snapshot automatic and manual not working

Hello, a couple of dayss ago Predrag from support helped me with one of my sites having an automatic and manual backup issue.
Today, my other site whose backup was supposed to run did not run and i tries to run it manually but i kept getting the same error the previous problem that predrag solved for me.

I had been waiting for the backup to occur before i uodated my plugins, now i have been set back. Please help me rwsolve this quickly for me to update my plugins .
