Xtrabackup is an open-source tool used to back up the InnoDB database of MySQL. It supports hot backup and Incremental backup with high performance.

The RedHat installation method is as follows:

1. Download RPM installation package (xtrabackup-1.4-74.rhel5.x86_64.rpm)
2. rpm-IVH xtrabackup-1.4-74.rhel5.x86_64.rpm

For how to install other systems (Windows, BSD, and UBUNTU), see here.

Backup:

1. Back up data to a directory:
Xtrabackup -- backup -- datadir =/var/lib/MySQL/-- target-Dir =/data/backups/MySQL/

For a detailed list of xtrabackup command parameters, see here.

You can directly add [xtrabackup] To My. CNF to specify the xtrabackup parameter, such as user and password, so that you do not need to enter the password during Backup.

2. Restore backup data

A. Stop MySQL service: $/etc/init. d/mysqld stop or service MySQL stop

B. modify my. CNF's datadir to the backup directory: datadir =/data/backups/MySQL/

C. Start the MySQL service: $/etc/init. d/mysqld start the latter Service MySQL start

It is quite simple. As for Incremental backup, you must specify the directory of the last backup during Backup.

Xtrabackup -- backup -- target-Dir =/data/backups/INC1 -- incremental-basedir =/data/backups/base -- datadir =/var/lib/MySQL/
