Please help

Start with the supplied docker run command, focusing on the GITLAB_BACKUPS, GITLAB_BACKUP_TIME, and GITLAB_BACKUP_DIR settings and the mounted /home/git/gitlab path. Check the container's mounted logs for backup-related output and verify whether a backup tar is created under the configured directory; the issue is resolved when the scheduled tar appears there.
