Enabling Multiple Oracle Backup Copies Using RMAN

Create multiple copies of the data or log backups by using the RMAN commands. During a restores operation, if one of the copies is missing or corrupted, the restore operation automatically performs a failover to the other copy and can then restore the data.

Procedure

Edit the Oracle pfile or SP file and set the BACKUP_TAPE_IO_SLAVES initial parameter to TRUE.
Configure device type. On the RMAN command line, type the following command.

Example
```
RMAN> CONFIGURE DEVICE TYPE 'SBT_TAPE' PARALLELISM 2 BACKUP TYPE TO BACKUPSET;
```
Specify two copies of data. On the RMAN command line, type the following command.

Example
```
RMAN> CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE 'SBT_TAPE' TO 2;
```
Specify two copies of log backups. On the RMAN command line, type the following command.

Example
```
RMAN> CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE 'SBT_TAPE' TO 2;
```
Add the environmental variables for the client and instance where the Oracle instance is installed. On the RMAN command line, type the following command.

Example
```
 
configure channel ch1 type 'sbt_tape' 
 PARMS="software_installation_path/Base/libobk.so,
 ENV=(CvClientName=client_name,
 CvInstanceName=instance_name)"
```

What to Do Next
