this report that script exit with code 3 and if lunched mannualy it runs!
and another one that non report anything and not working either manually and is not giving any error in powershell ide:
cmd:
For the powershell script i found out that i have to use Get-VBRTapeJob for tape job but if i lunch it mannualy without administrator priviledges i get Start-VBRJob : Access denied.
Correct, you have to use Get-VBRTapeJob to return tape jobs. Also, -FullBackup switch is not needed (it doesn't do anything for tape jobs). Administrator permissions are also necessary, so make sure that account under which the scripts are executed doesn't lack those.
1) Either execute a required job within the script, between pre and post activities of your choice. Schedule this script via Task Scheduler.
2) Or set scripts as pre and post job activities in backup server UI. Make sure Veeam service account does not lack necessary permissions
