Usage: [xtrabackup [--defaults-file=#] --backup | xtrabackup [--defaults-file=#] --prepare] [OPTIONS]

Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf ~/.my.cnf
The following groups are read: xtrabackup mysqld
The following options may be given as the first argument:
--print-defaults        Print the program argument list and exit.
--no-defaults           Don't read default options from any option file,
                        except for login file.
--defaults-file=#       Only read default options from the given file #.
--defaults-extra-file=# Read this file after the global files are read.
--defaults-group-suffix=#
                        Also read groups with concat(group, suffix)
--login-path=#          Read this path from the login file.
  -v, --version       print xtrabackup version information
  --target-dir=name   destination directory
  --backup            take backup to target-dir
  --stats             calc statistic of datadir (offline mysqld is recommended)
  --prepare           prepare a backup for starting mysql server on the backup.
  --export            create files to import to another database when prepare.
  --apply-log-only    stop recovery process not to progress LSN after applying
                      log when prepare.
  --print-param       print parameter of mysqld needed for copyback.
  --use-memory=#      The value is used instead of buffer_pool_size
  --use-free-memory-pct=#
                      This option specifies the percentage of free memory to be
                      used by buffer pool at --prepare stage (default is 0% -
                      disabled).
  --estimate-memory   This option enable/disable the estimation of memory
                      required to prepare the backup. The estimation happens
                      during backup. (Default OFF)
  --throttle=#        limit count of IO operations (pairs of read&write) per
                      second to IOS values (for '--backup')
  --log[=name]        Ignored option for MySQL option compatibility
  --log-copy-interval=#
                      time interval between checks done by log copying thread
                      in milliseconds (default is 1 second).
  --extra-lsndir=name (for --backup): save an extra copy of the
                      xtrabackup_checkpoints file in this directory.
  --incremental-lsn=name
                      (for --backup): copy only .ibd pages newer than specified
                      LSN 'high:low'. ##ATTENTION##: If a wrong LSN value is
                      specified, it is impossible to diagnose this, causing the
                      backup to be unusable. Be careful!
  --incremental-basedir=name
                      (for --backup): copy only .ibd pages newer than backup at
                      specified directory.
  --redo-log-arch-dir=name
                      Set redo log archive destination directory if not already
                      set in the server
  --incremental-dir=name
                      (for --prepare): apply .delta files and logfile in the
                      specified directory.
  --to-archived-lsn=# Don't apply archived logs with bigger log sequence
                      number.
  --tables=name       filtering by regexp for table names.
  --tables-file=name  filtering by list of the exact database.table name in the
                      file.
  --databases=name    filtering by list of databases.
  --databases-file=name
                      filtering by list of databases in the file.
  --tables-exclude=name
                      filtering by regexp for table names. Operates the same
                      way as --tables, but matched names are excluded from
                      backup. Note that this option has a higher priority than
                      --tables.
  --databases-exclude=name
                      Excluding databases based on name, Operates the same way
                      as --databases, but matched names are excluded from
                      backup. Note that this option has a higher priority than
                      --databases.
  --create-ib-logfile ** not work for now** creates ib_logfile* also after
                      '--prepare'. ### If you want create ib_logfile*, only
                      re-execute this command in same options. ###
  --stream[=name]     Stream all backup files using xbstream format. Files are
                      streamed to STDOUT or FIFO files depending on
                      --fifo-streams option. The only supported stream format
                      is 'xbstream'.
  --compress[=name]   Compress individual backup files using the specified
                      compression algorithm. Supported algorithms are 'lz4' and
                      'zstd'. The default algorithm is 'zstd'.
  --compress-threads=#
                      Number of threads for parallel data compression. The
                      default value is 1.
  --compress-chunk-size=#
                      Size of working buffer(s) for compression threads in
                      bytes. The default value is 64K.
  --compress-zstd-level=#
                      Zstandard compression level. from 1 - 19. The default
                      value is 1.
  --encrypt=name      Encrypt individual backup files using the specified
                      encryption algorithm.
  --encrypt-key=name  Encryption key to use.
  --encrypt-key-file=name
                      File which contains encryption key to use.
  --encrypt-threads=# Number of threads for parallel data encryption. The
                      default value is 1.
  --encrypt-chunk-size=#
                      Size of working buffer(S) for encryption threads in
                      bytes. The default value is 64K.
  --rebuild-threads=# Use this number of threads to rebuild indexes in a
                      compact backup. Only has effect with --prepare and
                      --rebuild-indexes.
  --incremental-force-scan
                      Perform a full-scan incremental backup even if page
                      tracking is enabled on server
  --close-files       do not keep files opened. Use at your own risk.
  --core-file         Write core on fatal signals
  --copy-back         Copy all the files in a previously made backup from the
                      backup directory to their original locations.
  --move-back         Move all the files in a previously made backup from the
                      backup directory to the actual datadir location. Use with
                      caution, as it removes backup files.
  --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. Has no effect when backup
                      locks are used to create the backup.
  --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 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 "xtrabackup_slave_info" file.
  --page-tracking     use the page-tracking server feature for incremental
                      backup instead of the full scan of data files. With
                      --page-tracking, xtrabackup will start page tracking on
                      the server during backup by invoking mysqlbackup
                      component service API. When --page-tracking is used
                      during subsequent incremental backup, it will use the
                      page-tracking file generated by the server to copy delta
                      pages modified since the last backup.
  --no-lock           Use this option to disable lock-ddl and 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
                      the system MyISAM tables in the mysql database),
                      otherwise it could lead to an inconsistent backup. If you
                      are considering to use --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 --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 this option.
  --lock-ddl          Issue LOCK TABLES/LOCK INSTANCE FOR BACKUP if it is
                      supported by server at the beginning of the backup to
                      block all DDL operations.
                      (Defaults to on; use --skip-lock-ddl to disable.)
  --lock-ddl-timeout=#
                      If LOCK TABLES FOR BACKUP does not return within given
                      timeout, abort the backup.
  --lock-ddl-per-table
                      Lock DDL for each table before xtrabackup starts the copy
                      phase and until the backup is completed.
  --backup-lock-timeout=#
                      Timeout in seconds for attempts to acquire metadata
                      locks.
  --backup-lock-retry-count=#
                      Number of attempts to acquire metadata locks.
  --dump-innodb-buffer-pool
                      Instruct MySQL server to dump innodb buffer pool by
                      issuing a SET GLOBAL innodb_buffer_pool_dump_now=ON
  --dump-innodb-buffer-pool-timeout=#
                      This option specifies the number of seconds xtrabackup
                      waits for innodb buffer pool dump to complete
  --dump-innodb-buffer-pool-pct=#
                      This option specifies the percentage of buffer pool to be
                      dumped
  --safe-slave-backup This option stops slave SQL thread at the start of the
                      backup if lock-ddl=ON or before copying non-InnoDB tables
                      if lock-ddl=OFF and waits 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.
  --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.
  --force-non-empty-directories
                      This option, when specified, makes --copy-back or
                      --move-back transfer files to non-empty directories. Note
                      that no existing files will be overwritten. If
                      --copy-back or --nove-back has to copy a file from the
                      backup directory which already exists in the destination
                      directory, it will still fail with an error.
  --no-server-version-check
                      This option allows backup to proceed when the server
                      version is greater (newer) than the PXB supported
                      version. (This option is deprecated).
  --no-version-check  This option disables the version check which is enabled
                      by the --version-check option.
  --tables-compatibility-check
                      This option enables engine compatibility warning.
                      (Defaults to on; use --skip-tables-compatibility-check to disable.)
  --no-backup-locks   This option controls if backup locks should be used
                      instead of FLUSH TABLES WITH READ LOCK on the backup
                      stage. It will disable lock-ddl. The option has no effect
                      when backup locks are not supported by the server. This
                      option is disabled by default, disable with
                      --no-backup-locks.
  --rollback-prepared-trx
                      Force rollback prepared InnoDB transactions.
  --decompress        Decompresses all the compressed files made with the
                      --compress option.
  -u, --user=name     This option specifies the MySQL username used when
                      connecting to the server, if that's not the current user.
                      The option accepts a string argument. See mysql --help
                      for details.
  -H, --host=name     This option specifies the host to use when connecting to
                      the database server with TCP/IP.  The option accepts a
                      string argument. See mysql --help for details.
  -P, --port=#        This option specifies the port to use when connecting to
                      the database server with TCP/IP.  The option accepts a
                      string argument. See mysql --help for details.
  -p, --password[=name]
                      This option specifies the password to use when connecting
                      to the database. It accepts a string argument.  See mysql
                      --help for details.
  -S, --socket=name   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. See mysql --help
                      for details.
  --incremental-history-name=name
                      This option specifies the name of the backup series
                      stored in the PERCONA_SCHEMA.xtrabackup_history history
                      record to base an incremental backup on. Xtrabackup will
                      search the history table looking for the most recent
                      (highest innodb_to_lsn), successful backup in the series
                      and take the to_lsn value to use as the starting lsn for
                      the incremental backup. This will be mutually exclusive
                      with --incremental-history-uuid, --incremental-basedir
                      and --incremental-lsn. If no valid lsn can be found (no
                      series by that name, no successful backups by that name)
                      xtrabackup will return with an error. It is used with the
                      --incremental option.
  --incremental-history-uuid=name
                      This option specifies the UUID of the specific history
                      record stored in the PERCONA_SCHEMA.xtrabackup_history to
                      base an incremental backup on.
                      --incremental-history-name, --incremental-basedir and
                      --incremental-lsn. If no valid lsn can be found (no
                      success record with that uuid) xtrabackup will return
                      with an error. It is used with the --incremental option.
  --decrypt=name      Decrypts all files with the .xbcrypt extension in a
                      backup previously made with --encrypt option.
  --remove-original   Remove .qp, .zst, .lz4 and .xbcrypt files after
                      decryption and decompression.
  --ftwrl-wait-query-type=name
                      This option specifies which types of queries are allowed
                      to complete before innobackupex will issue the global
                      lock. Default is all.
  --kill-long-query-type=name
                      This option specifies which types of queries should be
                      killed to unblock the global lock. Default is "SELECT".
  --history[=name]    This option enables the tracking of backup history in the
                      PERCONA_SCHEMA.xtrabackup_history table. An optional
                      history series name may be specified that will be placed
                      with the history record for the current backup being
                      taken.
  --kill-long-queries-timeout=#
                      This option specifies the number of seconds innobackupex
                      waits between starting FLUSH TABLES WITH READ LOCK and
                      killing those queries that block it. Default is 0
                      seconds, which means innobackupex will not attempt to
                      kill any queries.
  --ftwrl-wait-timeout=#
                      This option specifies time in seconds that innobackupex
                      should wait for queries that would block FTWRL before
                      running it. If there are still such queries when the
                      timeout expires, innobackupex terminates with an error.
                      Default is 0, in which case innobackupex does not wait
                      for queries to complete and starts FTWRL immediately.

                      not started until such long-running queries exist. This
                      option has no effect if --ftwrl-wait-timeout is 0.
