--slave-info

When backing up a replication slave server, this option captures information needed to set up an identical slave server. It creates a file meta/ibbackup_slave_info inside the backup directory, containing a CHANGE MASTER statement with the binary log position and name of the binary log file of the master server. This information is also printed in the mysqlbackup output. To set up a new slave for this master, restore the backup data on another server, start a slave server on the backup data, and issue a CHANGE MASTER command with the binary log position saved in the ibbackup_slave_info file. See Section 5.4, “Setting Up a New Replication Slave” for instructions.

--suspend-at-end

This option pauses the mysqlbackup command when the backup procedure is close to ending. It creates a file called ibbackup_suspended in the backup log group home directory and waits until you delete that file before proceeding. This option is useful to customize locking behavior and backup of non-InnoDB files through custom scripting.

All tables are locked before suspending, putting the database into a read-only state, unless you turn off locking with the --no-locking or --no-connection option. The --only-innodb and --only-innodb-with-frm options also prevent the locking step. Because locking all tables could be problematic on a busy server, you might use a combination of --only-innodb or --only-innodb-with-frm and --suspend-at-end to back up only certain non-InnoDB tables.

--exec-when-locked="utility arg1 arg2 ..."

You can use this option to write a script that backs up any information that is not part of the usual backup, for example by using mysqldump to back up tables from the MEMORY storage engine that are not on disk.

Within your script, the BACKUP_DIR environment variable is set and points to the current backup directory. Use single quotes to prevent premature expansion of $BACKUP_DIR, as in the following examples.

On Unix or Linux systems:

mysqlbackup --exec-when-locked='mysqldump mydb t1 > $BACKUP_DIR/t1.sql' other_options

Or on Windows systems:

mysqlbackup --exec-when-locked="mysqldump mydb t1 > %BACKUP_DIR%/t1.sql" other_options

If the utility cannot be executed or returns a non-zero exit status, then the whole backup process is cancelled. If you also use the --suspend-at-end option, the utility specified by --exec-when-locked is executed after suspending.
