What locking mechanism is used for database backup and restore and Master-Slave Replication?

[John Mitchell <mitchelljj98@xxxxxxxxx>]

Hi,

In reading the documentation it states that the SQL dump backup does not block other operations on the database while it is working.

I presume that while a restore is occurring that no reads or updates are allowed against the restored database.

What locking mechanism is used for Master-Slave Replication?

Thanks,
