How Snapshot Client software affects scripts
When you use a script, you must enable the advanced backup method for your clients. Configure this method on the Attributes tab of the policy. At run time, the agent checks the policy attributes to determine if a Snapshot Client backup method is configured and performs a proxy file-based backup.
If you use a script, the script must reside on each client that is included in the policy. Include the RMAN backup proxy command in the script to perform the advanced backup method. Sample scripts are included with the installation.
