Oracle Rac with Recovery

Well, i saw the logs and it´s say its working. The job logs in Rman say it´s working.

But in my Example, the database is about 550 GB, and the backup is doing only 1.6 GB.

Ans:

To verify this why it is only backing up 1.6 GB what happen if you do DBA intiated job using Rman from any one of the nodes and check if it backup 550 gb or 1.6gb

 RUN {
 ALLOCATE CHANNEL ch0 TYPE 'SBT_TAPE';
 BACKUP DATABASE PLUS ARCHIVELOG;
 RELEASE CHANNEL ch0;
 }

Please use the above script to run DBA intiated job

Moreover ,Please let me know the results of Isolation when you have done that

3 Finally to Isolate the issue please try following

From the second node, using the sqlplus connect to the recovery database and check how much time it takes to connect & see how much time it takes ,if it is taking long time ,it is not a backupexec issue then

And finally to answer this question of yours

Q The questions is : with a big database, Backup Exec take a long time to check ? For example, in SQL, it does a physical_check by default.

Ans :

No as like SQL it would not be doing any check so there is something which we need to check.

Hope that helps

Thanks
