you for reaching out on the community and telling us about your issue. I do
apologize for the issue you're having. That is quite odd you can only do backups on exit now. Lets try running the mondo patch to see if we're able to get your backups working again. I'll leave the steps down below.
Once you've had the chance let us know if you're able to get your backups working. If not we'll see what we can try next.
