Backup Error

I’ve read the docs about the errors ‘Job “Database Backup (Weekly)” has started, but not responded for 10 seconds. Please check information.’ but it doesn’t help me solve it.

This is the info I have when I check info. It shows as ‘ok’. What can I do to fix this? I’m using manual database backup when it’s causing the error.
