How to automate a selection list in Backup Exec 2012 using PowerShell

Hi,

My client is running Backup Exec 2012 (14.0 Rev. 1798) 64-bit on Windows Server 2008 R2 Data Centre Edition.

I have a backup job that runs daily and is about 1Tb in size. All the data to be backed up is on the local drive (files and folders).

The list of files to be backed up each day changes (files are created by an application and gives them randonmly generated file names) and so I find myself having to go into the job and manually edit the selections each day prior to the job running.

Not all the files in the folder are to be backed up and moving the files I do want to backup out into another directory will cause the application to stop functioning.

I searched the forums and found this article on setting up BEMCLI in Powershell

https://www-secure.symantec.com/connect/articles/preparing-your-powershell-environment-run-bemcli-and-scripts

I have followed these instructions but I'm not sure what to do next as I'm a complete Powershell virgin...

I would appreciate some advice in how to begin writing a Powershell script that will select the files I want to backup each day for me or perhaps there is another solution that doesnt required a script to achieve what I want.

Thanks for your time.
