LMS 3.1 Beckup falied

[NetTeam]

ciao, qualcuno mi sa dire perchè cisco works non mi effettua più il beckup?
Nella cartella del beckup trovo sempre un file chiamato beckup.lock
se lo cancello quando faccio il beckup successivo mi rigenera lo stesso file beckup.lock e cmq non riesco a fare il beckup.
nel log degli errori c'è scritto questo:
