Why does gitlab often fail to backup after upgrading to 12.7.9?

When I upgraded gitlab to version 12.7.9, I failed to backup it with the gitlab-bakup create command. The error log is as follows:





The result of running the command:gitlab-rake gitlab:check SANITIZE = true
image




The result of running the command:gitlab-rake gitlab:env:info

Please help to locate the reason. And give me a solution, thank you very much!
