Backup Operations

This is the syntax to use when performing a backup, the most frequent kind of operation, and the most flexible with various options such as --compress and --incremental. For usage information and examples, see Section 3.3, “Backup Scenarios and Examples”.

mysqlbackup [STD-OPTIONS]
            [--exec-when-locked="utility arg1 arg2 ..."]
            [ { --incremental | --incremental-with-redo-log-only }
              { --incremental-base=dir:directory_path | 
                --incremental-base=history:last_backup |
                --start-lsn=LSN }
            [--only-innodb | --only-innodb-with-frm]
            backup | backup-and-apply-log | backup-to-image

Example 4.1 Simple Backup with Connection Parameters from Default Configuration File

The following example shows a minimal backup with the mysqlbackup command, with any necessary connection parameters for the database in the [mysqlbackup section of the default MySQL configuration file:

mysqlbackup --backup-dir=/export/backups/latest backup

Example 4.2 Basic Incremental Backup

mysqlbackup --incremental --start-lsn=12345 --incremental-backup-dir=/path/to/incbackup backup

There is a separate directory dedicated to incremental backup. Both this directory and the one for full backups can be specified in the my.cnf file, and the appropriate directory is used depending on the type of backup. Both the incremental backup data and an earlier full backup are needed to do a successful restore operation.
