# *Percona XtraBackup* User Manual #

*Percona XtraBackup* is a set of following tools:

[innobackupex][]

a wrapper script that provides functionality to backup a whole  *MySQL* database instance with  [MyISAM][],  [InnoDB][], and  [XtraDB][] tables.

[xtrabackup][]

a compiled  *C* binary, which copies only  [InnoDB][] and  [XtraDB][] data

[xbcrypt][]

utility used for encrypting and decrypting backup files.

[xbstream][]

utility that allows streaming and extracting files to/from the  [xbstream][xbstream 1] format.

It is possible to use the **xtrabackup** binary alone, however, the recommend way is using it through the **innobackupex**wrapper script and let it execute **xtrabackup** for you. It might be helpful to first learn [how to use innobackupex][innobackupex], and then learn [how to use xtrabackup][xtrabackup] for having a better low-level understanding or control of the tool if needed.
