# Performing an incremental backup of a tenant database
<a name="Appendix.Oracle.CommonDBATasks.BackupTenantDatabaseIncremental"></a>

You can perform an incremental backup of the current tenant database in your CDB. Use the Amazon RDS procedure `rdsadmin.rdsadmin_rman_util.backup_tenant_incremental`.

For more information about incremental backups, see [Incremental backups](https://docs.oracle.com/database/121/RCMRF/rcmsynta006.htm#GUID-73642FF2-43C5-48B2-9969-99001C52EB50__BGBHABHH) in the Oracle Database documentation.

This procedure applies only to the current tenant database and uses the following common parameters for RMAN tasks:
+ `p_owner`
+ `p_directory_name`
+ `p_label`
+ `p_parallel`
+ `p_section_size_mb`
+ `p_include_archive_logs`
+ `p_include_controlfile`
+ `p_optimize`
+ `p_compress`
+ `p_rman_to_dbms_output`
+ `p_tag`

For more information, see [Common parameters for RMAN procedures](Appendix.Oracle.CommonDBATasks.CommonParameters.md).

This procedure is supported for the following Amazon RDS for Oracle DB engine versions:
+ Oracle Database 21c (21.0.0) CDB
+ Oracle Database 19c (19.0.0) CDB

This procedure also uses the following additional parameter.


****  

| Parameter name | Data type | Valid values | Default | Required | Description | 
| --- | --- | --- | --- | --- | --- | 
|  `p_level`  |  number  |  `0`, `1`  |  `0`  |  No  |  Specify `0` to enable a full incremental backup. Specify `1` to enable a non-cumulative incremental backup.  | 

The following example performs an incremental backup of the current tenant database using the specified values for the parameters.

```
BEGIN
    rdsadmin.rdsadmin_rman_util.backup_tenant_incremental(
        p_owner               => 'SYS', 
        p_directory_name      => 'MYDIRECTORY',
        p_level               => 1,
        p_parallel            => 4,  
        p_section_size_mb     => 10,
        p_tag                 => 'MY_INCREMENTAL_BACKUP',
        p_rman_to_dbms_output => FALSE);
END;
/
