Percona XtraBackup is an open source tool for performing hot backups of MariaDB, MySQL and Percona Server databases.
It can perform compressed, incremental and streaming backups. It was designed to back up XtraDB/InnoDB tables but can also back up other storage engines.
Note that XtraBackup (at least as of 2.4.4) will not work with MariaDB 10.1 encryption or compression, or when innodb_page_size is set to some value other than 16K.
If you want to use XtraBackup with uncompressed and unencrypted MariaDB data, use Percona XtraBackup 2.3 for MariaDB Server versions through 10.1 and use XtraBackup 2.4 for MariaDB Server versions beginning with 10.2.
XtraBackup 2.3 and 2.4 are both available from the MariaDB Package Repository. Note that XtraBackup 2.3 packages are called
percona-xtrabackup while XtraBackup 2.4 packages are called
MariaDB Backup is a fork of Percona XtraBackup designed to work with encrypted and compressed tables.
