The command will create a backup of the sakila database and record it in the sakila.sql file.
CHANGE MYSQL BINLOG FORMAT TABLEPLUS FULL
To make a FULL database backup, run the following command: mysqldump -u user -p -flush-log -master-info=1 sakila > c:\backups\sakila.sql However, the first backup in the chain must be a FULL backup. Look up mysql56 (or something similar) in the list of servicesĪfter configuring MySQL Server, you can start creating incremental backups.Add the following text to the end of it.Make a backup copy of my.ini, just in case.If they are not enabled, you need to enable them. Preparing the Database for Incremental Backupsĭata will be recorded to binary logs if the ‘log_bin’ flag is on: show variables like 'log_bin' It is through them that data is synchronized. īinary logs are not only used for backups. Then, these SQL commands can be used to restore the data. The data in the binary log is recorded in binary format, but this data can be converted into SQL commands with the mysqlbinlogutility. You can also force the creation of a new file by executing the flush log sql command. When it reaches a certain size or after a specified time, a new binary log file is created, and transactions are recorded to it. Transactions are recorded only to the last file. The variable log_bin_basename stores a prefix for binary log files. The numeric index of the file is appended to the value of the log_bin_basename variable. To find out where the binary logs are stored, run the following: show variables like 'log_bin_basename' It will be discussed in detail below.Īny transaction that inserts, deletes, or updates data in MySQL also records that transaction in special files called binary logs.

Two Basic Ways to Make an Incremental Backup of MySQL on Windowsġ. Preparing the database for incremental backups Ways to make an incremental MySQL backupģ. Incremental backups are smaller, faster, and have almost no load on the database.ġ. In this case, to restore the data, you will need the entire chain of backups. Incremental backups do not contain all database data but only the data that changed since the previous backup. Therefore, instead of FULL database backups, you can do incremental database backups. This is not acceptable for a large production database. However, such backups are a heavy load on the database because they require a lot of space and take a long time to create. Making a full database backup is very easy with mysqldump.
