How to distribute RMAN backup among tape volumes in OSB
Hi Guys,
I would like to ask some information about OSB. I have finally set up our Oracle Secure Backup 10.3.0.3.0 and initial OSB backup to tape is good using our test environment.
Now, our production servers has the following details:
Serv01
- Oracle Database 11.1.0.7
- Windows Server 2003 R2
- Current RMAN backup to disk full (level 0) is at 2TB.
Serv02
- this is our media server for OSB and we manage from here all other servers that we would like OSB to be implemented.
-Windows Server 2003 R2
- We have IBM tape library here with four drives
- Our tape volumes are 480GB each (compressed) we about 50 of them.
-Each tape volume has barcodes and our library has barcode reader
How can I group certain tapes (as a media family?) and use them for our level 0 backup. As you know, one tape cannot hold our level 0 backup so we need at least 5 tape volumes to hold our level 0 backup. Is there a step by step process of doing this? Or does anyone know how to do this?
Thanks and I would really appreciate your thoughts about this.
Yes, media families (like tape pools) are used to group backups on tape. Using a database backup storage selector, you set-up media policy so OSB will automatically select appropriate storage when for the backup per your settings. You may want to refer to this white paper which discusses media management:

How to move rman backups on tap from disk
Hi,
I have rman backup files on the disk, now how we can move these files to tap. is there any rman command or is there any script to move.
Thank you!Do you use FRA (Flash recovery area)?
If you use FRA then configure RMAN to take backup to tape. And backup fra to tape.
RUN
ALLOCATE CHANNEL ch0 TYPE ‘SBT_TAPE’;
BACKUP RECOVERY AREA;
RELEASE CHANNEL ch0;
If you don't use FRA then you can backup your backupsets which are on the disk to tape.

Hi,
how do we move the backup of the database that has taken by rman to the tap.
Ex:
I have a database and backup has taken by rman by connecting in no catalog mode. like $rman target /
so backup are generated and stored on the disk only.
Now if i want to move these backup file to tap, how we can move these files.
Please let me know
Thank you!See Backups of Backups in the Backup and Recovery doc

Backups of Backup Sets
The RMAN BACKUP BACKUPSET command backs up backup sets that were created on disk. The command is a useful way to spread backups among multiple media.
If RMAN discovers that one copy of a backup set is corrupted or missing, then it searches for other copies of the same backup set. This behavior is similar to the behavior of RMAN when backing up archived redo logs that exist in multiple archiving destinations.
Example 7-2 shows how you might run the BACKUP command weekly as part of the production backup schedule. In this way, you ensure that all your backups exist on both disk and tape.
Example 7-2 Backing Up Backup Sets to Tape
BACKUP DEVICE TYPE DISK AS BACKUPSET
DATABASE PLUS ARCHIVELOG;
BACKUP
DEVICE TYPE sbt
BACKUPSET ALL; # copies backup sets on disk to tape

Hi All,
This's my scenario.
I am using oracle 10gR2 on solaris 10. I configured Rman for my database. I ran the backup command on monday and again tuesday and again today also.
All backups are stored in tape not disk. now I have a problem, so I want to restore the Monday backup from tape.
How to tell these to Rman. If I simply mentioned the restore command, hope Rman will restore the latest backup. But I want to restore the Monday Backup.
Could you anyone help me on this..
Many Thanks
Senthilwhen ever you are recovering the database to certain time,certain scn then it is a incomplete recovery only.
after completing the recovery by specifying until time or until SCN oracle will not allow you to open the database.
It will ask you to open the database in resetlog mode.
The step which admin given is correct one but after that you have to open the db in resetlog mode

How to verify RMAN backup ?
How to verify and validate the RMAN backups on daily basis?One more doubt at this point - if we can't locate any RMAN script in crontab(crontab -l) but still backup is occuring regularly, how can we see the script behind this?
Thanks in advance.

What you want see? If backup was executed without error or make sure that there is a valid backup on tape or disk.
So, If you want see if backup was executed successfull you must find the logs of backup or query "V$RMAN_OUTPUT" (check it on documentation).
If you want check if Database is Valid on Disk or TAPE as mentioned previously "RESTORE VALIDATE DATABASE" (check it on documentation).
Where we can locate RMAN SCRIPT? It's hard to answer.
It' your env, you should find out. The options are: Crontab / Oracle Enteprise Manager / Third-Party Backup Software / Job Scheduler.
Also you can try : Take a time of backup was executed and check on shell a time of exection of backup " ps -ef |grep rman" you will find from where script was started.

Restoring RMAN backup from tape beyond retention policy ??
Hello Friends,
I just stuck in some basic finding. Need your help to resolve the questions.
How we can use RMAN backup to restore oracle database when the RMAN backup pushed to tape already and being a OLD backup ( before retention policy date).
Just to elaborate a more.. Say my retention policy is 3 days. I want to restore from a old backup like 30 days old.
So surely the requesting backup is behind retention date and has been pushed to tape.
Please suggest.
Thanks in advance.

Assuming the actual backup files still exist (the only thing actually deleted is the record of them in the catalog), you can make those files available and use the rman 'catalog' command to re-catalog them. -
Friends,
I have got single instance non-RAC database with datafiles stored in ASM Diskgroup. the RMAN hotbackups are stored in ASM diskgroup on daily basis.
Just wants to know how I can move old backups (previous night) to TAPE every night before kicking off today's backup.
We are using veritas netbackup for tape backups.
Any inputs are appreciated.
KSThe following command backs up to tape all backup sets that do not already exist on device type sbt:
