Thank you for your answer.
I´ve implemented the script as post script.
Means DP will backup nothing, just execut the script.
But one question. Some of our DB´s are bigger than 2 TB. The Validation Job runs 10 hours and more.
Does this mean, i have to set the ScriptOutputTimeout to 600 and more?
Does this timeout ignore the output of my script:"in progress" ?
I thought the timeout will check the output every 10 minutes and will reverse the timeout?
