RMAN Backup [message #350910]

Hi to everyone,

I am new to Oracle and I would like to ask you something regarding Backup using RMAN.

I have created a weekly script using RMAN commands to take Incremental level 0 backup.
The script before taking the next weekly backup deletes the previous for disk space reasons (not enough space for 2 backups). Each backup is about 75GB.

What I would like to do is before deleting the last backup and taking the next backup all the previous backup files and Archivelogs to be copied to another local disk, to a specific path.

I tried to put a 'cp' command but the backup is using RMAN and it does not of course understand the cp command.

Is there any similar copy command for RMAN or what can I do to copy it somewhere before deleting it from script.

Of course I could do that manually but it is not possible!!

Thanks
Mary

You could copy the files with an O/S copy command and then use RMAN to remove the backups prior to performing the new backup. Another option would be to use BACKUP BACKUPSET command to "copy" the backups to another area and then use RMAN to delete the local version.

Thanks for the answer,

The thing is that my script is being called from rman and a cp command is not accepted in the script.

The script contains the following line to call the script:
/uorabin/app/oracle/product/9.2/bin/rman @/home/oracle/backup

so if I put a cp /u04/Backup/* /u03/BACKUP/ before the following commands:
connect target sys/manager
delete backup;
delete archivelog all;
backup incremental level 0 database plus archivelog;
exit;

the cp command cannot be read.

If you are using crontab to run your script, just add the cp portion right before rman is executed.

------- example backup script that crontab calls --------
# copy previous backup
cp -p /u04/Backup/* /u03/BACKUP/

# perform current backup
/uorabin/app/oracle/product/9.2/bin/rman @/home/oracle/backup
