Hello, As you can see from my previous post I had some problems with statistics and all other plesk scheduled task reporting access denied. Now statistics work as all other tasks defined by Plesk except for backup. Problem is when backup process starts it never ends. I can start it manually via scheduled task but same thing happen. If I start application for Plesk backup and after loading config that I need, everything runs ok and without any problems. There is no any logs whatsoever in Event viewer that can point me out in right direction so I'm wondering what could be the problem with plesk backup scheduled task? Once again, thanks for your time and patience.
