千家信息网最后更新 2026年11月01日Percona XtraBackup 2.4 xtrabackup全量、增量备份恢复流程xtrabackup常用参数

--backup 创建备份并将备份存放到--target-dir目录

--defaults-file=[MY.CNF] 配置文件的路径

--target-dir=DIRECTORY 指定备份存放的路径。如果目录不存在，xtrabackup会创建相应的目录

--user 备份账户的用户名

--password 备份账户的密码

--datadir=DIRECTORY 数据目录的路径

--copy-back 将之前做的备份拷贝回他们的起始目录

--xtrabackup全量备份
