Yeah, you should make your own support post rather than commenting on a solved one
the solution is not working because this file is nowhere, its not a different issue its the same, the .backupExclude is nowhere in the server so what exactly to delete to fix this issue! 1 week ago i managed to mak a back up, now after a reboot cannot , what do you suppose to do?
Create your own post and someone can lend a hand
