MySQL restore dump takes too long to complete, how DBAs deal/replicate large databases?
Large databases should be backed up physically (i.e by copying the physical database files) instead of  logically (i.e by exporting in SQL or something similar). If you use Oracle MySQL Community Edition, you should use xtrabackup. If you use MariaDB there is a integrated feature in the last releases: https://mariadb.com/kb/en/mariabackup/.
