2 months ago set up Back up exec, it was going great then for the last pass week any tape I stick in there I can only get one backup on it When I try get another night's on it it gives me the overwrite protection message. Now I know I did not go into the program to change anything, but everyday I go in there to see if I can correct the problem. after a week of doing this I am at my wits end. Does anyone have any helpful ideas?
