title: PLESK - No access to Backup Manager
body: <p>On the frontend of the plesk when I go to "Tools" > "Backupmanager" the page loads some <strong>minutes</strong> and then it times just out. 
  On the server via ssh I saw, that the process pmmcli get one more entry for one call of the backupmanager-page. Even killing the process is not going to work except the timeout comes faster. And the pmmcli - process is keeping the machine quite busy after a few tries. </p>
  
  <p>My question is, how I can get the backup manager up running again? </p>
  
  <p>I am still a rookie with server and even more (or less?) with plesk. I beg for your help or some tips please :) </p>
