We tested one script he provided and it did work.
The sample script runs calc.exe when an alarm was triggered.
It did generate lots of calc instances in the Task Manager (both V7 and V8).
Seems script runs in hidden mode on Veeam One server.
However, my goal was to run a .wav file every time an alarm is triggered.
He provided me another script (I really appreciate the support) which plays .wav file.
The script runs as standalone program but not as post script from Veeam server which is a Hyper-V VM by the way.
He's testing this on lab and has yet to get back to me.
Hope he can nail it and make the .wav file play once an alarm is triggered.
Thanks and regards,
