on the database files and the control file. It follows that the state of the database after an offline backup will not be identical to its state before the backup.

If you want to make a snapshot of your database so that you can exactly recreate its current state at some later time, we recommend you use one of the following two procedures, which are carried out while the database is stopped:

1.Back up all the tablespaces, the online redolog files and the control file directly, using NetWorker (i.e. without using NSR-ORA). You will need to know all the necessary pathnames in order to do this.

2.Then carry out the backup using NSR-ORA and the save set

/nsr/oracle/$ORACLE_SID/${ORACLE_SID}_full_save. This ensures that the control file and redolog files are only backed up after the tablespaces, so that the time-stamps of the control file will be as expected by ORACLE.
