 Options
 =======
 
-.. option:: --help
-
-   This option displays a help screen and exits.
-
-.. option:: --version
-
-   This option displays the |innobackupex| version and copyright notice and then exits.
-
 .. option:: --apply-log
 
    Prepare a backup in ``BACKUP-DIR`` by applying the transaction log file named :file:`xtrabackup_logfile` located in the same directory. Also, create new transaction logs. The InnoDB configuration is read from the file :file:`backup-my.cnf` created by |innobackupex| when the backup was made.
 
-.. option:: --redo-only
-
-   This option is passed directly to xtrabackup's :option:`xtrabackup --apply-log-only` option. This forces :program:`xtrabackup` to skip the "rollback" phase and do a "redo" only. This is necessary if the backup will have incremental changes applied to it later. See the |xtrabackup| :doc:`documentation <../xtrabackup_bin/incremental_backups>` for details.
+.. option:: --compress
+
+   This option instructs xtrabackup to compress backup copies of InnoDB data files. It is passed directly to the xtrabackup child process. See the :program:`xtrabackup` :doc:`documentation <../xtrabackup_bin/xtrabackup_binary>` for details.
+
+.. option::  --compress-threads
+
+   This option specifies the number of worker threads that will be used for parallel compression. It is passed directly to the xtrabackup child process. See the :program:`xtrabackup` :doc:`documentation <../xtrabackup_bin/xtrabackup_binary>` for details.
 
 .. option:: --copy-back
 
     Copy all the files in a previously made backup from the backup directory to their original locations.
 
-.. option:: --move-back
-
-    Move all the files in a previously made backup from the backup directory to their original locations. As this option removes backup files, it must be used with caution.
-
-.. option:: --include=REGEXP
-
-   This option is a regular expression to be matched against table names in ``databasename.tablename`` format. It is passed directly to :program:`xtrabackup` 's :option:`xtrabackup --tables` option. See the :program:`xtrabackup` documentation for details.
+.. option:: --databases=LIST
+
+   This option specifies the list of databases that |innobackupex| should back up. The option accepts a string argument or path to file that contains the list of databases to back up. The list is of the form "databasename1[.table_name1] databasename2[.table_name2] . . .". If this option is not specified, all databases containing |MyISAM| and |InnoDB| tables will be backed up. Please make sure that --databases contains all of the |InnoDB| databases and tables, so that all of the innodb.frm files are also backed up. In case the list is very long, this can be specified in a file, and the full path of the file can be specified instead of the list. (See option --tables-file.)
 
 .. option:: --defaults-file=[MY.CNF]
 
    This option accepts a string argument that specifies what file to read the default MySQL options from. It is also passed directly to :program:`xtrabackup` 's defaults-file option. See the :program:`xtrabackup` :doc:`documentation <../xtrabackup_bin/xtrabackup_binary>` for details.

-
-.. option:: --throttle
-
-   This option accepts an integer argument that specifies the number of I/O operations (i.e., pairs of read+write) per second. It is passed directly to xtrabackup's :option:`xtrabackup --throttle` option.
+.. option:: --defaults-group=GROUP-NAME
+
+   This option accepts a string argument that specifies the group which should be read from the configuration file. This is needed if you use mysqld_multi.
 
 .. option:: --export
 
    This option is passed directly to :option:`xtrabackup --export` option. It enables exporting individual tables for import into another server. See the |xtrabackup| documentation for details.
 
-.. option:: --use-memory
-
-   This option accepts a string argument that specifies the amount of memory in bytes for :program:`xtrabackup` to use for crash recovery while preparing a backup. Multiples are supported providing the unit (e.g. 1MB, 1GB). It is used only with the option :option:`--apply-log`. It is passed directly to |xtrabackup| 's :option:`xtrabackup --use-memory` option. See the |xtrabackup| documentation for details.
-
-.. option:: --password=PASSWORD
-
-   This option accepts a string argument specifying the password to use when connecting to the database. It is passed to the :command:`mysql` child process without alteration. See :command:`mysql --help` for details.
-
-.. option:: --user=USER
-
-   This option accepts a string argument that specifies the user (i.e., the *MySQL* username used when connecting to the server) to login as, if that's not the current user. It is passed to the mysql child process without alteration. See :command:`mysql --help` for details.
-
-.. option:: --port=PORT
-
-   This option accepts a string argument that specifies the port to use when connecting to the database server with TCP/IP. It is passed to the :command:`mysql` child process. It is passed to the :command:`mysql` child process without alteration. See :command:`mysql --help` for details.

+
+   This option accepts a string argument that specifies the directory in which to save an extra copy of the :file:`xtrabackup_checkpoints` file. It is passed directly to |xtrabackup|'s :option:`--extra-lsndir` option. See the :program:`xtrabackup` documentation for details.
+
+.. option:: --galera-info
+
+   This options creates the ``xtrabackup_galera_info`` file which contains the local node state at the time of the backup. Option should be used when performing the backup of Percona-XtraDB-Cluster.
+
+.. option:: --help
+
+   This option displays a help screen and exits.
 
 .. option:: --host=HOST
 
    This option accepts a string argument that specifies the host to use when connecting to the database server with TCP/IP. It is passed to the mysql child process without alteration. See :command:`mysql --help` for details.
 
-.. option:: --no-timestamp
-
-   This option prevents creation of a time-stamped subdirectory of the ``BACKUP-ROOT-DIR`` given on the command line. When it is specified, the backup is done in ``BACKUP-ROOT-DIR`` instead.

-
-   This options creates the ``xtrabackup_galera_info`` file which contains the local node state at the time of the backup. Option should be used when performing the backup of Percona-XtraDB-Cluster.
-
-.. option:: --slave-info
-
-   This option is useful when backing up a replication slave server. It prints the binary log position and name of the master server. It also writes this information to the :file:`xtrabackup_slave_info` file as a ``CHANGE MASTER`` command. A new slave for this master can be set up by starting a slave server on this backup and issuing a ``CHANGE MASTER`` command with the binary log position saved in the :file:`xtrabackup_slave_info` file.
-
-.. option:: --no-lock
-
-   Use this option to disable table lock with ``FLUSH TABLES WITH READ LOCK``. Use it only if ALL your tables are InnoDB and you **DO NOT CARE** about the binary log position of the backup.
-   If you are considering to use :option:`--no-lock` because your backups are failing to acquire the lock, this could be because of incoming replication events preventing the lock from succeeding. Please try using :option:`--safe-slave-backup` to momentarily stop the replication slave thread, this may help the backup to succeed and you then don't need to resort to using :option:`--no-lock`.
-
-.. option:: --ibbackup = 'autodetect'
-
-   This option accepts a string argument that specifies which xtrabackup binary should be used. The string should be the command used to run *XtraBackup*. The option can be useful if the :program:`xtrabackup` binary is not in your search path or working directory and the database server is not accessible at the moment. If this option is not specified, :program:`innobackupex` attempts to determine the binary to use automatically. By default, :program:`xtrabackup` is the command used. When option :option:`--apply-log` is specified, the binary is used whose name is in the file :file:`xtrabackup_binary` in the backup directory, if that file exists, or will attempt to autodetect it. However, if :option:`--copy-back` or :option:`--move-back` is used, :program:`xtrabackup` is used unless other is specified.

 .. option:: --incremental
 
-   This option tells :program:`xtrabackup` to create an incremental backup, rather than a full one. It is passed to the :program:`xtrabackup` child process. When this option is specified, either :option:`--incremental-lsn` or :option:`--incremental-basedir` can also be given. If neither option is given, option :option:`--incremental-basedir` is passed to :program:`xtrabackup` by default, set to the first timestamped backup directory in the backup base directory.

Normally, the only thing you might find convenient to place in the ``[xtrabackup]`` section of your :file:`my.cnf` file is the ``target_dir`` option to default the directory in which the backups will be placed, for example,

 This option is DEPRECATED and will be removed in Percona XtraBackup 2.1. In Percona XtraBackup 2.0 and later, you should use streaming backups instead. This option specifies the remote host on which the backup files will be created, by using an ssh connection.  The option accepts a string argument.

+Uses the rsync utility to optimize local file transfers. When this option is specified, innobackupex uses rsync to copy all non-InnoDB files instead of spawning a separate cp for each file, which can be much faster for servers with a large number of databases or tables.  This option cannot be used together with --remote-host or --stream.

 =item --safe-slave-backup
 
 Stop slave SQL thread and wait to start backup until Slave_open_temp_tables in "SHOW STATUS" is zero. If there are no open temporary tables, the backup will take place, otherwise the SQL thread will be started and stopped until there are no open temporary tables. The backup will fail if Slave_open_temp_tables does not become zero after --safe-slave-backup-timeout seconds. The slave SQL thread will be restarted when the backup finishes.

 This option specifies the socket to use when connecting to the local database server with a UNIX domain socket.  The option accepts a string argument. It is passed to the mysql child process without alteration. See mysql --help for details.

 This option specifies the format in which to do the streamed backup.  The option accepts a string argument. The backup will be done to STDOUT in the specified format. Currently, the only supported formats are tar and xbstream. This option is passed directly to xtrabackup's --stream option.
