对于5.1和更高版本中创建的数据库,指定LSN作为一个单一的64位整数。

--kill-long-queries-timeout=SECONDS
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.

这个选项指定innobackupex 等待的秒数,在启动FLUSH TABLES WITH READ LOCK和杀死阻碍它的那些查询之间。
默认值是0秒,这意味着innobackupex将不会试图杀死任何查询。

This option specifies which types of queries should be killed to
unblock the global lock. Default is "all".
这个选项指定哪些类型的查询应该被杀死,来解锁全局锁。默认值是“all”。

--lock-wait-timeout=SECONDS
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.
这个选项指定innobackupex等待查询完成的时间,以秒为单位,在FTWRL运行之前阻止其运行。
如果还有这样的过期查询(超过了 timeout的时间),innobackupex终止并显示错误。
默认为0,在这种情况下innobackupex不等待查询完成,并立即开始FTWRL。

--lock-wait-threshold=SECONDS
This option specifies the query run time threshold which is used by
innobackupex to detect long-running queries with a non-zero value of --lock-wait-timeout.
FTWRL is not started until such long-running queries exist.
This option has no effect if --lock-wait-timeout is 0.
Default value is 60 seconds.
这个选项指定查询运行时间的阀值,
用于被innobackupex 检测到的"long-running queries" 是一个"--lock-wait-timeout"范围内的非零值。
FTWRL 不会启动,直到这个 "long-running queries "退出。
如果 --lock-wait-timeout 设置为 0,这个选项将没有效果。
默认值是60秒。
注: 指定查询时间的阀值,innobackupex检测长查询的值,如果该值小于--lock-wait-timeout定义的值,则执行 FTWRL前,等待长查询结束。
如果大于该值,则--lock-wait-timeout自动会对该查询采取动作。
如果 --lock-wait-timeout 设置为 0,这个选项将没有效果。

--lock-wait-query-type=all|update
This option specifies which types of queries are allowed to complete
before innobackupex will issue the global lock. Default is all.

--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.
移动之前备份的所有文件,从备份目录到实际datadir位置。
请谨慎使用,因为它消除了备份文件。

--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 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.
使用这个选项禁用表锁"FLUSH TABLES WITH READ LOCK"。
使用它,仅在所有的表是InnoDB表和不需要关注备份的二进制日志的位置信息。
这个选项不应该使用,如果任何DDL语句正在执行或者任何更新发生在非InnoDB表上(这包括MySQL数据库上的系统MyISAM表)
否则,可能导致不一致的备份。
如果你正在考虑使用 --no-lock,由于您的备份不能获得锁,这可能是由于传入复制事件防止获得锁。
请尝试使用 --safe-slave-backup 来暂时停止replication slave 线程,这可以帮助备份成功,并且你不必再使用此项。

--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.
给出这个命令行,这个选项可以防止在BACKUP-ROOT-DIR目录创建一个时间标记的子目录。
当它被定义,在BACKUP-ROOT-DIR目录完成备份。

--parallel=NUMBER-OF-THREADS

使用时,重建索引的时候,定义xtrabackup并行处理表空间的线程数量。

--redo-only
This option should be used when preparing the base full backup and when merging all incrementals except 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 to it later.
See the xtrabackup documentation for details.
这个选项应该被使用,在准备基础完整备份, 合并所有增量备份,除了最后一个.
这个选项直接传递给 xtrabackup的 --apply-log-only选项.
它强制xtrabackup跳过"rollback"(回滚)阶段,并只做"redo"(重做).
这是必要的,如果以后备份的增量变化将应用到它.

--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.

当指定此选项时,innobackupex使用rsync来复制所有的非InnoDB文件,而不是为每个文件生成一个单独的拷贝,
这非常快,对于具有大量的数据库或表的服务器。
这个选项不能与 --stream 一起使用。

--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.
停止 slave SQL_thread线程并且等待备份开始,直到Slave_open_temp_tables变量 在 "SHOW STATUS" 命令中显示的值是零。
如果没有打开的临时表,则备份会发生,否则SQL线程将被启动和停止,直到没有打开的临时表。
如果 Slave_open_temp_tables 的值在 --safe-slave-backup-timeout 定义的秒数之后还不是零,备份将失败。
备份完成后slave SQL_thread线程将会重新启动。

--safe-slave-backup-timeout
How many seconds --safe-slave-backup should wait for
Slave_open_temp_tables to become zero. (default 300)
在Slave_open_temp_tables 变成零之前,--safe-slave-backup 必须等待多少秒 。(默认是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 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.
备份复制slave服务器时,该选项很有用。
它打印master服务器上的二进制日志的名字和位置。
它也将这些信息写入到"xtrabackup_slave_info"文件,作为"CHANGE MASTER"命令的输入。
