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

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 .)

-- Debug-sleep-before-unlock = SECONDS

This is a debug-only option used by the XtraBackup test suite.

-- Help

This option displays a help screen and exits.

-- Host = HOST

This option specifies the host to use when connecting to

Database server with TCP/IP. The option accepts a string argument.

It is passed to the mysql child process without alteration. See

Mysql -- help for details.

-- Ibbackup = IBBACKUP-BINARY

This option specifies which xtrabackup binary shocould be used.

Option accepts a string argument. IBBACKUP-BINARY shocould be

Command used to run XtraBackup. The option can be useful if

Xtrabackup binary is not in your search path or working directory.

If this option is not specified, innobackupex attempts to determine

The binary to use automatically. By default, "xtrabackup" is

Command used. However, when option -- copy-back is specified,

"Xtrabackup_51" is the command used. And when option -- apply-log is

Specified, the binary is used whose name is in the file

"Xtrabackup_binary" in the backup directory, if that file exists.

-- Include = REGEXP

This option is a regular expression to be matched against table

Names in databasename. tablename format. It is passed directly

Xtrabackup's -- tables option. See the xtrabackup documentation

Details.

-- Incremental

This option tells xtrabackup to create an incremental backup, rather

Than a full one. It is passed to the xtrabackup child process. When

This option is specified, either -- incremental-lsn or

-- Incremental-basedir can also be given. If neither option is given,

Option -- incremental-basedir is passed to xtrabackup by default, set

To the first timestamped backup directory in the backup base

Directory.

-- Incremental-basedir = DIRECTORY

This option specifies the directory containing the full backup that

Is the base dataset for the incremental backup. The option accepts

String argument. It is used with the -- incremental option.

-- Incremental-dir = DIRECTORY

This option specifies the directory where the incremental backup

Will be combined with the full backup to make a new full backup.

Option accepts a string argument. It is used with the -- incremental

Option.

-- Incremental-force-scan

This options tells xtrabackup to perform full scan of data files

Taking an incremental backup even if full changed page bitmap data

Is available to enable the backup without the full scan.

-- Log-copy-interval

This option specifies time interval between checks done by log

Copying thread in milliseconds.

-- Incremental-lsn

This option specifies the log sequence number (LSN) to use for

Incremental backup. The option accepts a string argument. It is used

With the -- incremental option. It is used instead of specifying

-- Incremental-basedir. For databases created by MySQL and Percona

Server 5.0-series versions, specify the LSN as two 32-bit integers

In high: low format. For databases created in 5.1 and later, specify

The LSN as a single 64-bit integer.

-- Move-back

Move all the files in a previusly made backup from the backup

Directory to the actual datadir location. Use with caution, as it

Removes backup files.

-- 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. This option shouldn't

Be used if there are any DDL statements being executed or if any

Updates are happening on non-InnoDB tables (this includes des the system

MyISAM tables in the mysql database), otherwise it cocould lead to

Inconsistent backup. If you are considering to use -- no-lock because

Your backups are failing to acquire the lock, this cocould be because

Of incoming replication events preventing the lock from succeeding.

Please try using -- safe-slave-backup to momentarily stop

Replication slave thread, this may help the backup to succeed and

You then don't need to resort to using this option.

-- No-timestamp

This option prevents creation of a time-stamped subdirectory of

BACKUP-ROOT-DIR given on the command line. When it is specified,

Backup is done in BACKUP-ROOT-DIR instead.

-- Parallel = NUMBER-OF-THREADS

This option specifies the number of threads the xtrabackup child

Process shocould use to back up files concurrently. The option accepts

An integer argument. It is passed directly to xtrabackup's

-- Parallel option. See the xtrabackup documentation for details.

-- Password = WORD

This option specifies the password to use when connecting to

Database. It accepts a string argument. It is passed to the mysql

Child process without alteration. See mysql -- help for details.

-- Port = PORT

This option specifies the port to use when connecting to

Database server with TCP/IP. The option accepts a string argument.

It is passed to the mysql child process. It is passed to the mysql

Child process without alteration. See mysql -- help for details.

-- Rebuild-indexes

This option only has effect when used together with the -- apply-log

Option and is passed directly to xtrabackup. When used, makes

Xtrabackup rebuild all secondary indexes after applying the log.

This option is normally used to prepare compact backups. See

XtraBackup manual for more information.

-- Rebuild-threads

This option only has effect when used together with the -- apply-log

And -- rebuild-indexes option and is passed directly to xtrabackup.

When used, xtrabackup processes tablespaces in parallel with

Specified number of threads when rebuilding indexes. See

XtraBackup manual for more information.

-- Redo-only

This option shoshould be used when preparing the base full backup and

When merging all incrementals failed t the last one. This option is

Passed directly to xtrabackup's -- apply-log-only option. This forces

Xtrabackup to skip the "rollback" phase and do a "redo" only. This

Is necessary if the backup will have incremental changes applied

It later. See the xtrabackup documentation for details.

-- Rsync

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 -- stream.

-- Safe-slave-backup

Stop slave SQL thread and wait to start backup

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.

-- Safe-slave-backup-timeout

How many seconds -- safe-slave-backup shocould wait

Slave_open_temp_tables to become zero. (default 300)

-- 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 "xtrabackup_slave_info" file

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

"Xtrabackup_slave_info" file.

-- Socket = SOCKET

This option specifies the socket to use when connecting to the local

Database server with a UNIX domain socket. The option accepts

String argument. It is passed to the mysql child process

Alteration. See mysql -- help for details.

-- Stream = STREAMNAME

This option specifies the format in which to do the streamed backup.

The option accepts a string argument. The backup will be done

STDOUT in the specified format. Currently, the only supported

Formats are tar and xbstream. This option is passed directly

Xtrabackup's -- stream option.

-- Tables-file = FILE

This option specifies the file in which there are a list of names

The form database. The option accepts a string argument. table, one

Per line. The option is passed directly to xtrabackup's

-- Tables-file option.

-- Throttle = IOS

This option specifies a number of I/O operations (pairs

Read + write) per second. It accepts an integer argument. It is passed

Directly to xtrabackup's -- throttle option.

-- Tmpdir = DIRECTORY

This option specifies the location where a temporary file will be

Stored. The option accepts a string argument. It shocould be used when

-- Stream is specified. For these options, the transaction log will

First be stored to a temporary file, before streaming. This option

Specifies the location where that temporary file will be stored. If

The option is not specified, the default is to use the value

Tmpdir read from the server configuration.

-- Use-memory = B

This option accepts a string argument that specifies the amount

Memory in bytes for xtrabackup to use for crash recovery while

Preparing a backup. Multiples are supported providing the unit (e.g.

1 MB, 1 GB). It is used only with the option -- apply-log. It is passed

Directly to xtrabackup's -- use-memory option. See the xtrabackup

Documentation for details.

-- User = NAME

This option specifies the MySQL username used when connecting to

Server, if that's not the current user. The option accepts a string

Argument. It is passed to the mysql child process

Alteration. See mysql -- help for details.
