我可以在我的桌面上运行 Percona xtrabackup 吗？

  • 772

我已经在数据库服务器上成功运行 xtracbackup，但我真的想在另一台机器上运行备份（不是运行 MySQL 的机器）。
给定主机/端口选项，我尝试在桌面上运行 xtrabackup 工具，但出现以下错误：

我可以在另一台机器上运行备份吗？如果是，我还需要安装什么？谢谢！

    不，您不能在另一台机器上运行它，因为它直接读取数据文件，而不是通过 mysql 服务器进程。

    但是，您可以在数据库主机上挂载另一台机器的磁盘空间，并将该空间用作备份的目标目录。

  2. 如果您将另一台机器作为要备份的服务器的 mysql 从属服务器，则可以在该机器上使用 xtrabackup。
