A Couple Of Ways To Backup SQL Data

Create a backup copy of a table called Customers into a table called Customers2 on a running database called Backup:

SELECT *
INTO Customers2 IN 'Backup.mdb'
FROM Customers;

You can also specify multiple tables to pull data from when bringing that data into a new table, effectively merging data into a backup database:

SELECT Customers.Site, IPs.IP
INTO CustomerIPsbackup
FROM Customers
LEFT JOIN IPs
ON Customers.Site=IPs.IP;

Since this is more like replication than backup, MySQL also has a mysqldump command, used to dump a sql database to a file or screen, or whatever. Here, we’ll export all of our databases in a running MySQL instance into a file called dumpfile.sql:

mysqldump --all-databases > dumpfile.sql
