Answer 1

If you want to keep both server/db in sync then best option is master/slave replication.

But if you don't want to setup replication then you can use a script, which will take dump from server1/db1 and restore on server2/db2 on daily basis, even you can avoid locking on your production server by --single-transaction option.

You can use below statement in your script and schedule it in less traffic hours (night) through cronjob.

mysqldump --single-transaction -h server1_ip -uroot -proot123 mydb1 table1 table2 table3 | mysql -h server2_ip -uroot -p root123 mydb2
