Common backup methods of MySQL Database

MySQL database can be backed up in many ways, such as direct packaging of database files (physical cold backup), dedicated backup tool (mysqldump), binary log incremental backup, third-party tool backup and so on.

1. Physical cold backup

Physical cold backup needs to be in a closed state of the database, which can better ensure the integrity of the database. Physical cold backup is generally used for non-core business, which generally allows interruption. Physical cold backup is characterized by fast speed and the simplest recovery.

2. Dedicated backup tool mysqldump or mysqlhotcopy

Both the mysqldump program and mysqlhotcopy can be backed up. Mysqqldump is a common logical backup program on the client side, which can produce a set of SQL statements that are executed to reproduce the original database object definition and table data. It can dump one or more MySQL databases, back them up or transfer them to a remote SQL server. Mysqldump is more generic because it can back up various tables. Mysqlhotcopy is only available for some storage engines.

3. Incremental backup by enabling binary logs

MySQL supports incremental backups, and binary logging must be enabled for incremental backups. Binary log files provide users with replication and recovery of the information needed for database changes made after the backup point is executed. If you perform an incremental backup, which includes data modifications that have occurred since the last full backup or incremental backup, you need to refresh the binary log.
