SharePoint Crawl "paused by system" - can't resume via PowerShell

Hi

My Sharepoint crawls get "paused by system" because of our back-up tool (Symantec Back-up Exec).
Symantec is aware of this issue.

I have tried to restart the crawl by using this PowerShell guide:

For Crawls that haven't been "paused by system" this works perfectly. But for my situation it doesn't.

The only way to get the crawl to restart again is to manually click on "Start all crawls". But when the next back-up runs it get paused again.
So every evening I need to log on to the central administration and click the "Start all crawls" button (This is quite annoying).
When clicking on this you get the following message:

If you click "Ok" the Crawl starts running again like normal (until it get paused again when the next back-up runs).

Is there anychance that i can resume the crawl using PowerShell or any other scripting language/ or simulate the click on "Start all crawls" button?

Thanks in advance.
