The xtrabackup binary overview¶
The xtrabackup binary is a compiled C program that is linked with the InnoDB libraries and the standard MySQL client libraries.
xtrabackup enables point-in-time backups of InnoDB / XtraDB tables together with the schema definitions, MyISAM tables, and other portions of the server.
The InnoDB libraries provide the functionality to apply a log to data files. The MySQL client libraries are used to parse command-line options and configuration file.
The tool runs in either --backup or --prepare mode,
corresponding to the two main functions it performs. There are several
variations on these functions to accomplish different tasks, and there is one
less commonly used mode, --print-param.
