How to prevent client to enter standby mode while backup exec agent is active?

Hi,

I'm using BE 2010-R3 Rev. 5204 on my Win2K3 serve and same for BE-Agent ob my german Win7 64 bit machine.

How can I prevent that Win7 enters standby mode while a backup job is active? Ok I could reconfigure the client to not use any energy saving setting but this is not a solution, just a work arround. I thought that BE-Agent should be smart enough to handle this itsself.

I read a thread on creating a pre-/post-backup script but don't know how to do this (possibly power script). Unfortunately the solution was not posted to this thread.

Thanks for nay help,

Stefan
