Description: Xtrabackup has two main tools: Xtrabackup, Innobackupex
A, xtrabackup can only back up InnoDB and xtradb two kinds of data tables, but not the MyISAM data table
B, Innobackupex is a Perl script that encapsulates the xtrabackup. Supports the simultaneous backup of InnoDB and MyISAM engine tables.
