Cannot back up to a mounted Windows server

When I specify the shared folder of the mounted Windows server as the backup file creation destination of GitLab and execute the backup, the following error occurs and it fails.
The expected value is that a backup file will be created in the mounted shared folder (/ mnt / gitlab / backups).

[root@autoid-softdev2 backups]# gitlab-rake gitlab:backup:create
