Getting Error at the gitlab backup
Hi,
I did run the below command it works and it says `gitlab reconfigured!`
`sudo gitlab-ctl reconfigure`
### Summary
I'm facing error when I'm running the backup command.
### Steps to reproduce
When you run the command: `sudo gitlab-rake gitlab:backup:create STRATEGY=copy`, you are able to reproduce the issue.
### Relevant logs
I'm getting the below error in the middle of backing up:
```bash
