如何設置由Percona xtrabackup生成的備份目錄的名稱？

Question

我已經安裝了percona-xtrabackup-24.2.4.4來完成MySql數據庫的完整備份。我運行下面的命令取備份

innobackupex --user=user_name --password=pass dir_path 

它創建的目錄具有時間戳（例如2016-09-26_12-36）的MySQL DB成功，其含有完整的DB備份。

問題是，我想指定輸出目錄名稱，默認情況下這是使用時間戳創建的。

有什麼建議嗎？我已閱讀所有選項percona提到，但一無所獲。

Answer 1

如果我瞭解清楚，我建議你需要像水木清華

innobackupex --user=yourDBuser --password=MaGiCdB1 --no-timestamp /path/to/backupdir 

其中

--no時間戳鍵告訴不創建一個時間標記目錄來存儲備份

/path/to/backupdi r - 備份的路徑fi樂

您可以找到有關--no時間戳選擇這裏

Bilal，使用較新版本的Percona Xtrabackup，您不需要使用innobackupex腳本。 xtrabackup二進制文件可以爲您創建備份。使用以下表示法，您可以使用自定義輸出目錄創建備份;

[moore@randy backup]$ pwd 
/data/backup 

[moore@randy backup]$ sudo xtrabackup --user=root \ 
--password=*** \ 
--backup \
