----NOTE:
mysqlbackup: INFO: Could not find binlog index file. binlogs will not be copied for this backup.
Point-In-Time-Recovery will not be possible.
If this is online backup then server may not have started with --log-bin.
You may specify its location with --log-bin-index option.

/***************************參數
[backup_variables]
apply_log_done=1 # 是否釋放檢測ibbackup_logfile文件(0表示沒有,1表示已經釋放)
binlog_index=mysqldb01-bin.index #二進制日志索引文件
binlog_position=mysqldb01-bin.000011:338 #二進制日志文件大小
end_lsn=70249846 # 結束LSN點
has_external_plugins=0 #外部插件
is_compressed=0 #是否壓縮(0:否,1:是)
is_incremental=0 #是否是增量為增量備份文件(0:否,1:是)
is_incremental_with_redo_log_only=0 只配置重做日志,當輸入數據大小重做日志大小時,會有一場拋出
is_onlyinnodb=0 #是否只備份了innodb的表
is_partial=1 #是服務器備份還是部分備份（0表示全服務器備份,1表示部分備份）
is_skip_unused_pages=0
meb_version=3.12.0 #版本號
