我可以在我的桌面上執行 Percona xtrabackup 嗎？

我已經在數據庫伺服器上成功執行 xtracbackup，但我真的想在另一台機器上執行備份（不是執行 MySQL 的機器）。

給定主機/埠選項，我嘗試在桌面上執行 xtrabackup 工具，但出現以下錯誤：

我可以在另一台機器上執行備份嗎？如果是，我還需要安裝什麼？謝謝！

不，您不能在另一台機器上執行它，因為它直接讀取數據文件，而不是通過 mysql 伺服器程序。

但是，您可以在數據庫主機上掛載另一台機器的磁碟空間，並將該空間用作備份的目標目錄。

如果您將另一台機器作為要備份的伺服器的 mysql 從屬伺服器，則可以在該機器上使用 xtrabackup。
