IT Process Automation

Is there any command at the prompt, function inside the PAM itself that runs Process Export?
I need to eventually back up the processes and want to automate the backup process without having to connect to the database silo.

Everton,

There are web service calls that can be used to export processes or folders:

SOAP API Reference - exportObject Method

Export a Folder or a Document using the Open REST API.

You could build a process that exports your library, or portions of your library, and build a schedule have that as you require.  

Please keep in mind that in order for Process Automation to import a library XML file it must be under 250mb in size.   The export cannot determine how large the xml file will ultimately be and can, if your library is large enough, create an export that is larger than 250mb.   You will need to do some manual exports, verify the size, and if it is over, or near 250mb, find a way to reduce the xml size; for example by exporting individual folders from your library instead of the root of the library.
